摘　　要：根据多金属矿的资源特征和开采技术条件,提出了3种采矿方案,即分段凿岩阶段空场嗣后尾废充填采矿法、并中段分段凿岩阶段空场嗣后尾废充填采矿法和矿柱护壁充填和矿房分段凿岩阶段空场嗣后尾废充填联合采矿法。对3种方案进行了设计,阐述了它们的特点、结构参数和优缺点。最后,通过综合比较分析,推荐选用分段凿岩阶段空场嗣后尾废充填采矿法作为深部低品位厚大多金属矿体开采的实施方案。According to the characteristics of polymetallic ore and its mining conditions, the paper has put forward three kinds of mining programs, namely sub-field subsequent drilling phase space filling mining railings, and the middle sub-field subsequent drilling phase space filling of mining tailings law and wall pillar sublevel stope filling and an empty field subsequent stages of filling the joint mining tailings. In view of these three kinds of program designs, their characteristics, advantages and disadvantages of structural parameters have been described separately. Finally,by comprehensive comparative analysis,it recommends using the sublevel stage subsequent railings fill stope mining method for deep mining of low grade thickness polymetallic ore body as the implementation plan.
