一、前言 煤炭自燃发火是煤矿生产中主要灾害之一,建国以来在党和国家的关怀下,广泛地采用了黄泥灌浆的消防火技术,取得了很好的效果。近年来采用的惰性气体和正在采用的均压防火方法,在防火工作中也取得了一定效果。 但是由于我国煤炭工业迅速发展,各地区条件不同,现有的防火方法已满足不了煤矿生产的要求。根据煤炭部的指示精神,为了研究新的经济合理的防火方法,使防火技术成龙配套,保证煤炭工业的大力发展,我
I. Preface Spontaneous combustion of coal is one of the major disasters in the production of coal mines. Since the founding of the People’s Republic of China, the Fire Fire Technology of Yellow mud grouting has been widely adopted under the care of the party and the state and achieved very good results.
