矿井反风是煤矿防止火灾事故扩大的非常措施,我国《煤矿安全规程》对此作了严格的规定。以往说的矿井反风主要指在矿井进风井口、井底车场、主要进风大巷等处发生重大火灾或爆炸事故时,为减少生命财产损失而进行的全矿井反风。但从实用价值看,在生产矿井尤其是瓦斯突出矿井,容易发生灾变的地点并非只发生在主进风系统,而多数是发生在采掘工作面。在后者情况下,如果进行全矿井反风显然是不适宜的。且全矿井反风有时还会引起下层工作面的自燃。根据我矿沼气涌出量大,煤层有自燃倾向、煤尘有 Anti-wind mine is the coal mine to prevent the expansion of fire accidents is an extraordinary measure, China’s “Coal Mine Safety Regulations,” which made strict rules. In the past, the anti-wind mine mainly refers to the whole mine anti-wind to reduce the loss of life and property when a major fire or explosion occurs at the intake wellhead, the bottom of a well, the main wind tunnel, However, from the practical value, in the production of mines, especially gas outburst mines, prone to catastrophe occurred not only in the main air intake system, and most occurred in the mining face. In the latter case, it is clearly not appropriate to carry out mine-full blasting. And the whole mine sometimes lead to spontaneous combustion of the lower face. According to my mine gas emissions, coal seam spontaneous tendency, there is coal dust
