| Abstract: | 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. |
