摘要
随着浅地层矿产资源开发逐渐枯竭,深井矿床开采势必成为我国战略资源开发的主要阵地.但深井开采所面临的"三高一扰动"将制约深井矿床开采的安全性,大幅增加了规模化开采的难度,合理采矿方法的选择是解决深井矿床高效安全开采的前提.引入 Critic赋权法,构建了深井卸荷采矿方案综合优选评价模型.以国内某深部特大型矿床为工程背景,提出4种卸荷开采方案,并用建立了的Critic客观赋权法综合评价模型进行评价.结果表明,方案四(即盘区分层卸荷大断面进路开采方案)为最优方案.基于优选方案开展了现场工业试验,试验结果显示,推荐的开采方案具有卸荷效率高、生产能力大、贫损指标低等优点,验证了将Critic赋权法引入深井卸荷采矿方案优选的可行性和适用性,为国内矿山提供了一种深井卸荷采矿方案优选思路.
Abstract
With the gradual depletion of shallow mineral resources,deep mine mining is bound to become the main battlefield for strategic resource development in China.However,the high ground stress,high ground temperature,high permeability,and strong mining disturbance faced by deep mine mining will restrict the safety of deep mine deposit mining,greatly increasing the difficulty of large-scale mining.The selection of reasonable mining methods is a prerequisite for solving the efficient and safe mining of deep mine deposits.A comprehensive optimization evaluation model for deep unloading mining schemes was constructed by introducing the Critic weighting method.Four unloading mining schemes were proposed by taking a deep super large mineral deposit in China as the research background,and a comprehensive evaluation model based on Critic objective weighting method was established to evaluate the proposed schemes.The results indicate that the fourth scheme,namely the panel layer unloading and large cross-section approach mining method,is the optimal solution.Based on the optimized scheme,field industrial tests were conducted,and the test results proved that the recommended mining scheme has the advantages of high unloading efficiency,high production capacity,and low dilution loss indexes.The feasibility and applicability of introducing Critic weighting method into deep mine unloading mining scheme selection were verified,providing a new idea for optimal selection of deep mine unloading mining scheme in domestic mines.
