【摘要】 应用矿压理论、气体爆炸理论、自然发火及火风压理论对回采工作面采空区发生爆炸的原因进行了分析,详细地阐述了爆炸产生的过程,提出了采空区爆炸机理的3个新观点:(1)煤炭自然发火是导致爆炸的根本原因(唯一火源因素);(2)煤炭堆积自然发火正反馈是导致煤炭自燃的主要原因;(3)火风压是形成爆炸条件的动力源.建立了煤炭自燃时气体流动结构图,这些新观点全面地解释了回采工作面采空区CO或沼气发生爆炸的机理,为今后防治采空区爆炸的产生提供了科学的理论依据.更多还原

【Abstract】 This paper analyzed the cause of explode in working face with groundpressure,gases explode,spontancous combustion,or firepressure theory and exprounded detailed the explode process.It gave three new standpoints about mechanism of explode in working face as follow: (1)The coal combustion is lead to explode by only fire souce; (2) The coal stacking combustion positive feedback is the main reason to lead to the coal combustion; (3)The firepresure is power souce formed explode condition.It will provide scientific theoretical basis for preventing explode in waste in the future.更多还原
