摘    要:运用空区激光探测系统(CMS)和大型矿床三维软件Surpac等数字化工具,结合冬瓜山铜矿深井采场垮塌区实际,研究一种新颖的大规模采场垮塌区综合信息可视化计算方法。采用CMS对采场垮塌区进行三维探测,获取垮塌区相关信息,并以垮塌区实测数据为基础,运用Surpac构建起垮塌区三维可视化模型,准确获取采场垮塌区三维形态和实际边界;运用采场设计资料建立采场底部结构、回采设计单元及矿堆三维模型,通过模型间的布尔运算,准确计算垮塌区体积、顶板暴露面积及存留矿量等综合信息。研究结果表明:采用该方法可有效地实现大规模采场垮塌区综合信息的可视化计算;计算获得的采场垮塌区信息可靠,为矿山准确掌握垮塌区现状,制定治理及回收垮塌区周围矿体方案提供重要的依据。

Abstract: With the help of the cavity monitoring system (CMS) and mining 3D software Surpac, combining the actual situation of stope of Dongguashan Copper Mine, a new visible calculation method of integrated information for large-scale collapse area was developed. Firstly, the collapse area was monitored using CMS, taking collapse area measured data as foundation, collapse area three-dimensional model of the stope was created using Surpac and the collapse area three-dimensional configuration and the actual boundary were obtained accurately. Then, the bottom structure of stope, the designed stope and ore heap models were established according to the stope design material. Finally, through Boolean calculation of the models, the actual boundary, volume, roof exposure area, collapse range and ore remains of the collapse area were calculated accurately. The results show that the visible calculation of integrated information in the large-scale stope collapse area can be realized effectively. The integrated information of the stope collapse area obtained by this method is reliable, which can be used to hold the actuality of collapse area accurately and offer the important basic basis to manage and reclaim ore body around the collapse.
