龙滩矿井采煤工作面诱发开采沉陷的动态变化特征
|
摘要
为掌握地下开采引起的地表沉降动态变化规律与特征,在龙滩矿井3115工作面对应地表建立地表移动观测站,运用理论分析法对监测数据进行分析整理,据此绘制地表移动变形曲线并详细叙述其特征。研究结果表明:地表最大下沉值约为73 mm;各测点的下沉值、倾斜值及曲率值随工作面推进呈逐渐增大的变化规律。通过掌握工作面开采时地表移动变形规律,可为开采沉陷综合治理及矿区地质环境保护工作提供数据支持和技术性指导。
In order to master the dynamic variation rules and characteristics of surface subsidence caused by underground mining,a surface movement observatory was established on the surface of 3115 working face in Longtan Mine. Based on the analysis of the monitoring data by theoretical analysis method,the surface movement deformation curve was drawn and its characteristics were described in detail. The results show that the maximum subsidence is around 73 mm; the subsidence value,inclination value and curvature value of each measuring point increase gradually with the advance of the working face. By mastering the law of surface movement and deformation in mining of the working face,it can provide data support and technical guidance for comprehensive control of mining subsidence and geological environment protection of mining area.
