摘　　要：科学、合理地选择采矿方法是矿山能否安全开采的关键,采矿方法的选择需要系统地掌握采矿技术条件,并根据矿山开采规模、矿石价值及矿体赋存条件进行具体分析与研究。以某金属矿山为研究背景,采用综合比较法,初选了3种采矿方法,并提出了采场布置参数、回采工艺及充填体强度要求。通过技术和经济比较,最终选取了最优采矿方法,保障了矿山的采矿安全,提高了矿山回采效率,降低了采矿成本。Scientific and reasonable selection of mining methods is the key to safe mining.The selec⁃tion of mining methods requires a systematic grasp of mining technical conditions,and specific analysis and research according to the mining scale,ore value and ore body occurrence conditions.Taking a metal mine as the research background,three mining methods are selected by comprehensive comparison method,and the requirements of stope layout parameters,mining technology and backfill strength are proposed.Through the comparison of technology and economy,the mining method is finally selected,which guarantees the mining safety,improves the optimal mining efficiency and reduces the mining cost.

关 键 词：分段空场嗣后充填法 上向水平分层充填法 预控顶 充填体强度
