摘　　要：攀枝花马家田尾矿库位于攀枝花市仁和区阿署达村,该尾矿库为原亚洲第一尾矿库,施工过程中采用了爆破、灌浆等一系列施工技术。以冉家湾隧道下穿马家田尾矿库为例,介绍了隧道的施工技术内容,包括隧道下穿尾矿影响段、下穿尾矿段、下穿引水洞段采取的控制爆破方案和注浆方案,希望能够为相关人士和同类工程提供参考。The Majiatian tailings pond in Panzhihua City is located in Ashuda Village,Renhe District.The tailings pond was originally the first tailings pond in Asia,and a series of construction techniques such as blasting and grouting were used during the construction process.Taking the example of the Ranjiawan Tunnel passing through the Majiadian Tailings Reservoir,this article introduces the construction technology content,mainly including the controlled blasting and grouting schemes adopted for the tailings impact section,tailings section,and water diversion tunnel section of the tunnel.It is hoped that this can provide reference for relevant personnel and similar projects.
