钻探工程是以机械方式破碎岩石的。古代是采用冲击钻进,其后逐渐发展以回转为主的钻进方法。近几十年来,国内外的探矿工作者根据动载荷比静压载荷能够更加有效破碎脆性岩石的原理以及为了充分发挥冲洗液的能量作用,又研究成功液动冲击迴转钻进 Drilling works are mechanical rock crushing. Ancient is the use of impact drilling, and later gradually developed to swing-based drilling method. In recent decades, the prospecting workers at home and abroad based on the dynamic load than the hydrostatic load can more effectively break the brittle rock principle and in order to give full play to the energy of the flushing fluid, but also the successful study of hydraulic impact rotary drilling
