Feasibility Analysis of Mining Projects for Protected Pillars of Baijiahuangdi Village

摘要：

　　Using probability integral method,ground movements and deformation of Baijiahuangdi protective coal pillar filling mining are predicated.Based on the analysis of the results of paste-like backfill of the mined working face,the relative mining height of paste-like backfill mining working face along strike is calculated.The results show that movement and deformation are in the range of level I,the building can be used normally under the conditions of unmaintenance and simple-maintenance.Filling mining projects for protected pillars of Baijiahuangdi village is feasible.This achievement has consulting value and theoretic significance to resource reclaiming issues for protected pillars of building.
