| Abstract： | According to the environmental state of coal mining subsidence area in Ningguo, this paper proposed the technology scheme of taking abandoned gangue to backfill subsidence area. The feasibility of backfilling foundation with gangue was analyzed using laboratory experiments, and the dynamic compaction method was taken to reinforce gangue for construction of foundation projects. Furthermore, the parameters of the dynamic compaction construction were optimized, and the stability and possibility of building industrial workshop in the backfill area were analyzed by ANSYA software. Engineering practice results showed that it had a significant effect of industry workshop construction using consolidation coal gangue for backfilling subsidence area. This scheme is easy and economic to implement, so it has extensive application value in environment comprehensive management of coal mining subsidence area. |
