摘　　要：以具体的下分层采面为研究对象,重点从探测采面通风系统的压能分布、煤体漏风通道及漏风量、煤壁温度及高温气体涌出点,以及从监测气样组分入手,并结合实验室煤体常温氧化试验结果,研究经济、合理的综合防灭火措施。研究结果表明,上述探测途径能够准确地确定出煤炭自然发火防控的重点区域,经济有效的防灭火方法就是依据各种监测结果对普查出的重点区域进行喷浆封闭。Taking the coal lower layered face as research object, economic, reasonable comprehensive fire prevention measures need to be considered from the factors including detecting pressure energy distribution of ventilation system, coal body temperature, air leakage channels and air leakage amount, and high temperature gas emission points from monitoring gas samples component and laboratory test results of coal oxidation at room temperature. Research results show that the prevention approach pointed out in this paper can accurate- ly determine the key area of prevention and control of spontaneous combustion of coal. An economical and effective method is grouting the key tunnel or coal body based on the monitorlng data.
