摘　　要：甲玛铜多金属矿地下二期主采区域为近水平极厚大矿体,破碎氧化带在该区域内普遍分布,且主要呈现出矿石氧化率高、节理裂隙发育、水文地质简单等典型特征,顶板垮冒、侧帮垮落等现象导致现有分段上向中深孔空场嗣后充填采矿法存在较大安全隐患。为此,提出采用下向大直径中深孔与上向扇形孔联合空场嗣后充填采矿法回采破碎氧化带区域矿体,该采矿方法有利于保护采场顶板,防止出现顶板垮冒,下向平行孔的布置有助于更好的控制采场边界,减少因矿岩破碎而造成的侧帮垮落,改善了破碎氧化带区域采场生产作业环境,具有极佳的推广应用价值。The main mining area in the phase II of Jiama Copper Polymetallic Mine is a near horizontal and extremely thick large ore body,and the broken oxidation zone is widely distributed in this area,which mainly presents typical characteristics such as high ore oxidation rate,joint fissure development,simple hydrogeology,etc.The phenomena of roof collapse,side slope collapse and so on leads to great safety hazards in the existing sublevel upward medium deep hole open-stope method with subsequent filling.Therefore,the open-stope method with subsequent filling combining downward large-diameter medium deep hole and upward fan-shaped hole was put forward.This mining method is conducive to protecting the stope roof and preventing roof collapse.The arrangement of downward parallel holes helps to better control the stope boundary,reduces the side slope collapse caused by broken ore rock,improves the stope production and operation environment in the broken oxidation zone,and has an excellent popularization and application value.
