摘要
钻孔水力采矿是钻探工程在采矿工程中的一种直用,是一个重要发展方向,具有拓宽创新意义。本文介绍了钻孔水力采矿的工作原理和工艺过程;讨论了石油喷射钻井射流和钻头的水力参数;探讨了钻孔水力采矿时破碎矿石的孔内射流碎岩器具及其结构参数;提出了有关改进这种技术的方法和手段的几点建议。钻孔水力采矿由于工程效益好、安全系数高和生态环境保护好等优点在国外一直在研究和使用。建议我国加强这方面的研究,以拓宽探矿工程的创新发展和服务空间。
Hole hydraulic mining technology of mineral resources （HHMTMR） is a kind of application of drilling engineering in mining industry, and is an important development direction with innovation significance. In this article, the work princi- ple and technological process of HHMMR are introduced, hydraulic parameters of jet stream and drill bit used in petroleum jet drilling are discussed, jet perforator used for cutting ore and rock in the hole bottom and its design parameters are also discussed and some suggestions about means and methods for improving this technology are put forward. Because of the advantages of good engineering returns, high safety factor and good ecological environment protection, HHMMR has being researched on and applied in foreign countries, for example in USA and Russia. h is suggested to strengthen the research on this technology to broaden the innovation development and service space of exploration engineering in China.
