Research on method of reducing waste hole rate of water bearing step drilling in Fushun East Open-pit Mine
JIANG Hanlei
Abstract：In order to reduce the waste hole rate of drilling rigs,save operating costs,improve the blasting rate per meter,and optimize the overall technical and economic effects of drilling and blasting projects,the production technicians of East Open-pit Mine sort out the reasons for the high waste hole rate and collapse during drilling operations,summarize the root cause of the high waste hole rate,and successfully solve the technical problems of high waste hole rate,low blasting rate,and low cost and efficiency of drilling and blasting projects by optimizing the drainage system,changing the excavation and depth reduction process,refining process connections,implementing management measures and other engineering,process and management methods.
