摘　　要：受大量不明采空区及井下开采作用影响,毛坪铅锌矿出现了大范围采空区坍塌,严重危及地表及矿山的安全生产,通过2年地表注浆加固、封闭充填等塌陷空区综合治理,取得了控制塌陷坑变形的可靠效果,同时科学论证选择下向进路充填采矿法开采深部矿体,生产实践采出矿石7.48万t,矿石损失率为3%,贫化率为6%,新增利润1.02亿元。Due to a great amount of unknown goaf and underground mining,large-scale collapse occurred in Maoping Lead &Zinc Mine,which endangered the production safety seriously.Measures such as grouting reinforcement,closing filling,were taken to comprehensively control the collapsed goaf in two years,and reliable effect was obtained. Moreover,downward drift cutand-filling stoping method was chosen for deep mining through scientific verification. In practice,74800 tons ore were produced with ore loss rate of 3% and dilution rate of 6%,and the profit was increased by 102 million RMB.
