Abstract:

Based on the penetrate into study, the paper systematically analyzed and summarized the application on the cemented stowing of digging groove and clot of injection 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-levelmining period and poverty rate etc . Thereby it is verified that cemented stowing of separate wall is efficacious in the mine that mining method is horizontal sub-level mining.

Key words: clot of injection, groove on the side, cemented stowing, horizontal sub-level
