摘要
阿刀亥煤矿CU2煤层属于急倾斜特厚煤层,煤层埋藏较深,瓦斯涌出大,属于高瓦斯矿井。为了保证回采过程中的安全,结合本煤层的瓦斯地质规律,提出了瓦斯治理对策,主要是针对开采分层的下部煤体的瓦斯进行预抽、顺槽斜交插帮钻孔、上隅角埋管抽放等方式,从源头上解决了工作面瓦斯超限的问题。
Adaohai coal mine CU2 coal seam belongs to steeply inclined thick coal seam,coalburied deep,gas emission,which belongs to the high gas mine. In order to ensure the safety in mining process,combined with the law of gas geology in the coal seam,and puts forward some countermeasures for the lower part of the coal gas control of main boby slicing the pre pumping,trough oblique inserted for drilling,upper corner buride drainage pipe etc.,from the source to solve the problem of face gas overrun.
