摘要
在全球能源需求不断增长的背景下,各类型矿产资源的开采速度正在加快。然而随着开采深度的增加,高温热害问题逐渐凸显。高温热害问题不仅影响各类机械设备的正常运行,还对矿井安全生产构成了严重威胁。笔者以南方某硬岩铀矿井为例,分析了矿井热害问题的产生原因及影响;通过数值模拟等方法,深入研究了该矿井的围岩热物性参数、矿井地温场及深部热环境等,分析了该矿井目前存在的问题,并提出降温技术方案。
Against the background of growing global energy demand,the rate of extraction of various types of mineral resources is accelerating.However,with the increase of mining depth,the problem of high temperature and heat damage is gradually highlighted.The high temperature and heat damage not only affect the normal operation of various types of machinery and equipment,but also pose a serious threat to the safe production of the mine.The causes and effects of heat damage in mines were analyzed.At the same time,taking a hard rock uranium mine in the south of China as an example,through numerical simulation and other methods,the thermal and physical parameters of the surrounding rock of the mine,the geothermal field of the mine and the deep thermal environment were studied in depth,and on this basis,the existing problems of the mine were analysed,and the cooling technology was proposed.
