| 摘 要： | 由于煤矿自燃火灾的火源隐蔽,给灭火工作带来困难,因此,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,不仅速度快,而且还能够确定火区燃烧中心位置。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%。

| Abstract: | Coal fire makes a great loss of coal resources and a great destruction of ecological environment,and the fire extinguishing is very difficult because of the invisibility of fire sources.Consequently,a crucial thing of controlling the coal fire is to detect the coal fire areas and to determine the burning centers.Now a days,engineering exploration is expensive and remote senses techniques can only underline the bound of coal fire.In this paper a fast geophysical method is put forward,which can not only detect the coal fire area but determine the burning centers.Drilling results proves that the errors of calculated depths by the geophysical method is less than 20%. |
