复杂型急倾斜煤层的开采技术

Technical Research on Complicated and Steeply Inclined Coal

青山煤矿地质条件复杂、煤层倾角大,属急倾斜煤层,且煤层厚度不一、并伴有自燃、瓦斯与水突出等威胁,属于典型的复杂型急倾斜煤层。由于地质条件和赋存情况的差异,复杂型急倾斜煤层的开采方法与赋存条件好的缓倾斜煤层有着诸多的区别。以青山煤矿为依托,简述了复杂型急倾斜煤层的开采技术,为我国其它类似条件的煤层开采提供了参考。

The coal of Qingshan coal mine is complicated and steeply inclined coal, gas and grime popping out and the thickness of the coal change clearly. The caving technique for the complicated coal is difierent from the general coal. According to the practice of the Qingshan coal mine, the technique for caving the complicated and steeply inclined was introduced.
