APPLICATION OF BLASTING DISTURBANCE SEDIMENT TECHNOLOGY IN THE TEST OF WATER AND SEDIMENT REGULATION IN LOWER REACHES OF YELLOW RIVER

For transporting sediment as much as possible to the ocean and reducing sediment deposition effectively in the lower reaches of Yellow River,sediment should be increased by the means of sediment disturbing during the test of water and sediment regulation.Resulting from the quite mature underwater blasting technology,the blasting in test of water and sediment regulation can release enough energy in set time,which can disturb the sediment with enough intensity and capacity,though the test was subjected to limited time,wide operation space and tremendous amount of sediment needed to be disturbed.This paper discusses the project design and safety in the blasting disturbance sediment together with the demonstration of feasibility of blasting disturbance sediment technology in the test of water and sediment regulation in the lower reaches of Yellow River.
