| 摘 要： | 针对建筑物保护煤柱的煤炭资源回收问题,根据西马煤矿具体地质采矿条件,选择概率积分法对西马峰村保护煤柱开采后引起地表移动变形进行预计;并以1326工作面似膏体充填开采结果为基础,计算出充填采区工作面的等效采高;预计结果表明,如按设计开采方案布置工作面,西马峰村建筑物损害等级为Ⅱ级,不符合预先制定的标准;将开采方案进行一定的调整后再进行预计,结果表明,西马峰村建筑物所处地表的移动变形值均在建筑物损坏等级I级所规定的范围内,即建筑物在不用维修或简单维修的情况下可以正常使用,则西马峰村保护煤柱似膏体充填开采是可行的。

| Abstract: | Aming at the problem of reclaiming coal resources of protective coal building pillar, According to the geological conditions, Using probability integral method, it is predicted that ground movements and deformation of Ximafeng protective coal pillar filling mining. Based on the analysis of the results of paste-like backfill of the mined 1326 working face, it is calculated that the relative ＂mining height＂ . The results show the movement and deformation are in the range of level- Ⅱ if minging as the original plan and do not meet the advanced standard. After adjusting the scheme, The results show that movement and deformation are in the range of level- Ⅰ, the building can be used normally in the conditions of un-maintenance and simple-maintenance. Filling mining projects for protected pillars of Ximafeng village is feasible. |
