摘要
以采集到的现有数据资料为基础,采用相似材料模拟实验的方法,建立物理模型,研究充填开采时不同充填率对覆岩变形特征,并与垮落法开采相对比,最后与煤矿实测数据进行验证得出充填开采对覆岩变形破坏的影响机理。
Based on some of the data and information,this paper use a number of experiments on similar materials and build physical models to study the effect of different filling ratio on deformation character of overburden strata. And compared with caving method. Finally with the actual measured data validation draw mine backfill mining overburden deformation on impact mechanism.
