摘　　要：通过对薛村矿综放工作面采空区自燃火灾指标气体及温度的检测,得出了薛村矿煤炭自然规律,并提出了预防自然发火的关键技术。认为合理配风,均压堵漏,快速推进,减少丢煤,采空区雾化阻化,采空区注浆、注CO2气体等是防止采空区自然发火的有效措施。The regularities of coal spontaneous combustion in Xuecun Coal Mine becomes known based on tests of the spontaneous combustion indicator gases and temperatures in the gob areas of the top coal caving longwall faces of this Mine.Also on the basis of these,a set of key technology is proposed aimed at fire prevention.According to the author,a rationalized supply of ventilating air flow,pressure balance for blocking air leakage,fast moving of coal face,minimizing coal left over in the gob,water mist and retardant spraying in gob area,grouting in gob area and injection of CO2 in gob area are effective measures to prevent spontaneous combustion in gob areas.
