综放工作面综合防治自然发火

开滦唐山矿业公司为Ⅲ级自然发火矿井，特别是综放工作面开采给防治自然发火工作带来很大困难。通过对T1491工作面发火隐患情况进行分析，找到了低温氧化、系统漏风等因素是造成煤层自然氧化的原因，采取了调整采区通风系统、阻化剂防火、喷浆堵漏风、灌浆、均压防灭火等综合治理措施，杜绝了煤层自然发火事故的发生，确保了矿井的安全生产。

Syntherically Prevention of Spontaneous Fire of Surface

Tangshan mining industry of Kailuan is ranked three spontaneous fire pit.Especially the exploitation of race bring forth tremendous difficulty to the work of preventing the natural fire.By the analysis of potential fire condition of T1491 face,we find that the low temperatore oxidation system leak out and so on are the causes of coal seam oxidation,we use the overall harness measure such as the adjusting the ventilation system of the working area,using the obstructer to prevent fire,using quniting to stop leaking, even the pressure to prevent or wring out the fire to diminish the occurrence of natural fire accident to insure the safe production of pits.
