我国矿井降温技术研究工作处于初期阶段。淮南九龙岗矿、北票台吉矿、浙江长广煤炭公司7号井、辽宁红阳三井和潘集矿区几个井已经和将要遇到井下高温威胁,引起了人们的重视。南非、西德、苏联等国家深井高温问题比较严重,研究工作开展得较早,借鉴他们的研究成果,结合我国国情对防治矿井热害是有益的。
China’s mine cooling technology research is in its infancy. Several wells in Huainan Jiulonggang Mine, Beipiao Taiji Mine, Zhejiang Changguang Coal Company No. 7 Well, Liaoning Hongyang Sanjing Mine and Panji Mine Area have encountered and are about to encounter the threat of underground heat and have aroused people’s attention. South Africa, West Germany, the Soviet Union and other countries more serious problems of deep well temperature, research carried out earlier, learn from their research results, combined with China’s national conditions on the prevention and treatment of mine thermal damage is beneficial.
