The invention provides an uncoupled charge structure, method, application and blasting method. The uncoupled charge method includes a charge preparation stage: preparing an explosive charge roll and a placement device; an uncoupled charge stage: passing through a spacer The parameter and the interval scale parameter define the position and length of the interval in the charge structure; among them, for the interval Rhodes parameter: when the step blasts the interval charge, the interval Rhodes parameter is used to determine the resistance line and / or hole depth and interval The center position is defined; when the tunnel blasts the interval charge, the interval Rhodes parameter is used to define the hole depth and the interval center position; for the interval scale parameter: it is used to define the interval rate and / or interval length. By proposing the interval Rhode parameter and interval scale parameter, the invention accurately describes the interval position and length of the interval charge structure for step blasting in the open-pit mine, and guides blasting design and construction.
Description
technical field [0001] The invention relates to the technical field of rock blasting, in particular to an uncoupled charge structure, method, application and blasting method. Background technique [0002] In the 1840s, Melnikov and Marchenkov of the Soviet Union first proposed a new special blasting technology-air-spaced charge blasting technology. Excessive crushing of the rock mass in the area, thereby improving the utilization rate of explosive energy. A large number of researches and engineering practices show that the use of air-spaced charging technology can obtain more uniform blasting blocks, which can reduce the consumption per unit volume. % of the excavation cost, and at the same time, it can save 10% to 30% of the shipping cost of blasting and crushing slag. [0003] Through indoor and outdoor experiments and a large number of engineering practices by Melniokov et al., it was found that when the air layer is taken as 11-35% of the blast hole volume, the blastin...
