中国有色金属工业总公司矿产地质研究院和辽宁有色地质勘探公司共同合作,于1986年6月完成了北京有色冶金设计研究院负责设计的铜录山露采边坡岩心定向钻探工程。同年10月提交了全部技术资料,获得了较好的经济枝术效果。施工区地层复杂,岩体破碎,给施工带来了很大困难。他们根据不同地质条件,采用不同型号的多点随钻定向仪器,使回次和进尺定向成功率分别达到75～81％和84～89％,岩心采取率大于95％,终孔时钻孔偏离设计靶点的距离达到了设计要求,按时提供了勘察技术报告及各项工程
China Nonferrous Metals Industry Corporation Institute of Mineral Geology and Liaoning Non-ferrous Geological Exploration Company to work together to complete in June 1986 the Beijing Nonferrous Metallurgical Design and Research Institute is responsible for the design of Tonglushan Lu mining slope directional drilling project. In the same year in October submitted all the technical information, access to a better economic results. The strata in the construction area are complex and the rock mass is broken, which brings great difficulties to the construction. According to different geological conditions, they use different types of multi-directional directional drilling instruments, so that the success rate of back-and-foot-in approaches are 75-81% and 84-89%, respectively, and core take-over rates are more than 95% Design target distance to meet the design requirements, provided on time survey of technical reports and various projects
