摘要:
采空区瓦斯抽采与煤自燃防控相互影响,工作面配风量、抽采负压和高抽巷位置等参数影响了采空区自燃危险区域范围。通过在天池矿301工作面采空区内布置监测点并分析气体变化,确定了采空区瓦斯与煤自燃灾害协同防控的关键区域。结合瓦斯抽采和采空区煤自燃的耦合作用机制,采用数值模拟和现场实测方法确定了工作面配风量、高抽巷位置以及推进度等主要关键参数。研究结果表明:当工作面配风量为3 000~3 500 m3/min,推进度为1.39~6.84 m/d,高抽巷与顶板垂距为30 m,与回风巷平距为25 m,抽采负压为14.5~17.5 kPa时,既能确保抽采效果,也可有效地防止采空区煤自燃。
Abstract:
It is interacted with gas drainage and prevention and control of coal spontaneous combustion in gob.Coal spontaneous combustion danger zone is influenced by the parameters such as air flow,suction drainage pressure and position of high extraction roadway.Taking Tianchi coal mine 301 working face as case,through arranged monitoring points in gob and analyzed gas concentration,the key zone of the coordination prevention was determined between the disaster of methane and coal spontaneous combustion.Combined gas extraction and coal spontaneous combustion coupling mechanism,the main technical parameters including air volume,position of high drainage roadway and mining rate were determined by the mean of numerical simulation and field measurement.The property parameters such as air volume(3 000~3 500 m3/min),advance speed(1.39~6.84 m/d),distance between drainage roadway and roof(30 m),distance between drainage roadway and air return way(25 m)and drainage pressure(14.5~17.5 kPa)could not only insure drainage effect,but also prevent the coal spontaneous combustion effectively in gob.
