Abstract
The environment treatment of Tangzishan,Huzhou city,Zhejiang Province,involved three mountains.Based on the complicated surroundings in the area,the requirements of construction and schedule,deep-hole bench blasting combining short-hole blasting was proposed for this project.In this paper some usual technological problems and difficulties occurring in blasting design and construction under complicated circumstances along with the solving solution and optimized blasting parameters were discussed.The construction went smoothly,speedy and safely,and therefore,the blasting achieved its goal.Good social effects and economical returns were obtained.
