应用空区探测系统(Cavity Monitoring System,简称CMS),精确地获取地下矿山采空区的三维形态和准确的空间位置,并借助大型三维矿床软件SURPAC建立起了空区的三维形态模型,在此基础上,研究提出了空区稳定性数值模拟建模的SURPAC和FLAC如耦合方式,形成了基于实测的采空区稳定性数值模拟分析的新方法,有效地提高了采空区稳定性数值模拟结果的准确性和可靠性。该方法已在铜坑矿采空区群稳定性数值模拟研究中成功应用,验证了该技术的有效性和可靠性。
Three-dimensional shape and space location of underground mined-out area were got by using Cavity Monitoring System and three-dimensional model of the mined-out area was made by using three-dimensional ore body software SURPAC. Coupling mode between SURPA and FLAC^3D was studied and new method of numerical simulation analysis was formed on front said method, in result, improving accuracy and reliability of numerical simulation for mined-out area group stability. The method been applied in numerical simulation study for mined-out area group stability in Tongkeng Mine.
