龙东煤矿7135工作面发火规律的研究

Study on the Spontaneous Combustion Discipline of Face7135 in Longdong Mine

龙东煤矿7135工作面是龙东煤矿一个较短的综合放顶开采工作面,该工作面断层较多,煤层自燃倾向性较高,开采该煤层发火危险性大,为了确保该工作面安全回采,必须测定煤炭低温氧化过程的基础参数与采空区遗煤氧化三带宽度,掌握该工作面开采过程中采空区煤炭氧化特点及发火的规律性,确定煤炭自燃早期预测手段,制定定综合防灭火措施,确保工作面安全回采。

Face7135 of Longdong Mine is a fully -mechanized roof- coal caving face, which includes many faults and has stronger dendency of spontaneous combustion. To ensure extraction safely, the basic parmeters of coal oxidation process in low temperature and the three bands of the residual coal in goaf must be measured, and the oxidation feature and combustion regularity of the residual coal must be grasped during extraction, as well as the early prediction methods on spontaneous combustion. So the comprehensive fire - extinguishing measures can be used to ensure the extraction safety.
