在探矿工程领域中,不断提高钻探效率,降低钻探成本,多快好省地为地质找矿服务,一直是探矿工作者努力奋斗的目标.近十多年来,我国钻探技术发生了很大的变化,金刚石钻探、绳索取心钻探、冲击回转钻探等新工艺、新技术、新方法的应用,降低了钻探成本,减轻了工人的体力劳动强度,提高了地质效果,加快了找矿速度.本文将介绍钻探技术中的一枝新秀——不提钻换钻头钻探. In the field of prospecting engineering, continuous improvement of drilling efficiency, reduction of drilling costs, and faster and more economical geology prospecting service have always been the goal of prospecting workers’ hard work. For more than a decade, great progress has been made in drilling technology in our country The application of new techniques, new techniques and new methods such as diamond drilling, diamond core drilling, rope coring drilling and impact rotary drilling reduces the drilling cost, reduces the labor intensity of workers, improves the geological effect and accelerates the prospecting speed. Will introduce a rookie in drilling technology - do not mention drilling for bit drilling.
