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.

关键词: 现今地温场, 地温梯度, 特征, 高温热害, 淮北煤田

Abstract:

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.

Key words: present geo-temperature field, geo-temperature gradient, characteristics, thermal damage, Huaibei coalfield
