察哈素煤矿煤炭自燃影响因素及防灭火技术研究

摘要

对煤炭自燃的原因进行了内因、外因两个角度的讨论,通过查阅相关资料以及取煤样进行含水量变化实验的方式对察哈素煤矿31303工作面的煤质进行了全面的分析,并结合察哈素煤矿31303工作面实际工作情况,提出了包括预测预报、通风系统优化、加强管理等在内的综合防灭火方案.%The causes of spontaneous combustion in coal roadway are discussed from two aspects: internal and external factors.The coal quality of 31303 working face in Chahasu coal mine is analyzed comprehensively by referring to the relevant data and taking water samples to change the water content.And combined with the practical work of 31303 working face in Chahasu coal mine,the paper puts forward a comprehensive fire prevention and fire prevention plan including forecasting and forecasting,ventilation system optimization and strengthening management.
