基于O_2和CO浓度综合划定采空区“三带”

Dividing three zones based on the concentration of O_2 and CO

采用束管监测方法,在采空区后溜子处布置探测点,测定指标气体,详细分析了大佛寺40106工作面采空区O2和CO的实际分布情况,指出了采用O2和CO浓度综合划定采空区"三带"的方法,并基于此提出了采用MIN～MAX优化的方式对采空区"三带"进行了划分,并推导计算出了工作面的极限推进速度,有效指导了大佛寺煤矿40106工作面的防灭火工作.

In this paper, index gases is tested through setting probe points along the back chute in the goaf with the method of monitoring of tube of flux. Through detailed anglicizing of 40106 working face, this paper proposes to use the method of concentration of CO and 02 to divide three zones. Based on this theory, this paper suggests using the method of MIN - MAX to divide spontaneous combustion zone, and elicit and calculate the speed limit of face, which guides the fire control working of 40106 faces effectively.
