摘　　要：通过对大店沟韧性剪切带蚀变型金矿床多条平行金矿体空间状态以及生产探矿过程中钻机的应用分析,从技术、成本、效益三方面分析研究,推行“以钻代坑、坑钻结合”的探采理念,并结合KY-150钻机优点,认为KY-150钻机在大店沟金矿生产探矿中具有重要作用,在控制矿体形态的基础上,降低了探矿成本,提高了矿山企业的经济效益。Through the analysis of the spatial state of multiple parallel gold ore bodies in the ductile shear zone alteration type gold deposit in Dadiangou and the application of drilling rigs in the production and exploration process,the exploration and mining concept of"replacing pits with drilling and combining them with drilling"is promoted from three aspects of technology,cost,and benefit.Combined with the advantages of the KY-150 drilling rig,it is believed that the KY-150 drilling rig plays an important role in the production and exploration of Dadiangou gold deposit.On the basis of controlling the shape of the ore body,Reduced exploration costs and improved economic benefits for mining enterprises.
