一种新颖的采场存留矿量可视化计算方法

存留矿量因直接关系到矿床资源的回收程度而被视为是衡量采场回采质量的一个重要指标。针对我国目前对采场存留矿量缺乏有效计算方法这一现实，综合运用空区三维精密探测系统CMS(Cavity Monitoring System)和SURPAC等数字化手段，研究形成了一种新颖的基于采空区三维精密探测的采场存留矿量可视化计算方法，即先采用CMS空区探测系统对采空区进行三维精密探测；然后以空区实测数据和采场回采设计资料为依据，运用SURPAC软件分别构建采空区、采场回采设计单元和采场底部结构的三维模型；以此为基础，建立采场底部存留矿石的三维实体模型，准确地获取存留矿石在采场底部的空间分布及体积大小，进而计算出存留在采空区中的矿量。实际应用表明，该方法实用可靠，从而为矿山准确计算存留矿量提供了一种有效的技术手段。

A New Visualization Calculation Method for Residual Ore

The residual ore amount is regarded as an important index for assessing the extraction quality of a stope as it is directly related to the recovery level of mineral resource. In view of the lack of an efficient calculation method for the residual ore in stope, digitalization means such as CMS (Cavity Monitoring System) and SURPAC were comprehensively used in the study. As a result, a new visualization calculation method for stope residual ore was developed, which is based on 3D precision detection of cavities. First, CMS is used to make a 3D precision detection of a cavity; and then SURPAC, to construct the 3D models for the cavity, designed mining unit and bottom structure of the stope. On this basis, a 3D entity model for the residual ore at the stope bottom is constructed. From the model, the spatial distribution and the volume of the residual ore at the bottom can be accurately obtained and the ore amount in the mined cavity can be calculated. The practical application has proven that the method is practicable and reliable and provides an efficient technical means for an accurate calculation of residual ore amount.
