Application of design of blasting construction net about cascade near to town or village

Blasting construction is always payed attention to by the engineers,especially the blasting spot near to the building.The contradiction among the construction safety,the construction quality and construction efficiency is solved by blasting construction,and the environment protection should be absorbed in.Based on the disadvantage factors in the blasting construction beside the towns,the theories of blasting construction,the design technology of blasting net,the construction process and operation method are discussed.The noticed problem in blasting construction is pointed out,and the technology parameters of the blasting construction are analyzed,combined with the beach example of Chishui River.The result achieve the aim of emergency control and quality control,resource saving and cost saving.
