摘　　要：准确掌握采空区形态、大小及其边界是控制因采空区引发的灾害及优化采矿设计等的重要基础性工作。运用空区三维激光探测系统对采空区进行精密探测,获取探测数据,对原始数据处理后,运用三维建模软件Surpac精确构建复杂空区三维可视化模型,直观地表达空区的空间形态;以空区三维模型为基础,进行空区的体积、顶板面积和采场周边的超、欠挖量、存留矿量、采场塌陷区回采指标的计算及动态监测,并准确获得了采空区的实际边界等相关信息,从而为矿山进一步开展矿柱爆破设计、空区充填、贫损测定与控制,以及进行采场垮塌区处理等提供可靠的基础性依据。Accurate knowledge of a disastrous cavity＇s shape,size and boundary is an important basic for controlling cavity collapse and optimizing mine design.With the results of precise detection of a complicated cavity by 3D Cavity Monitoring System,3D visual model of the cavity was built by Surpac.On the basis of the 3D model,the thesis calculated the cavity volume,roofs area,volume of over-excavation,under-excavation around the cavity,retention ore mining index.A dynamic monitoring of stope subsidence was conducted and got accurate information of borderline and sections,providing the reliable data for blasting design,filling design,ore dilution control and stope subsidence treatment.
