Abstract: Self-mobile semi-continuous mining system have a broad application prospect.But it is lacking of theoretical guidance for determining the key technical parameters,such as located level of self-mobile semi-continuous system and moving step of belt conveyor in end slope.The influencing factors that affect the located level of self-mobile semi-continuous system and moving step of belt conveyor in end slope are analyzed,mainly including the throughput of stripping semi-continuous system,transportation cost,occurrence status of coal layer and condition of inner disposing,dynamic relationship between the inner disposing space and the position of the stripping project,and interaction between the located level of self-mobile semi-continuous system and moving step of belt conveyor in end slope.Under the condition of restrictive inner disposing space,with the goal of realizing lowest transportation cost,the method to optimize the located level of stripping self-mobile semi-continuous system and the moving step of belt conveyor in end slope is proposed.

Key words: Self-mobile crusher semi-continuous mining system, Located level, Moving step, Transportation cost, Optimization
