我国大倾角、大采长煤层开采研究现状

大倾角、大采长煤层开采是当前我国部分矿区(特别是西部矿区)中大量实践且有着广泛应用前景的一种煤层开采技术。结合我国大倾角、大采长煤层开采发展现状,对大倾角、大采长煤层开采进行了研究,从机械化开采方法与变革、非机械化开采方法与变革、与大倾角煤层开采相关的其他研究等方面探讨了大倾角、大采长煤层开采发展前缘,介绍了大倾角、大采长煤层开采在我国的应用概况,最后指出解决大倾角煤层机械化开采技术难题应从系统研究大倾角煤层开采的矿山压力规律人手,研究大倾角煤层开采"R—S—F"系统稳定性是今后的研究重点,并提出了合理的对策。

Research and Extracting Status of Large Angle and Large Length Coal Seam in China

Long large mining-coal seam is part of China's current mining areas(especially in the western mining area) in practice and has a broad prospect of a coal mining technology.On basis of China's the status of steep and large mining coal mining development,and the research of long and large mining coal mining have been studied.The large mining-coal mining in China application has been introduced,from mechanized mining methods and changes in non-mechanized mining methods and changes,the inclination of the other ...
