煤矿延深区岩移观测方案设计与沉降分析

Scheme Design and Settlement Analysis of Rock Movement Observation in Coal Mine Deepening Area

矿井掘进的长度增加,使得矿井延深区的纵深逐渐加长,持续进行岩移观测有利于取得地表的移动、变形及破坏规律,为建筑物、水体、铁路及主要井巷煤柱的开采提供评价依据。针对某矿井延深区岩移沉降观测项目,研究该延深区的总体情况,设计相应的岩移观测方案。通过多点多期岩移观测成果,对该延深区的沉降情况进行综合评价。

For the increase of the length of the mine excavation,the depth of the mine extension area is gradually lengthened.Continuous rock movement observation is conducive to obtain the surface movement,deformation and damage laws,and provides evaluation basis for the mining of buildings,water bodies,railways and main roadway pillars.Aiming at the observation project of rock movement and settlement in a mine extension area,the overall situation of the extension area is studied,and the corresponding rock movement observation scheme is designed.Based on the observation results of multi-point and multi-stage rock movement,the settlement of the extension area is comprehensively evaluated.
