井筒地表监测网建立及移动变形规律分析

Establishment of the shaft ground monitoring network and deformation analysis

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。

To monitor the impact on the main shaft of a mine industrial square caused by underground coal mining, a shaft ground monitoring system, composed of 52 monitoring points and 2 datum points, constituted the deformation monitoring network, is established. This paper introduces the design of the shaft monitoring network, methods of observations, and observation results of each epoch. Take the amount of movement and deformation of the surface monitoring points in the vicinity of the main shaft as an example, 3DMS system is used to draw movement and deformation figures near the shaft. Combined with the geological and mining conditions, movement and deformation of the main shaft caused by the mining is analyzed.
