摘要
采用安全系数法,结合条带煤柱最小宽度、宽高比、采出率等对条带采空区内遗留煤柱稳定性进行分析、评价;在综合分析国内外采空区治理技术、经验的基础上,根据具体的地质采矿条件,提出了采用条带煤柱充填回收治理对策,并结合具体实例进行了可行性论证,结果表明采用条带煤柱充填回收治理条带采空区技术可行、经济效益显著。
Applying safety efficient method and combining minimum width of strip coal-pillar, ratio of width and height, mining ratio, coal-pillar stability in gob was analyzed and evaluated. On the basis of comprehensively analyzing domestic and abroad gob treatment technology and experience, a countermeasure of applying mining strip coal-pillar with stowing was put forward. Feasibility of the method was discussed with actual example. Result showed that taking mining strip coal-pillar with stowing as gob treatment method was techni-cally feasible and its economic profit was prominent.
