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 concrete under the stratified mining face as the research object, the paper focuses on the distribution of pressure energy in the ventilation system of the coal face, the air leakage path of the coal body and air leakage, the coal wall temperature and the high temperature gas emission point, and the components of the monitoring gas sample , And combined with the laboratory test results of normal temperature oxidation of coal to study the economic and rational comprehensive fire prevention measures. The results show that the above detection methods can accurately identify the key areas of coal spontaneous combustion prevention and control, cost-effective fire prevention and extinguishing method is based on a variety of monitoring results of the key areas of the general survey of jet sealing.
