【摘要】 杨林坳矿区矿体为倾斜的梳状矿体,呈不规则的板状体产出,厚度变化不稳定,矿脉之间夹石厚度为2～22 m不等,开采技术难度大。针对杨林坳矿区矿体的赋存特点,在分析国内外类似矿体开采技术的基础上,提出了阶段矿房连续采矿法、阶段强制崩落法、盘区机械化上向分层充填法3种方案,并进行了综合评价,最终推荐盘区机械化上向分层充填采矿法为杨林坳矿区2号矿体63～65线6中段以上矿段的开采方案。更多还原

【Abstract】 The ore-body of yanglin’ao mine area is declining pectination and produced as anomalistic board form,unstable changing thick,the thickness of dunn bass at 2～22m,difficult to mining.According to the occurrence feature of ore-body and analysis of similar ore-body mining technology in and abroad,promoted stage-room continuous stoping,stage-compulsory caving method,panel mechanization upward stratified filling method and complex evaluation,finally commended the panel mechanization upward stratified filling method to mining the 63～65line 6 middle part of No.2 ore-body of yanglin’ao mine area.更多还原
