采用阶段空场嗣后充填法的矿山,矿房的回采指标不仅关系到采场回采质量,与采空区的后续充填、矿柱的回采等采矿活动也都密切相关。采用CMS对采空区实施精密探测,运用Surpac等数字化手段,结合某铜矿采场实际,分析了采场环境因素与测点的选择对CMS探测的影响,提出了采场周边超挖量、存留矿石量及回采贫化等回采指标的可视化计算方法。实践证明,计算获得的采场回采指标可靠,可用于矿山回采质量评价及矿山生产管理。
The mining and mining mines’ recovery indicators using the post-filling method in the stope are not only related to the quality of the stope mining, but also closely related to the mining activities such as follow-up filling of mined-out area and pillar recovery. Using CMS to carry out precise exploration in goaf, using Surpac and other digital means, combined with the actual copper stope, the influence of stope environmental factors and measuring points on CMS detection was analyzed, The amount of remaining ore and recovery of mining and other indicators of mining visual calculation method. Practice has proved that the calculation of stope mining recovery indicators reliable, can be used for mining quality evaluation and mine production management.
