梨树煤矿瓦斯地质特征与防治瓦斯研究

Research on Gas Geologic Characteristics and Prevention and Cure of Gas in Lishu Coal Mine

鸡西矿业集团公司梨树煤矿由于地质条件的变化引起矿井瓦斯涌出不均衡。该矿根据区域瓦斯涌出实际,采用合理分配风量、高抽巷、仰角钻孔、本层钻孔、边掘边抽及煤层注水等方法,对矿井瓦斯进行综合治理,取得了良好的效果,同时也为今后的矿井开采积累了经验。

The gas emission isn t balanced because of the change of geologic conditions in Lishu Coal Mine in Jixi Mining Indusrty Group Comp.According to the actual conditions of district gas emission,some methods were adopted,such as reasonable distribution of air flow,high drainage roadways,elevation drilling,drilling in self coal seam,while excavation and extraction,and coal injection ctc.The integrated management was in progress in the coal mine.The good effects were obtained.The expericence was accumulated for m...
