【摘要】 煤矿自燃火灾的火源隐蔽,给灭火工作带来困难,控制煤田自燃火灾的关键是准确探测火区范围及燃烧中心,为灭火工作提供依据。采用物探方法进行火区探测,具有速度快,能够确定火区燃烧中心位置的优点。钻探验证结果表明,依靠磁法确定火区着火点深度误差小于20%。更多还原

【Abstract】 The coal mine spontaneous combustion fire’s fire hazard hiding,brings the difficulty for the fire fighting work,the control coal field spontaneous combustion fire’s key is the accurate survey fire area scope and the combustion center,provides the basis for the fire fighting work.Uses the physical prospecting method to carry on the fire area survey,has the speed to be quick,can determine the fire area combustion central place the merit.The drilling confirmation result indicated that depends upon the magnetic method to determine the fire area kindling point depth error is smaller than 20%.更多还原
