近水平远距离下保护层开采瓦斯治理

Gas control of protective coat mining under flat and long-distance

介绍了潘一矿采用近水平远距离开采下伏弱突出煤层保护层,达到对突出煤层13—1的卸压;通过采取连续抽采,降低或消除13—1煤层的瓦斯含量和突出危险性,实现安全快速高效的掘进。

Flat and long-distance mining was used to mine underlying low burst coal protective coat, which released the pressure of 13-1 coal bed. Through pulling out gas continuously, the gas quantity was reduced and the gas burst of 13-1 coal bed was eliminated, and safe high-speed driving and high efficiency were realized.
