摘　　要：为实现蒙库铁矿井下天井掘进机械化,提升矿井下作业的本质化安全水平,蒙库铁矿应用了无切井拉槽技术。组织中深孔凿岩台车实施钻孔,运用延期爆破以楔形掏槽[1]的方式完成切割拉槽工序,并推广应用于其它分层。The non-cutting raise technology have been applied to the Mengku iron mine to improve the driving mecha-nization of underground and enhance the essential safety level of the mine operation.The drilling is carried out with medi-um and deep hole drilling platform, and the cutting and pulling process is completed by the wedge-shaped cutting way bythe delay blasting, and it is popularized and applied to other layers.

关 键 词：无切割天井 楔形炮孔 补偿空间 延期爆破 拉槽
