Abstract:

Based on the penetrate into study and practice, the paper systematically analyzed and summarized the application on the cemented stowing of digging groove and cemented stowing of separate wall in the horizontal sub-level mining. According to compare proof by sufficiency,operating efficiency, intention of labor of cemented stowing ,we draw the conclusion that cement stowing of separate wall have a series of advantage, such as facility, high efficiency, good quality,decrease every sub-level mining period and poverty rate etc. There by it is verified that cemented stowing of separate wall is efficacious in the mine that mining method is horizontal sub-level mining.

Key words: separate wall of template, groove on the side, cemented stowing, horizontal sub-level
