摘要
随着中国矿井开采深度的不断增加,矿井热害问题日趋严重。通过分析中国主要聚煤盆地1 000 m、2 000 m的地温分布规律,确定中国的热害矿井主要分布在东部地区以及西部四川等省市的个别地区,并结合岩石的结构和岩性、构造特征、岩浆岩、地下水的深热循环及采掘活动中机电设备放热和煤层氧化放热等因素,认为矿井热害主要由岩性、构造特征、地下水活动情况以及采矿工程活动单独作用或者共同作用造成。
With the increase of mining depth in China, the heat damage of mines becomes more and more seri- ous. By analyzing the distribution regularities of ground temperature about 1 000 m and 2 000 m of major coal basin in China, determines that the heat damage mines in China primarily locate in east regions and individual regions of west such as Sichuan province. And combines the factors such as structure and lithology of rock, structure characteristics, magmatic rock, deep and thermal cycling of underground water and heat release of electromechanical equipment and coal seam oxidation in mining process and so on. Considers that mine heat damage mainly caused by lithology, strue- ture characteristics, ground water activity and single or combined action of mining engineering activities.
