林华煤矿瓦斯抽采效果评价体系研究

Research on Evaluation System of Effect of Coal Mine Gas Drainage in Linhua Mine

以瓦斯抽采为主要目的以及《防治煤与瓦斯突出规定》、《煤矿瓦斯抽采基本指标》、《煤矿安全规程》等规定为依据,以残余瓦斯含量、残余瓦斯压力、K1值、Smax值、回风流瓦斯浓度、抽采率为指标,创建瓦斯抽采效果评价体系,并对林华矿井20912回风巷320~780 m段瓦斯抽采效果进行了评价,对煤矿瓦斯抽采具有重要意义。

Takes the main purpose of gas drainage and 'Coal and Gas Outburst Prevention Regulations', 'The Basic Indexes of Mining Coal Gas Pumping', 'Coal Mine Safety Regulations' and other regulations as the basis, and residual gas content, residual gas pressure, K1 value, Smax values,back romantic gas concentration, extraction rate as the index to create the evaluation system of the effect of gas drainage, and evaluates gas drainage effect of 320 ~780 m section of 20912 return airway in Linhua mine. It is very important to coal mine gas drainage.
