某实测采空区的稳定性综合分析

Comprehensive Analysis of the Stability of an Actual-measured Mined-out Area

为了获得更可靠的采空区稳定性分析数据,采用三维激光探测仪对某采空区进行探测,准确地获取了空区的三维形态及分布状况,并结合三维矿业软件Surpac建立了空区的实际模型。在此基础上,通过耦合技术用FLAC3D对其进行力学模型的数值分析,最后结合现场布设的光弹应力计监测结果与数值模拟进行比对,两者结合起来对该空区稳定性进行综合的分析与评价,为矿山后续安全生产和管理提供科学的理论依据。

In order to obtain more reliable data on stability analysis of goaf,the 3d laser detector is adopted to detect the mined-out area to accurately acquire its 3D shape and distribution. Combining with the actual model with 3D mining software Surpac for mined-out area,the numerical analysis on the mechanics model is made with FLAC3D through the cou- pling technology. Finally, the monitoring results with the on-site photoelastic stress meter and the numerical simulation re- suhs are contrasted, and a comprehensive analysis and evaluation on stability of the mined-out area is made. This research can provide a theoretical basis for the subsequent safety production and management.
