摘　　要：针对大倾角不等长工作面回采过程中容易出现的支架溜槽上窜下滑、倒架、咬架以及煤壁片帮、滚矸伤人等问题进行了现场实践,根据实践效果,提出了具体解决方法,切实有效解决了大倾角不等长工作面生产过程中的一些难题,保证了工作面的安全回采。This paper summed up some problems that are easy to appear in the process of mining the working face with big angle and unequal length, such as sliding of support chute, supports falling, supports collision,coal wall scraping and rolling of gaugue,and so on.According to these problems, the field practices were carried out,the concrete solutions were also put forward. The application of the solution has effectively solves some problems in the production process of the working face with large angle and unequal length, and effectively guarantees the safe mining of the working face.
