采动作业下地表移动变形分析

Analysis about ground surface movement and deformation based on mining operation

为研究采动作业下地表移动变形分布规律,解决因地表移动变形引起的建筑物损害问题,以概率积分法为基础,计算地表移动变形岩移参数.在观测区地表设计并布置岩移观测站,利用取得的地表观测数据,计算出地表水平移动变形值和曲率值,绘制相应曲线对其分布特点进行分析研究.通过计算得出的地表水平移动值和最大正、负曲率值来判定地表建筑物损害程度,分析主断面上的移动变形,确定了移动盆地主断面位置.

To study the distribution regularity of earth surface movement deformation under mining operation and solve the problem of damages to buildings caused by earth surface movement deformation, this paper computed the rock movement parameters of earth surface movement deformation based on the probability integration method, and designed and arranged the observation stations of rock movement in the observation area. The observation data were used to compute the earth surface movement deformation value and curvature, and drew the relevant curve to analyze and research the distribution characters. The movement value and the maximum positive and negative curvature of earth surface were used to determine the damage degree of earth surface buildings, analyze the movement deformation in the main section, and determine the position of movement basin main section. This study provides theoretical basis and method of earth surface movement deformation anticipation.
