摘要
在缓坡和薄岩层条件下 ,利用单层、多排、集中药包的硐室控制爆破 ,为修筑堤坝提供了合格的块石 ,确保了防洪工程的按时完成。本文论述了硐室爆破的装药计算、爆破参数选择、药室布置、装药和堵塞。
Under conditions of gentle slope and thin rock layer, the controlled chamber blasting with single tier, multi row and concentrated charges was used to provide qualified rock blocks for construction of a dike dam, thus ensuring in time completion of flood control works. In this paper, the charge calculation, the selection of blasting parameters, charged chamber arrangement, charging and stemming, initiation network, and others on the chamber blasting were discussed.
