Analysis of filling effect and filling ratio of backfill mining in longwall face
长壁工作面充填开采的充填比与充填效应分析
Based on full literature search and comprehensive analysis,the current status is described from the mining technologies of coordinated mining,backfill mining,partial strip mining,and filling the collapsed cavities in over lying strata.
在综合分析大量文献的基础上,从协调开采法、充填开采方法、条带开采、覆岩离层注浆等多种开采技术对建筑物下开采方法进行了研究和论述;展望了我国建筑物下开采的发展趋势,认为覆岩离层注浆、矸石充填、条带开采、原地重建抗变形房将是我国建筑物下采煤技术的发展方向。
