  • The Differences in Underground Mines Dewatering with The
    International Mine Water Association Symposium Zambia 1993 | © IMWA 2009 | www.IMWA.info THE DIFFERENCES IN UNDERGROUND MINES DEWATERING YVITH THE APPLICATION OF CAVING OR BACKFILLING MINING METHODS By Vladimir Straskraba(l) and John F. Abel, JrY) (1) President, Hydro-Geo Consultants, Inc. (2) Prof. Emeritus, Colorado School of Mines ABSTRACT Zambia Consolidated Copper Mines, Ltd. (ZCCM) is planning a substantial increase in ore production in several of their underground mines on the Zambian Copperbelt over the next 10 years. Tne future production stratcb'Y is based on development of productive and economic mining methods through the application of mechanization and backfilling. Mechanization is designed to provide the production capability and the back.iilling is designed to reduce water flow into the mines. A similar trend can be seen in world-wide changes in mining methods from open stoping and sub-level caving to cut-and-fill stoping. Backfill is being empluyed v,'orldwide, including in Australia, Canada, Sweden, Latin America, ambia, and the U.S.A Plans for backfill mining methods are underway for future operations in Chile, Canada, Zambia, and :'vfexico. The principal reasons for these changes in mining methods is twofold: • Increased ore recovery, and • Decreased environmentai impact. The main difference in [he environmental impacts between mining with sub-level caving or open stoping and mining with backfiJiing methods is the reduction in subsidence or the potential for subsidence. Backfilling reduces ground movements in the rock overlying and adjacent to mine openings as well as subsidence at the surface, Reduced ground movement decreases the number and size offracture-controlled hydraulic flow paths into a mine and, thereby, the impact of mining on surface and ground water resources.

  • Environmental Factors of Blasting Report for the Proposed Idaho-Maryland Gold Project Nevada County, CA
    September 27, 2019 Attention: Rise Grass Valley Inc. Subject: Environmental Factors of Blasting Report for the Proposed Idaho-Maryland Gold Project Nevada County, CA EXECUTIVE SUMMARY Precision Blasting Services (PBS) has been retained by Rise Grass Valley Inc. (Rise) to provide a description of the proposed blasting at the Idaho Maryland Mine (IMM) and potential environmental impacts from the blasting. This report includes an overview of vibration and blasting ground vibration, the effects of ground vibration on various structures, methodology for determining ground borne vibration levels, proposed IMM blasting activities, the total magnitude of ground vibration expected from IMM blasting at various depths and horizontal distances, and air overpressure. In addition, a monitoring program has been recommended to establish background levels, record ground vibration, and model the ground vibration. PBS has determined that potential impacts of drilling and blasting to the surrounding community will be negligible. The impact from exposure of persons to or generation of excessive ground vibration created by blasting will be less than significant. The U.S. Bureau of Mines (USBM) and Office of Surface Mining, Reclamation, and Enforcement (OSMRE) have both developed recommendations for ground vibration levels to prevent damage to residential structures. The estimated ground vibration from IMM blasting activities are typically less than 10% of these limits and present no risk of damage to any nearby receptors. The author recommends that blasting vibrations at the location of receptors on surface be kept below a threshold of 0.4 in/s to minimize annoyance and complaints. Maximum predicted blast vibrations at IMM will typically be less than 50% of this 0.4 in/s threshold level and should not cause concerns amongst the local community.

  • Intro to Mining
    Unit 16 Mine Development In this unit, you will learn how a Mine is developed for production, how a shaft is sunk, how lateral headings and raises are mined. After completing this unit, you should be able to: • Explain the methods of "opening a deposit" • Lists the steps of shaft sinking • Lists the type of shafts • Big Hole Drilling • Ground Freezing • Shaft Linings • Lateral Development & Ramps • Track versus Trackless • Design and function of Lateral Headings • Laser Control • Raises Mine Development When a promising mineral deposit has been found, production is the next thing to consider. All mines require considerable development before actual ore production can begin. The orebody is "opened up" by excavation. In opening a mine, a small mining company usually digs any ore that is showing. The revenue from the sale of the ore keeps the venture going and finances further development. After the ore body has been delineated and defined, a company may make several feasibility studies to determine the best way to mine the ore. Opening a deposit A) Open Pit Stripping the overburden is always a problem. The wider and richer the vein the deeper the pit. The availability and production capability of surface equipment makes open-pit mining a very attractive choice. B) Drift Mining If the ore vein is narrow and the terrain is favourable, a drift or adit on the vein is often used. The drift is mined into the vein at an almost flat elevation. C) Inclined Shaft In flat terrain, a shaft is almost always required in a narrow vein.

I (Mar. - Apr. 2016), PP 15-22 www.iosrjournals.org A Review of Geology and Coal Mining In South Eastern Nigeria: Implication for Sustainable National Development 1Abalaka, I. E. and 2 Aga, T. Department of Geology, University of Jos, Nigeria. Abstract: Coal is a combustible carbonaceous material which occurs within the Campanian – Maactrictian Mamu formation of the Anambra Basin, Nigeria. The estimated total reserve is about 2.7 billion tones with over 0.6 billion tones proven (Dixon and Leighton L. H. 1969) coal mining has been successfully carried out using conventional underground mining methods as well as long or all mining methods. Although, coal mining activity ceased in the Enugu for some times now,the current policy of the government to commercialize the coal mining industry is expected to bring a boom in the sector. This will no doubt increase Nigeria foreign direct investment (FDI). Apart from its industrial uses, coal is a good alternative to fuel wood as it can be processed into coal briquettes which can be adapted in the rural and urban areas for use in coking. This effort will not only diversify Nigerian monolithic economy but will lead to reduction in the unemployment rate and by implication reduction in youth restiveness. I. Introduction Coal is often described as a broad name given to stratified accumulations of carbonaceous material derived from vegetation (Dixon and Leighton1969). It is a brownish black complex combustible rock that has its origin from biochemical process and physio chemical alteration of vegetation.

  • Gold Formation, Extraction, and Refining in the Sierra Nevada Mountain Region Isabella Niloofar Cross-Najafi ABSTRACT Gold Forma
    Cross‐Najafi 1 Gold Formation, Extraction, and Refining in the Sierra Nevada Mountain Region Isabella Niloofar Cross-Najafi ABSTRACT Gold formation processes include hydrothermal processes in which water becomes heated underground when it is close to a geothermal site, dissolving many ores which have been trapped in the surrounding rock and then through cooling the ore precipitates into a solid and purified metal. Gold was formed in the Sierra Nevada inside the Smartville block while it was still underwater and it was later brought to the surface through tectonic movement. This formation process exposed many sites which were ideal for gold mining. The miners learned that placer deposits could be excavated in many ways. They also learned that hard-rock deposits were the original sources for the eroded ore that was washed into the placer deposits. Miners learned that the presence of granite and quartz indicated an ideal location for gold formation. Placer deposits were mined in many ways using panning, drift, and hydraulic mining methods. Panning was a way to mine placer deposits and the only tool used was a gold pan. Drift mining was used to extract gold from deep within the earth. Hydraulic mining is used to excavate ore-rich gravel from deep within the earth by blasting an exposed ore-rich bank of gravel with highly pressurized water. There are many different methods of gold mining specifically used on the gold deposits of the Sierra Region. These include heap leaching, open-pit mining, and extraction through the Cornish pump. Heap leaching was one of the first methods used in mining in which the ore was crushed and then drenched in cyanide to dissolve the gold out of the ore in order to refine it.
