高瓦斯矿井自燃煤层开采设计中应注意的问题

Matters for Attention in Extraction Design of Seams with Spontaneous Combustion in High Gassy Mine

在高瓦斯矿井自燃煤层开采设计中应注意推广应用无煤柱开采,确定合理的开拓布置、开采顺序和开采方法;建立与矿井相适应的瓦斯抽放系统,确定合理的通风、安全监测监控系统和防灭火灌洒浆系统,对煤层自然发火采取综合性防治措施。

Attention should be paid to the popularization and application in extraction design of seams with spontaneous combustion in high gassy mine, the determination of reasonable development layout and the mining sequence and method. It is necessary to set up appropriate gas drainage system, determine reasonable ventilation and safety monitoring system and fire prevention and control system by grouting, and take comprehensive control measures for coal seams with spontaneous combustion.
