石膏矿采空区稳定性分类的综合评判法研究

为有针对性地治理采空区,有必要对石膏矿山采空区稳定性进行合理地分类,为此提出了采空区稳定性分类的综合评判法.该评判法将采空区的存在时间、采空区的面积、矿柱面积比率、矿柱宽高比、采空区是否有水、当前来压情况及采空区周边情况作为主要分类标志,依据综合得分情况对采空区稳定性进行合理划分.研究成果对石膏矿山采空区稳定性分类提供了重要依据及借鉴,可在石膏矿山生产实践中推广应用.

Comprehensive evaluation of classification of stability for mined-out area in gypsum mine

In order to treat mined-out area,proper classification of stability for mined-out area is necessary,so the comprehensive evaluation on classification of stability for mined-out area is put forward.This method takes existing time,total area,ratio of pillar area,ratio of pillar width to height,water state,present press presentation,surrounding conditions of mined-out area as the main classification signs,and comprehensive marks is calculated to classify stability of the mined-out area.The research result can give great reference and experiences to stability classification of mined-out area,also it can be widely used in production practice in gypsum mine.
