Strengthening Research about Hole Hydrautic Mining Technology of Mineral Resouces and Widening Innovation Development Space of Exploration Engineering

Abstract:

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 principle 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. It is suggested to strengthen the research on this technology to broaden the innovation development and service space of exploration engineering in China.
