【摘要】 姑山铁矿选用上向水平分层充填采矿法和上向进路充填采矿法在不同的地质条件下开采，为对采场结构进行优化，本研究通过理论分析和工程类比的方法提出3～4种采场参数方案，再根据数值模拟手段，从采场安全性、生产效率和生产安排等方面选出合适的采场方案，优化布置，为矿山安全高效开采、降低损失贫化提供设计参考。更多还原

【Abstract】 Gushan iron ore mine selects upward horizontal stratified filling mining method and upward approach filling mining method to mine under different geological conditions, in order to optimize the structure of the quarry, this study proposes 3-4 kinds of quarry parameter schemes by means of theoretical analysis and engineering analogies, and then according to numerical simulation means, selects the suitable quarry scheme from the aspects of quarry safety, productivity and production arrangement, optimizes the layout, and provides design references for mine provide design reference for safe and efficient mining and reduce loss depletion.更多还原
