1、 摘 要 山区开采沉陷是开采沉陷研究中的重点部分,尤其对于山西这个多山且煤炭资源丰富的地区,其研究意义重大。 由于受到山区地形地貌 因素 的影响 及岩体本身的复杂性 ,山区开采沉陷地表移动规律与平原地区有很大的区别。 本文结合 五矿 83201 工作面 地表移动观测站监测数据,处理数据得到下沉、倾斜、曲率、水平移动及水平变形值,并求取 83201 工作面 的地表移动参数,包括角量参数、动态参数和概率积分法预计参数。 根据数据处理结果分析总结了山区开采沉陷地表移动规律特征,山区地表移动变形系地质采矿条件和地形因素综合影响的结果。本文研究内容对山区开采沉陷预计、保护煤柱留设、煤矿安全生产及地面建(
2、构)筑物保护有一定的理论指导意义。 掌握地表实际移动变形参数,观测地面建筑物的破坏状态,以合理地调整矿井采掘布署,提高煤炭资源的回收率。 关键词 : 开采沉陷; 观测站 ; 监测数据 ;地表移动 ABSTRACT The research of mining subsidence in mountain area is the focus part of the subsidence research. For the mountainous and rich coal resources region-Shanxi, it has especially significant meaning
3、 in this part. Due to the influence factors as topography and the complexity of the rock mass underground mining, land sinking law in a mountainous area is different from that on flat ground. The paper selects wu Coal Mine 83201 working face as the research region, monitoring data from observation s
4、tations is arranged. Processed data to obtain subsidence values, inclination values, curvature values, horizontal movement values, horizontal deformation values. The paper analysised the law of surface movement and deformation of mining subsidence in mountain area, The quality of ground subsidence i
5、n mountain areas is not only caused by underground mining factors but also by terrain and landforms. The valuable study of this paper can give a guiding significance to mountain mining subsidence prediction, protection pillar reserve, Coal mine production safety and protection of buildings. To grasp
6、 the actual ground movement and deformation parameters, observing the destruction of the ground state of the building, in order to reasonably adjust mine mining deployment and improve the recovery rate of coal resources.
