摘要
根据新集一矿C13煤131303综放工作面实际情况,通过实测和模拟实验,对C13煤层综采放顶煤工作面采空区自燃"三带"分布进行了测定,结合采空区煤炭自燃理论,得出"三带"分布规律和各带的数值范围,计算了工作面推进度,同时确定了工作面防灭火技术参数,为防灭火管理提供了科学依据。
According to the actual situation of C13 coal in131303 fully mechanized caving face, through the observation and simulation experiment, the C13 coal seam fully mechanized top coal caving working face goaf spontaneous combustion ＂three zones＂ distribution were measured, combined with the theory of spontaneous combustion of coal in goaf, the＂three zones＂distribution and the numerical range, calculated the mining speed , while determining the technical parameters of working face of ifre prevention, and provided the scientiifc basis for the ifre prevention management.
