摘　　要：在各种采煤方法中,综采具有既安全又高效的优点,但在开采大倾角煤层时采用综采技术的难度大,在开采复杂地质条件下大倾角煤层时采用综采技术的难度更大。四川省广能集团绿水洞煤矿针对开采复杂地质条件下大倾角煤层时采用综采技术的问题进行研究并采取相应的措施,提高了采煤工作面的产量,取得良好的经济效益和社会效益。Fully mechanized coal mining has the advantage of safety and high efficieney among various kinds of coal - mining system, but it is more dimcult to adopt fully mechanized coal - mining technology when a coal seam with large dip angle is to be extracted, even it is much more difficult to adopt fully mechanized coal- mining technology when a coal seam with large dip angle and under complicated geologic conditions is to be extracted. To aim at the adoption of the fully mechanized coal - mining technology in extraction of a coal seam with large dip angle and under complicated geologic conditions, study was conducted and relevant measures were taken by Lushuidong Coal Mine of Sichuan Guangneng Group, this thus increased the output of the working face and gained better economic and social benefits.
