采煤沉陷和高填方沉降双重影响下的地表移动变形预计方法与应用

Surface Movement Deformation Predicting Method and Application under Double Influence of Mining Subsidence and High Fill Settling

为预计采煤沉陷和高填方沉降双重影响下的地表移动变形,以阳泉市采煤沉陷区"光伏领跑者"计划技术基地某光伏地块为研究对象,在分析煤层埋藏特征、开采方法和地表煤矸石堆积、沉降变形特点的基础上,研究了老采空区地表残余变形和煤矸石高填方沉降变形预计方法,提出了2种变形联合预计的技术思路,预计结果为采煤沉陷区光伏建设提供可靠依据。

In order to predict surface movement deformation under double influence of mining subsidence and high fill setting,it taking one photovoltic plot of‘photovoltic pacemaker’plan technical base within mining subsidence of Yangquan city as studying object,and then coal seam buried characteristics,mining method and surface gangue stacking and subsidence deformation variation were analyzed,the predicting method of surface residual deformation of old goaf and gangue high fills setting were analyzed,and two kinds of deformation combined predicting method were put forward,it references for photovoltic constructed in mining subsidence.
