Abstract

Combine the actual situation of stope collapse area 56-7# of Dongguashan Copper Mine in china, three-dimensional dynamic monitoring the collapse area twice using Cavity Monitoring System (CMS), taking collapse area measured data as foundation, collapse area three-dimensional model created using Surpac and gain three-dimensional configuration and the actual boundary of the collapse area accurately. Then the bottom structure of stope, the designed stope and ore heap models are established according to the stope design data. Finally, the actual boundary, volume, roof exposure area, collapse range and ore remains of the collapse area are calculated accurately through Boolean operation among the models, a new visible calculation method of integrated information visible calculation for large-scale collapse area is realized effectively. The results show that the longer of the collapse area stay is, the greater of the scope, volume and roof exposure area is. So, it is essential to suspend the blasting around the collapse area and continue to reclaim ore remains. Then backfilling the collapse area and Make plans for reclaim ore body remains.
基于CMS-Surpac的塌陷区三维动态监测
结合冬瓜山铜矿56-7#采场塌陷区的实际情况,利用空腔监测系统(CMS)对塌陷区进行了两次三维动态监测,以塌陷区实测数据为基础,利用Surpac建立了塌陷区三维模型,准确地获得了塌陷区的三维形态和实际边界。然后根据采场设计数据建立采场底部结构、设计采场和矿堆模型。最后,通过模型间的布尔运算,精确计算出了塌陷区的实际边界、体积、顶板暴露面积、塌陷区范围和矿石残余量,有效地实现了一种新的大规模塌陷区综合信息可视化计算方法。结果表明:塌陷区停留时间越长,塌陷区范围、体积和顶板暴露面积越大;因此,在塌落区周围暂停爆破,继续进行残矿回收是必要的。然后对塌陷区进行回填,制定矿体残余物回收方案。
