摘要: 通过收集整理矿井内地温资料及井下采样分析测试岩石热物理参数,利用基于有限元的Comsol Multiphysics数值模拟,分析主采区的地温分布特征及致热因素,并将实测温孔与数值模拟对比验证,研究许疃煤矿地温分布规律及其影响因素。同时计算获取研究区内大地热流值,绘制矿井热害影响程度分区图,预测受热害影响的范围,为煤矿下一步的热害防治提供有针对性的对策。

关键词: 地温分布规律, 地热流值, 矿井热害

Abstract: Abstract: The paper analyzes the geothermal data and tests the sampling rock thermal physical parameters in the mine, the Comsol Multiphysics numerical simulation based on finite element analyzes the geothermal temperature distribution characteristics and heating factors,and makes a verification of actual temperature hole and numerical simulation to study the geo-temperature distribution law of Xutuan Coal Mine and its influencing factors in the main mining area. At the same time, it calculates and obtains the geothermal flow value in the study area, draws a zoning map of the mine's heat impact degree, predicts the range affected by the heat hazard, and provides targeted measures for coal mine heat hazard prevention.
