摘　　要：针对某露天转地下矿采空区复杂的工程地质条件,利用正交试验对采空区以及露天采坑充填方案进行设计,通过对各充填方案稳定性分析以及经济比较,给出了采空区以及露天采坑最终充填方案,探明了充填方案对三期开采的影响,对复杂工程地质条件下的采空区胶结充填具有指导性的作用。In view of the complex engineering ＆ geological condition of a goaf during transition from open pit to under- ground mining,the orthogonal experiment is used for the design of the goaf and open pit＇s backfilling scheme. Based on the stability analysis and economic comparisons of each backfilling scheme, the final backfilling scheme of goaf and open pit is given, and the impact of the backfilling on the third period project is pointed out. The research plays a guiding significance for the cementing filling of goaf under complex engineering geological conditions.
