This study seeks to address the problems of major geo environmental hazards caused by high intensive coal mining in China s western eco environment frangible area including strong mining pressure surface subsidence soil and water loss and land desertification Using the high intensive mining at the Xiao jihan Coal Mine this paper investigates the compaction
The total value of the deal is around $200mn Geo said The deal will enable it to become one of Indonesia s largest coal producers it added Geo s coal output declined on the year during January June because of a lower production quota Its coal output during January June stood at t down by 29pc from t in the same period a year
Abstract Different from the shallow coal seam in deep mining the dynamic response of overlying rock has changed significantly due to the high in situ stresses and complex geological conditions The frequent occurrence of strong mine earthquakes seriously restricts the safe and efficient mining of deep coal resources This paper investigates the distribution and
The data shows that in India the open cast coal mining has dictate very much of % nevertheless only % are underground mines Apart from India 60% of the other countries have their underground coal extraction In India the coal production is continuously declining due to the heavy extraction of coal on near surface by open cast mining
