摘要
淮北煤田是中国东部主要的煤炭生产基地之一.通过分析淮北煤田孙疃-赵集2个新勘探矿区中测温数据资料,绘制出了研究区主采煤层在后期开采中可能产生高温热害的分布图.研究表明:孙疃-赵集勘探区现今地温梯度分布范围介于1.7～3.6℃/hm,平均现今地温梯度约为2.68℃/hm,3个主采煤层的高温热害区表现出了东高西低的特点.
Huaibei coalfield is an important base of energy sources in East China.On the basis of analyses of temperature data in Suntuan-Zhaoji exploration area of Huaibei coalfield,thermal damage zones are mapped out in the main mining coal beds in that area.The results indicate that the geothermal gradient values range from 1.7℃/hm to 3.6℃/hm in Suntuan-Zhaoji geothermal exploration area.The average present geothermal gradient value is about 2.68℃/hm in the area.Thermal damage zones in the three main mining coal beds are high in the east part of the area and low in the west part.
