煤矿水平开采地表变形监测与分析

Monitoring and analysis of surface deformation in horizontal mining of coal mine

针对煤峪口矿14号煤层因水平开采引起的地表变形,根据工作面地质条件差异引起的地表塌陷,结合传统的动态测量技术和拉绳变形位移实时监测技术,对塌陷区特征点的三维变形位移情况进行监测,数据分析表明,在工作面的西北端,地表变形较稳定,在工作面的东南端,地表的垂直和水平变形严重,通过动态观测和实时观测,可以准确获取地表的变形参数,为后续研究积累经验。

In view of the surface deformation caused by horizontal mining in No.14 coal seam of Meiyukou Coal Mine,according to the surface subsidence caused by the difference of geological conditions of the working face,combined with the traditional dynamic measurement technology and real-time monitoring technology of rope deformation and displacement,the three-dimensional deformation and displacement of the characteristic points in the subsidence area were monitored.The data analysis showed that the surface deformation was stable at the northwest end of the working face,and the vertical and horizontal deformation of the surface was serious at the southeast end of the working face.Through dynamic observation and real-time observation,the deformation parameters of the surface could be accurately obtained,which accumulated experience for subsequent research.
