摘　　要： 镇沅县蛮晏煤矿属设计生产能力6万t/a,煤尘有爆炸危险性、煤层为Ⅱ类自燃。通过对其煤层自燃条件的分析,针对该煤矿从开拓开采方法、通风、监测监控和喷洒阻化剂4个方面提出了预防煤层自燃的防治措施,达到了预期的效果,为同类条件的矿井提供了借鉴。 The Manyan coal mine in Zhenyuan county, with the production of 60 kt / a, features with its coal dust easily to explode and its coal seam’s second - level spontaneous combustion. This article analy-ses the conditions of coal seam^s spontaneous combustion and discusses how to prevent it from four aspects as follows： exploring more mining methods; ventilation; monitoring and inspecting; spraying the retard-ers, which turns out to be effective and provides the reference for relevant studies.
