摘要
为解决818综采工作面地温偏高,采空区自燃危险性上升问题,通过对采空区自燃危险区域进行判定,分析高地温环境对采空区煤自燃的影响,制定防止采空区发生自燃危险的综合措施。实践结果表明,采取综合防治措施后,采空区内温度得到有效控制,煤层自然标志气体含量无明显增加,为8煤层的安全开采提供了有力保障。
In order to solve the problem that the ground temperature of 818 fully mechanized mining face is too high and the risk of spontaneous combustion in goaf increases, the influence of high ground temperature environment on spontaneous combustion in goaf is analyzed through judging the danger area of spontaneous combustion in goaf, and the comprehensive measures to prevent spontaneous combustion in goaf are formulated. The practical results show that the temperature in the goaf is effectively controlled and the natural gas content of coal seam does not increase obviously after taking comprehensive control measures, which provides a strong guarantee for the safe mining of the 8coal seam.
