Abstract
With the gradual advancement of the construction of super large mines in China,the requirements for the supply and quality of underground concrete have been constantly improved.Especially in recent years,the development and applica-tion of rapid tunneling technology in northern Shaanxi has significantly improved the footage of roadway tunneling,but also led to the obvious lag of the corresponding roadway floor construction and shotcrete support project.In order to further im-prove the efficiency and quality of concrete transportation,the material conveying hole,underground concrete mixing station and supporting roadway project were innovatively designed,and the equipment of underground mixing station was selected,and the concrete mixing station was installed underground.A new underground concrete conveying and manufacturing process is proposed:sand,gravel and other raw materials are transported to the underground through the ground feeding hole,processed into finished concrete by the underground mixing station,and finally transported to the application site by trackless rubber tyred truck.The project design was successfully applied in Xiaobaodang Coal Mine.关键词
