Analysis of Stability of Sloping Base Inner Dump during Transition Alternative of Mining Area in AJL Surface Coal Mine
This paper is based on the Luzigou anticline geological structure encountered in the process of inside dump which caused a big range of falling of basement and had a serious effect on row abandon plans in Anjialing surface mine.The authors analyzed the internal force,displacement,the plastic zone and other relevant circumstances,calculated correlative coefficient of stability,made a comprehensive evaluation of dumping process.Based on this,the paper came up with a project implementation of transition alternative mode plan from Z shaped work line to L shaped work line engineering and technical solution which could improve the security situation in the dump,make sure the inner dump slope stability.Selected the ways of dump plan dumping arrangement.
