摘要
随着矿山开采深度的增加,空场采矿法面临着更大的安全隐患与环境压力。充填采矿法作为一种安全和绿色的采矿技术,已广泛应用于矿山开采中。以某大型铜矿为研究对象,结合理论分析和数值模拟方法,对上向分层点柱充填采矿法的采场结构参数进行优化研究,系统分析采场长度、点柱尺寸和点柱中心间距等参数对采场稳定性和矿山生产能力的影响。结果表明,当采场长度为65 m,点柱尺寸为5 m×5 m,点柱中心间距为15 m时,矿山采场的稳定性较高且生产效率最佳。该采场结构参数优化方案不仅能有效保障矿山的安全开采,还能提高资源利用率,为类似矿山的充填开采技术应用提供了科学依据。
With the increase of mining depth,open stope mining method is facing greater safety hazards and environmental pressure.Filling mining method,as a safe and green mining technology,has been widely used in mining.Taking a large copper mine as the research object,combined with theoretical analysis and numerical simulation methods,the stope structure parameters of upward layered point pillar filling mining method were optimized,and the effects of stope length,point pillar size and point pillar center spacing on stope stability and mine production capacity were systematically analyzed.The results show that when the stope length is 65 m,the point pillar size is 5 m X5 m,and the point pillar center spacing is 15 m,the stability of the mine stope is high and the production efficiency is the best.The optimization scheme of stope structure parameters can not only effectively guarantee the safe mining of the mine,but also improve the utilization rate of resources,which provides a scientific basis for the application of filling mining technology in similar mines.
