摘　　要：傲牛矿265中段131线至130线之间的矿体距离小北沟露天坑较近,矿体非常破碎,且属于矿体尖灭带。基于此,研究提出了利用中深孔爆破诱导破碎矿体崩落的采矿方案。首先在采场沿脉内施工3个临时垂直钻孔确定顶板岩石破碎高度及矿岩分界线;其次采用中深孔钻机钻孔精准爆破;最后在采场爆破后利用铲车人工出矿,当破碎矿体经过诱导自然崩落到采空区并且濒临采空区后,改为遥控智能铲车进入采空区出矿。现场实践证明爆破诱导崩落采矿能够提高矿石回采率,对矿体顶底板破坏性小、人员作业安全性高,能够为同类矿体的开采提供借鉴。The orebody of between line 131 and line 130 in 265 middle section of aoniu iron mine is close to Xiaobeigou open pit.The orebody is very broken and belongs to the pinch out zone of orebody.Based on this,the mining technology of using medium deep hole blasting to induce the collapse of broken ore body is put forward.Firstly,three temporary vertical boreholes were constructed along the vein to determine the roof rock breaking height and ore rock boundary;Secondly,medium deep hole drill is used for drilling and blasting;finally,forklift is used for manual ore drawing after stope blasting,When the broken ore body is induced to collapse naturally to the goaf and is close to the goaf,the remote intelligent forklift is used to enter the goaf for ore drawing.The field practice has proved that the Blasting Inducement Caving Method can improve the recovery rate of the mine,has little damage to the roof and floor of the ore body,and has high safety for personnel operation,which can provide experience for the mining of similar ore bodies.
