摘要
结合马泰壕煤矿首采工作面实际情况,构建了工作面采空区自燃"三带"取样系统进行取样分析。参考氧气、一氧化碳变化规律,对采空区自燃危险性区域进行了划分。建立数值模型,利用数值模拟软件进行验证,确定了工作面推进速度及防灭火重点区域,为工作面采空区的防灭火工作奠定了基础。
Combining with the actual situation of the first mining face of Mataihao Coal Mine , the" Three Zone" sampling system for spontaneous combustion in working face was constructed for sampling and analysis .According to the change rule of oxygen and carbon monoxide , the spontaneous combustion danger area of goaf was divided . Finally , the model was established , and the numerical simulation software was used to verify the speed of the working face and the key areas of fire prevention and extinguishing , which indicates the direction of the fire prevention and extinguishing work in the goaf area of the working face .
