  • Bowen Basin Coalfields of Central Queensland (Figure 1)
    The South African Institute of Mining and Metallurgy International Symposium on Stability of Rock Slopes in Open Pit Mining and Civil Engineering John V Simmons and Peter J Simpson COMPOSITE FAILURE MECHANISMS IN COAL MEASURES ROCK MASSES – MYTHS AND REALITY John V Simmons Sherwood Geotechnical and Research Services Peter J Simpson BMA Coal Pty Ltd Central Queensland Office 1. INTRODUCTION Excavated slopes in open pit coal mines are designed to be as steep as possible consistent with stability and safety requirements. Slope failures occur for many reasons, including oversteepening. This paper is concerned with slope design and excavation experience in the Bowen Basin coalfields of central Queensland (Figure 1), Bowen Basin Coalfields Figure 1 Location of Bowen Basin open pit coal mines in eastern Australia Page 31 The South African Institute of Mining and Metallurgy International Symposium on Stability of Rock Slopes in Open Pit Mining and Civil Engineering John V Simmons and Peter J Simpson but it deals with many issues that are common to open pit coal mining generally. After more than three decades of operational experience and technological advances in the Bowen Basin mines, sudden rock slope failures still occur in circumstances where personnel and equipment are at extreme risk. The circumstances of a selection of these sudden failures are reviewed in this paper, and some concerning trends emerge. Classical structurally-controlled slope failures occur quite rarely in the Bowen Basin, but rock mass structures appear to exert important controls on the sudden failures that are more widely experienced. The term "composite" is used in this paper to describe failures involving combinations of intact rock material fracture and shear movement on defects (Baczynski, 2000).

The profit for the year was slightly higher than the 2006 result of $68.7 million and continues a trend of New Hope increasing its profit for its Australian operations in each of the last five years. Higher coal sales tonnages and higher coal prices in US dollar terms, and the sale of some surplus land during the year, were offset by lower interest revenue and a lower contribution from our port operations during the year.

  • Evaluation of the Gas Drainage Efficiency at the Grasstree Mine
    THE UNIVERSITY OF QUEENSLAND Bachelor of Engineering Thesis Evaluation of the Gas Drainage Efficiency at the Grasstree Mine Student Name: Michael VAN DER MEER Course Code: MINE4123 Supervisor: Associate Professor Mehmet Kizil and Doctor Saiied Aminossadati Submission date: 6 November, 2017 A thesis submitted in partial fulfilment of the requirements of the Bachelor of Engineering (Hons) degree in Mining Engineering (Extended Major) UQ Engineering Faculty of Engineering, Architecture and Information Technology i ABSTRACT Inappropriate coal mine gas management has the potential to cause catastrophic disasters resulting in multiple fatalities. Gas is naturally released into the mining work environment during production and development; pre- and post-drainage form the basis of gas management. The Grasstree Mine site located in the Bowen Basin is an underground coal mine that utilises both pre- and post-drainage techniques. Unique to Grasstree is the high gas content of the mining and adjacent seams. This project studies the methane capture efficiency of the GC906 longwall panel against critical events that affect the gas management and ventilation of the mine. The aim is to identify the most effective gas management techniques for future longwall blocks with reduced ventilation at the Grasstree Mine. The data utilised in this project was post-drainage flows and concentrations provided from measurements and recordings taken for the full duration of GC906 mining. Methane capture efficiency was calculated for each hour for the duration of GC906 longwall mining; 18/11/2016-21/06/2017. The critical events analysed were: Initial longwall square-up period; Transitioning from two to three return gateroads; Full duration of a HGH well transitioning from long to short goaf gas drainage; The restriction of a return roadway to improve goaf dynamics; and Analysis of the effects of vertical post-drainage holes over the maingate side on the overall gas drainage.

An extensive geotechnical database across the mine site area must be considered for mine planning and design. Some geotechnical parameters can be defined through the analysis of an appropriate suite of geophysical logs, including the acoustic scanner and sonic velocity logs and by incorporating a strict hybrid logging classification system. The acoustic scanner tool is becoming part of the standard geophysical logging suite used today in all stages of exploration drilling.
