复杂地质条件下矿井瓦斯综合治理技术

Technique of Gas Harnessing Comprehensively in Coal Mine under Complex Geology Condition

霍州煤电集团矿区受活动的什林挠褶断裂带和霍山断裂带的影响,地质构造异常复杂。受其影响,李雅庄矿矿井瓦斯涌出异常,难有规律可寻,给瓦斯治理造成诸多困难。本文对矿井回采工作面在不同煤层附存条件下瓦斯涌出量大小、涌出来源和不同的涌出形式进行了分析,提出了针对性的瓦斯治理措施,对预防瓦斯积聚和瓦斯治理起到了积极作用。

Mining area of Huozhou coal electricity group company is under the influence of shaky fracture zone of shenlin deflection fold and Huoshan,geologic constitution is unusual complex, under the influence of it,gas gushing from Liyazhuang coal mine is abnormal,it is difficult to seek regulation,creats a lot of difficulty to harness gas. This text analyses size of amount of gas gushing, origin gushing and different form gushing under different seam to attach itself to stowage condition in coal mining face ,puts forward the measures to be aimed at harnessing gas,plays a positive role to prevent accumulating gas and harnessing gas.
