本文以国内外大量的生产实践资料充分地论证了水力采煤是实现赋存复杂的急倾斜厚煤层采煤机械化的有效途径之一。同时,文章还着重针对解决在高沼气煤层条件下采用水采时的通风安全问题及在厚煤层开采时如何减少煤炭损失等问题进行了较深入的分析,并提出了一系列技术措施。
In this paper, a large number of domestic and international production practice data fully demonstrate that hydraulic coal mining is one of the effective ways to realize coal mining mechanization in complicated and steep thick coal seam. At the same time, the article also focuses on solving the problems of ventilation safety when using water mining in high biogas coal seam and how to reduce coal loss when mining thick coal seams, and puts forward a series of technical measures.
