My heartiest congratulations and thanks to all the Chapters for celebrating Indian Mining Day on 1st November in a grand manner involving other professional organizations and institutions. Many Chapters conducted Essay Competition on the topic "Role of Management for Safety in Mines" given by the Head Quarters. Coverage in print media and electronic media was also excellent this year and helped generating awareness of benefits of mining to public at large. For the remaining period of FY 2017–18, all the Chapters’ Chairmen and Secretaries are requested to make a drive to enroll maximum new Life Members and Life Institutional Members. This will be one of the criteria for selection of Best Chapter in the Country and will be honored with a Certificate and Rs. 10000 as additional assistance to that Chapter. Two mega events are coming up in December - An International Conference & Expo on Mining Industry Vision 2030 & Beyond at Nagpur between 6th to 8th December, in association with Indian Bureau of Mines; and a National Seminar on New Paradigms in Exploration of Oil and Solid Fuels at Jaipur between15th to 17th December. Both the events aim to bring new dimensions in mining sector, especially when contribution to GDP and employment from mining sector needs a boost. We have also launched Members' Data Base Portal for our members on 1st of November and now it is functional on our web site www.meai.org and our members can start using it. All the members are requested to register their details on this portal at the earliest possible. All the members are again requested to register themselves with SME at the earliest. Otherwise, they will be deprived from SME membership advantage. MEJ is a nationally recognized publication of MEAI and to maintain its qualitative edge, good technical papers related to Mining are published in it. We encourage all the members to continue providing insightful articles and research papers to be published in it, and suggest their distinguished colleagues and acquaintances for providing articles and research papers that may help mining industry. Apart from nationwide circulation and recognition, there is also an annual MEAI Eco-friendly Mining Award for the best paper published in MEJ. By the time you receive this copy of December MEJ, the draft of National Mineral Policy, 2017 may be made available on the website of Ministry of Mines, GOI for inviting suggestions of public. Even though we had already given our suggestions during meetings for the making of this draft, we can give further representation within the time provided. Therefore, if any member has suggestions for inclusion in the Draft Policy, he can send them to Secretary General with a copy to me by mail for consideration. After successful first Council Meeting held in Hyderabad, second Council Meeting shall be held inJaipur on 15th December, 2017 along with Extra Ordinary General Meeting to ratify the important Constitutional amendments and also MEJ Editorial Board Meeting to consider the improvements in Quality of MEJ. All the members are requested to attend the meetings and give their valuable suggestions to give boost to activities of MEAI. In continuing our drive for achieving financial independence of MEAI, I am happy to inform that members have generously made their personal contributions in the last few months but this drive needs to gain more momentum to achieve the necessary goals. I again make a humble request to all the members to willingly contribute to your organization generously, keeping in mind that an early donation makes us stronger. Jai Hind.

Mining Engineers’ Journal, Vol. 19, No. 5 9 December 2017 APPLICATION OF SLOPE STABILITY RADAR IN AN OPENCAST MINE *Sandi Kumar Reddy1 James Paul2 and Paul Prsanna Kumar2 ABSTRACT The management of risks associated with slope instability is an essential process in the safe and economic operation of opencast mines. The ‘Slope Stability Radar’ (SSR) has been developed to better manage those risks. The SSR remotely scans rock slopes to continuously measure any surface movement and can be used to detect and alert users of wall movements with sub-milli meter precision. The high level of movement precision and broad area coverage of the rock face allows for a better understanding of the geo-mechanics of slope deformation, including magnitude of potential failures and additional warning time of impending instability. Additionally, radar waves adequately penetrate through rain, dust and smoke to give reliable measurements, 24 hours a day.

SSR systems have been deployed throughout the world in many mines and failures have been monitored, and on every occasion precursor ‘warning’ movements were recorded by the SSR. This technology enables a radical change in the management of risks in opencast mining. This paper presents details of SSR and its operation, and detection of dump failure in a coal mine.

Key Words: Slope stability Radar, Open pit mining, Slope movement monitoring

INTRODUCTION The management of risk to personnel, equipment and SSR is now being widely used in several countries to provide continued production associated with slope instability is real time monitoring and advance warning signals before any one of the key roles of geotechnical and mining engineers slope failure in opencast mines. The SSR system produces in opencast mines. The importance of slope angles, slope data for interpretation usually within minutes. The data from instability and striping ratios on the economics of open pit the slope stability radar is presented in two formats. Firstly, operations is well recognized, and a flatter slope always as a coloured “rainbow plot” of total movement which quickly means better stability, it also involves permanent locking enables the user to determine the extent of the failure and up of huge quantities of mineral reserves. On the contrary, where the greatest movements are occurring, which is useful steeper slope greatly increases the potential of failures. to characterize the type of failure. Secondly, any number of Therefore, a scientific balance must be constantly established time/displacement graphs can be created at any locations between the two situations catering to the expected life of within the scan area to evaluate displacement rates and aid the benches. in the creation of alarm triggers for action response plans.

The rock slope design role often incorporates some degree Harries et al., (2-3) describe the application of the SSR of risk management, either explicitly or implicitly in the technology at numerous open-pit mines where it has design of pit slopes. Nevertheless, unexpected failures have been successfully used to monitor and provide impending occurred in the past and continue to do so today. These slope warning of pit slope failures just tens of minutes to hours failures motivated the development of the Slope Stability before failure. The authors (4-6) provide well-documented Radar (SSR) (Harries et al., (2006)). The SSR system can examples of the benefits of this technology in managing detect and alert movements of a wall with sub-millimetre the risks due to slope stability at major open-pit mines.

MINE DUMP MONITORING BY SSR An opencast coal mine located in Southern India is operating with a production capacity of 1.4 million tonne per annum with mineable reserves of 9.75 million tonnes and having a coal seam thickness of about 14 m at a depth of approximately 120 m. In this mine, the coal seam is being extracted by deploying hydraulic excavators in combination Figure 5a. Before rock fall in the mine with dumpers, and overburden removal is done by both shovel-dumper combination as well as dragline. The dragline

Mining Engineers’ Journal, Vol. 19, No. 5 12 December 2017 In this study, the monitoring of dump slopes using SSR with integrated visual imaging system gave a real-time monitoring of displacements of dumps well in advance of any failure and providing mine management sufficient time to safely withdraw men and machinery from such areas. Such systems would not only increase safety but also the productivity and efficiency of opencast operations.

The SSR technology has enabled a radical change in the management of risks in open cut mining operations, which has resulted in a rapid take-up of the technology throughout Figure 6a.SSR pixilated image of dump failure in the mine the world to date. At a number of mines, the SSR is now an integral part of the mine providing major contributions to the mine’s future plans. It is also believed that the SSR will contribute significantly to safety and mine design by providing accurate, reliable deformation data that may be later reviewed to further develop our understanding and analysis of failure mechanisms in open pit mines; eventually leading to improved slope design.

The precision of measurements is usually an important task, as well as the expended amount of time and money is important. It is not necessary to reach sub-centimetre precision in case of the regular monitoring of shallow landslide due to the effort to the evaluation of the whole landslide body. Unmanned aerial vehicles provide the great improvement in the efficiency of the process, and they also broaden possibilities in the visualization while the accuracy is still preserved on the suitable level. The contribution aims to present the current observation of shallow landslide, which has been monitored for 6 years using geodetic measurements. Recently, the conventional surveying activities are complemented by the photogrammetric methods (Drone Pixy or Hexacopter), which allows not only the monitoring of selected measuring points but also the complex monitoring and precise evaluation of the general shape of the landslide body.

It is often the only solution conventional platforms (aircrafts and satellites) highlight for the survey and the early-warning of large landslides some drawbacks such as the high costs and the difficult that cannot be stabilized or that may accelerate suddenly repeatability in a short time.

Mining Engineers’ Journal, Vol. 19, No. 5 15 December 2017 hydrologic conditions are important elements for design of safe and efficient slope structures. Groundwater, surface water, and precipitation runoff can be controlled to abate their deleterious effects on stability. Benches and berms are normally used to stop rocks before to fall prior and pose a significant hazard. Mechanical rock fall catchment systems or secondary supports may also be used to stabilize slopes in particular locations. However, even a carefully designed and constructed slope may fail because of unidentified geological structures, unexpected weather conditions, or seismic activities. For these reasons, regular examination and systematic monitoring of slopes are important for early detection of failure and associated hazard.

Slope never fails spontaneously. Prior to failure, slope provides indication in the form of measurable movement Fig 1: Slope geometry overview and/or the development of tension cracks. In contrast to this, landslide is a result of long term movement of slopes be safe for hard formations by Directorate General of Mines creeping for hundreds of years resulting in accumulative Safety (DGMS). The curvature of the slope has profound movement of tens of meters. Such movement may be effect on the instability and therefore convex section slopes superimposed for a short period of more rapid movement should be avoided in the slope design. Steeper and higher resulting from major events like earthquakes. Under such the height of slope, less is the stability. conditions, monitoring of slope stability and landslides involve selection of certain parameters and observing their Slope failure mechanism: behaviour with respect to time.

Mining Engineers’ Journal, Vol. 19, No. 5 16 December 2017 Sub surface Monitoring methods: Sub-surface measurement is an useful component of a monitoring program to obtain a more complete picture of the slope behavior. The main purpose of these measurements is to locate the slide surface or sub surfaces, and monitor the rate of movement. In some cases, the holes are used for monitoring both movement and pore water pressures. There are various methods being used for slope minoring as enumerated below. 1. Borehole probes: One of the simplest sub-surface monitoring methods is the borehole probe comprising a length of reinforcing steel about 2m long that is lowered down the drill hole on a length of rope. If the hole intersects a moving slide plane, the hole will be displaced at this level and it will no longer be possible Figure 2: Analysis of slope monitoring results (a) Regressive movement, to pull the bar pass this point.

However, it is possible instruments used to measure horizontal displacements that mining can safely continue under these conditions along various points on a borehole. For this reason, with the implementation of a monitoring system. sometimes they are also called borehole inclinometers Eventually, an “operational slope failure” may develop or simply inclinometers.

Mining Engineers’ Journal, Vol. 19, No. 5 19 December 2017 Mining Engineers’ Journal, Vol. 19, No. 5 20 December 2017 Readers' Views Dr Rao, As always, I read the MEJ November issue with great interest. I have two comments: 1. I am writing to express my support to Mr Kothari’s request to all MEAI Chapters to strictly abide by the provisions of the Association’s Constitution. In my opinion, all the members acting as volunteers in various committees and chapters should take this seriously. 2. I see substantial improvements in MEJ: I know that any publication such as MEJ (monthly magazine of the MEAI) grows and improves when highly respected professionals lead the society and the magazine. I am aware that many readers returned to MEJ after you accepted the editorship of the MEJ and Mr Kothari expressed his willingness to revamp MEAI. I am also noticing that industry is supporting MEJ’s publication through advertisements. I congratulate both of you. There is still room for improvement. We may need to do something to improve the quality of technical articles through a peer review process. Regards, Abani R Samal

Dear Dr. Rao, The magazine is coming up very well. I am proud to say that it is in the right hands.

Now looking into our economy it is better to reduce the imports of coal and oil, which are costing thousands of crores monthly. It is necessary to invite papers in short from our intellectuals of our mining community to improve the production and quality of our coal and also to think and suggest of cheaper alternative energies to reduce the usage of oil and coal in our country.

A forum of judges can choose the best paper and honour the author and forward the paper to our leaders to implement. Yearly evaluation of such acts will help our country as a whole. Please look into this aspect. Regards V. Nagaraj, Bengaluru
