Taking chance of engineering bid, we provide this blasting program, in which a detailed blasting pull-down technique design and a detailed operation design concerning with the integrated workshop in Kunming Nationalities Brass ware Factory are offered. The critical points are to choose a different-direction collapse blasting program for frame-structure building, to choose all the blasting parameters, to carry out safety management and to adopt safety defense measures as well. According to theoretical analysis and engineering comparison. These designs are correct, feasible and effective. |
