摘要
地下煤火燃烧煤炭资源的同时,产生大量的热量,上覆岩层由烘烤烧变到熔融。煤火引起上覆岩层塌陷,地面形成裂隙,烧变岩内部孔隙变大,裂隙、孔隙则为煤火进一步发展提供了O2通道和散热通道。燃烧区后方,煤层燃烧殆尽、热量散失、温度降低、熔融状岩石冷却,形成了各种不同结构、构造的烧变岩区。对红外热像仪在煤矿隐蔽火源探测的应用进行了分析。
The massive heat produced by the combustion of coal resources caused by underground coal fire can burn the overlying strata to melt. Coal fire can cause collapse of the overburden, formation of the ground fissure, and larger internal pore of burnt rock. And the fracture and pore can offer channel of 02 and heat radiation for the further development of coal fire. At the rear combustion area, coal seam is burned out, heat loses, temperature abates, and molten rock cools and forms burnt rocks area with a variety of different structure and constitution. The Application of thermal infrared imager in hidden fire detection of coal mine is analyzed.
