摘要
随着煤层开采深度的不断增大,地热危害越来越严重,掌握矿井地温分布规律势在必行。通过收集矿区36个钻孔井温测井资料3号煤层的温度并做等值线图,可以看出在井田西南部S8、S15和S18号三个钻孔附近最下部可采煤层温度均超过国家规定的一级热害标准(31℃)。在实际工作中根据测井资料所划分出的地温分布规律及热害范围可更加准确地指导煤矿安全生产。
With the increasing of coal seam mining depth, geothermal hazards are becoming more and more serious, it is imperative to master the distribution of underground temperature. By collecting the temperature of the coal bed at no.3 coal seam of 36 boreholes in all the mining areas, the contour map is made, and it can be seen from the map in south west of the field near the S8, S15 and S18 boreholes, the temperature in the lowermost minable seam is higher than the standards set by the state（31℃）.In practice, the distribution of ground temperature and the range of thermal damage based on logging data can guide coal mine safety production more accurately.
