摘要
针对大采高工作面覆岩“三带”高度分布研究,以云顶煤矿13050工作面地质条件为基础,采用数值模拟与现场实测相结合的研究方法,对工作面覆岩移动规律及“三带”高度分布特征进行了研究,对比2种方法的分析结果,发现数值模拟结果与实测得到的覆岩“三带”高度分布特征基本一致,表明数值模拟结果对工作面的安全开采具有一定指导意义。
Be aimed at study on the height distribution of"three zones"of overburden rock in large mining height working face,based on the geological conditions of 13050 working face in Yunding coal mine,the research method of numerical simulation and field measurement is used to study the law of overburden rock movement and the height distribution characteristics of"three zones"in working face.By comparing the analysis results of the two methods,it is found that the numerical simulation results are basically consistent with the measured height distribution characteristics of"three zones"in overlying strata,which indicates that the numerical simulation results have certain guiding significance for the safe mining of working face.
