摘要
车家庄煤业有限公司井田范围内,存在多起因历史小煤窑开采及煤层浅部赋存导致的高温区域,严重威胁煤矿安全生产。为精准定位高温异常区并确定其边界,本文利用高精度磁力仪,对车家庄煤业二采区北和三采区进行了磁法探测高温异常区域勘探。探测结果表明,二采区北区块磁场异常ΔT值变化相对稍小,无高温异常区,三采区磁场异常ΔT值变化明显,从-168.28~315.90 nT,根据探测数据,在三采区共圈定7处高温异常区,总面积达79910.02 m^(2),车家庄煤业磁法探测有效识别了煤层自燃引起的磁性异常,为车家庄煤矿火区治理提供科学依据。
There are multiple high-temperature areas within the mining area of Chejiazhuang Coal Industry Co.,Ltd.caused by historical small coal mine mining and shallow coal seam occurrence,which seriously threaten the safety production of coal mines.In order to accurately locate the high-temperature anomaly area and determine its boundary,this paper used a high-precision magnetometer to conduct magnetic exploration of the high-temperature anomaly area in the north and third mining areas of Chejiazhuang Coal Industry.The detection results show that theΔT value of the magnetic field anomaly in the northern block of the second mining area is relatively small,and there is no high temperature anomaly area.TheΔT value of the magnetic field anomaly in the third mining area changes significantly,from-168.28 nT to 315.90 nT.According to the detection data,a total of 7 high temperature anomaly areas were delineated in the third mining area,with a total area of 79910.02 m^(2).The magnetic method detection of Chejiazhuang Coal Industry effectively identified the magnetic anomaly caused by coal seam spontaneous combustion,providing a scientific basis for the management of the fire area in Chejiazhuang Coal Mine.
