端部夹制下爆堆控制硐室大爆破

Muckpile Controlled Chamber Blasting

本文通过工程实践，探讨存在端部夹制效应和近防护对象复杂条件下，通过合理布药，克服条形药包端部效应，达到控制爆堆边界，松动控制爆破的设计原理及施工经验。

This article investigates the end effects of extended chamber charge throughresonable charge arrangement under the complicated surroundings, the design princpleand implementation expernence for controlling muchpile boundery are introduced.
