为监测地下煤炭开采对某矿工业广场主井井筒造成的影响,建立了井筒地面监测系统,布设了由52个监测点和2个基准点组成的变形监测网。本文在介绍井筒监测网的布设方案、观测方法和各期观测成果质量评价结果的基础上,通过移动变形分析,以主井附近地表监测点的移动变形量为例,采用3DMS系统绘制井筒附近地表监测点移动变形过程图,结合地质采矿条件和监测时间,分析了主井附近地表受开采影响的移动变形规律。
In order to monitor the influence of underground coal mining on the main shaft of a mine industrial plaza, a wellbore ground monitoring system was established and a deformation monitoring network consisting of 52 monitoring points and 2 reference points was laid. Based on the introduction of the layout plan and observation method of wellbore monitoring network and the quality evaluation results of various observation results in this paper, by means of moving deformation analysis, taking the displacement of the monitoring points near the main shaft as an example, the 3DMS system is used to draw the surface near the wellbore With the process of geological deformation and monitoring time, the movement and deformation of the surface near the main shaft affected by mining are analyzed.
