预防矿内火灾的方法很多,有一般性技术措施和专门技术措施.本讲仅就一些采矿技术条件(开拓布置,开采方等)措施,通风措施以及防火手段和方法中的防火门,采后封闭和阻化剂等作些简单介绍.至于黄泥灌浆法,均压通风法防灭火将在第六、八讲中作专门介绍.一、开拓方式的选择及采区的合理布置在开采有自燃发火煤层的矿井开拓方式和采准巷道布置应以少留煤柱,少切割煤层为原则.因此,集中运输大巷和总回风道应布置在岩层内或无自燃发火的煤层内.倘若是将其布置在自燃发火煤层内,则必须砌碹或锚喷.碹后的空隙和冒落处,必须用不自燃性材料充填密实,不得漏风.
There are many ways to prevent mine fires, there are general technical measures and specialized technical measures.This talk only on some mining technology conditions (development layout, mining side, etc.) measures, ventilation measures and fire prevention methods and methods of fire doors, post-harvest Closed and resistance agent for some simple introduction.As for the yellow mud grouting, pressure equalizing ventilation fire prevention will be introduced in the sixth, eight for a special introduction.First, the way to explore and the rational selection of the mining area in the mining Spontaneous combustion seam coal mine development and mining approach should be arranged less coal pillar, less cutting seam principle. Therefore, the central transport lane and the total return duct should be arranged in the rock or spontaneous combustion coal seam. Is to be arranged in spontaneous combustion of coal seam, you must pray or anchor spray pound after the gap and the caverns must be filled with non-pyrophoric material dense, shall not be air leakage.
