云南某铜矿385中段采准系统优化研究

Optimization of Mining Preparatory System of a Copper Mine in Yunnan

采准设计质量的好坏直接决定矿山开采的经济效益和安全水平。通过三维矿业软件反演二维采准设计,并计算其采准设计技术指标,综合分析其合理性,进而提出采准系统优化方案。通过该方案在矿山的成功实施,减少设计采准工程量33058.27 m3,节约工程费用约661万元,取得了良好效果。

The design quality of mining preparation for a mine will have direct effects on its economic benefits and safety of mine production. Taking a Copper mine in Yunnan as the example, the two - dimensional design of mining preparation was inversed by using 3D mining software, the relevant technical indicators of mining preparatory design were calculated,the reasonableness of the technical indicators was analyzed comprehensively, and therefore a optimization scheme of mining preparation system was proposed. Good results were obtained by the successful implementation of the optimized mining preparation system, the mining preparation works was reduced 33058.27 m3 ,the engineering cost was saved 6.61 million yuan.
