| Abstract: | The scraper drift in mining process of Huili lead and zinc stock Co.Ltd is easy to collapse which causes more secondary supports and higher supporting cost.The composite supporting system of shotcrete-bolt and monolithic concreting supporting is proposed to resolve the difficult problem of the pullway easy breakage in mining process,and the supporting arguments and the construction requirements are determined.The composite supporting technology plays an important role in safe production and improving economic benefit for mine enterprise. |
