摘要:
以红海矿区11031工作面为研究区域, 通过对其设置地表移动变形观测站, 实地观测得到数据资料, 然后对数据资料进行分析处理, 求得了各种角量参数 (边界角、移动角、裂缝角)、动态参数 (起动距、超前影响角、超前影响距等)、预计参数 (下沉系数q、主要影响角正切tanβ、拐点移动距S、开采影响传播角θ) .结合岩移参数, 采用概率积分法进行了地表沉陷预计, 得到了动态预计参数和下沉盆地预计的可视化模型.在此基础上, 分析出其主要造成了塌陷地和地表裂缝等土地破坏现象.为采空区下降区地表恢复提供指导.%Taking Hami Honghai 11031 working face as the study area, through the set surface movement deformation observation, field observations data information, analyzed the data processing, obtained various angular parameters ( boundary angle, mobile angle, crack angle) , the dynamic parameters ( starting from, impact Angle, advancing distance, etc.) in advance, estimated parameters ( subsidence coefficient q, main influencing tangent tan beta, inflection point move from S, mining influence spread angle theta). Based on the rock shift parameters, the probability integral method is used to predict the surface subsidence, and the visualization model is obtained. On the basis of this, it is analyzed that it mainly caused land damage such as subsidence and surface crack. To provide guidance for the surface recovery of mined-out area.
