井下高温与岩石高压是深井开发中的两大难题。前者引起中暑事故,危害矿工保健;后者导致岩爆,威协矿井安全。由于现代岩石力学的发展与应用,岩爆造成的灾害已逐渐减少;而井下热问题已成为矿井经济开采深度的决定因素。井下热源不外物理、化学两大类。物理热源有地热、地下热水、空气压缩热、岩层沉降热和机械热;化学热源包括氧化反应热、坑木腐烂发热、爆破热、人体代谢生成 Downhole temperature and rock pressure are two major problems in deep well development. The former causes heatstroke accident, endanger miners health; the latter lead to rock burst, Wei Association mine safety. Due to the development and application of modern rock mechanics, the disasters caused by rockburst have been gradually reduced; and the underground heat problem has become the determining factor of mine economic exploitation depth. However, underground heat source physics, chemistry two categories. The physical heat sources are geothermal, underground hot water, air compression heat, rock subsidence and mechanical heat; the chemical heat source includes oxidation reaction heat, rotting crater wood, blasting heat, body metabolism
