摘　　要：为了研究义煤集团云顶煤矿12040工作面上方地表因工作面的采动对地表造成的影响,在地表布置测站使用了RTK每隔一定时间进行实地测量,同时还结合监测数据进行了拟合,又使用了FLAC^(3D)对云顶煤矿的地质参数进行数值模拟,对12040工作面对地表造成的沉降进行了分析。结合多种方法最终得出,云顶煤矿12040工作面实际上为非充分采动,并且云顶煤矿主采的二1煤上覆岩层为中硬岩层;同时利用上覆岩层的属性结合RTK监测的数据得到了云顶煤矿地层的基本参数,结合监测数据进行拟合绘制了理想状态下12040工作面上方地表的三维沉降图与地表沉降等高线;利用FLAC^(3D)模拟了工作面推进不同长度时,12040工作面煤层上部岩层的垂直应力分布、垂直位移分布及工作面上方地表沉降规律。In order to study the impact of mining activities on the surface above the No.12040 working face of Yunding Coal Mine of Yimei Group,RTK was used to monitor the ground surface at regular intervals,and the monitoring data was fitted.RTK was used to conduct field measurements at regular intervals on the surface,and fitting was performed based on monitoring data.FLAC^(3D)was also used to simulate the geological parameters of Yunding Coal Mine for numerical simulation,the settlement caused by coal mining work on the No.12040 working face on the surface was analyzed,after the combination of various methods,the conclusion was finally obtained.The No.12040 working face of Yunding Coal Mine is actually not fully mined,and the overlying strata of theⅡ1 coal seam in Yunding Coal Mine are medium hard rock.At the same time,the basic parameters of the strata in Yunding Coal Mine were obtained by using the attributes of the overlying strata combined with the RTK monitoring data,and the three-dimensional subsidence map and the surface subsidence contour of the surface above the No.12040 working face under the ideal state were further fitted and drawn in combination with the monitoring data.FLAC^(3D)was used to simulate the vertical stress distribution,vertical displacement distribution and surface subsidence law of the upper strata of the No.12040 working face when the working face was advanced by different lengths.
