高瓦斯矿井瓦斯抽采方法研究与应用

The Gas Drainage Research and Application in High Gas Mine

瓦斯是煤矿生产事故的根源,同时也是一种清洁的绿色能源,在煤矿开采过程中,合理而有计划地抽采并综合利用瓦斯,一方面降低和减少了瓦斯事故的发生,另一方面减少了能源浪费和环境污染。本文通过分析煤炭开采时瓦斯的分布运移规律得出瓦斯抽采原则和抽采方法,通过在王坪煤矿本煤层预抽、邻近层裂隙带抽采、掘进工作面抽采和全封闭采空区抽采四种方法相结合的工程实践,抽采效果显著,在提高回采安全性的同时,经济效益也十分显著。

The gas is the root cause of coal mine accidents, and at the same time it is also a kind of clean green energy. In the process of coal mining, reasonable and systematic extraction and comprehensive utilization of gas, on the one hand, can reduce the gas accidents, on the other hand can reduce the energy waste and environmental pollution. This article through the analysis of the distribution of coal mining in the gas migration law principles and extraction method, it is concluded that the gas extraction in Wang-ping mine company of this coal seam drainage,adjacent layer fissure zone extraction, extraction of drivage face and fully enclosed mined-out area extraction from four ways of combining the engineering practice, extraction effect is remarkable, in improving the safety of mining at the same time, the economic benefit is significant.
