Abstract

The embodiment of the invention discloses a blasting method for improving the efficiency of shoveling in open-pit mines, relates to the technical field of mining, and is invented for improving the efficiency of shoveling. The blasting method for improving the efficiency of shoveling in open-pit mines includes: setting the blasting delay time of the hole network in the blasting area; generating isochrones according to the blasting delay time of the hole network; adjusting the blasting delay time so that The ratio of the absolute value of the delay difference between the two adjacent isochrones to the actual distance between the two adjacent isochrones is 10-30 ms / m; blasting is carried out according to the settings. The invention is suitable for explosive mining of open-pit mines.

Description

technical field [0001] The invention relates to the field of open-pit mining, in particular to a blasting method for improving shovel loading efficiency in open-pit mines. Background technique [0002] The cost of open-air bench blasting mining includes four core parts: perforation, blasting, shoveling, and transportation. The costs are mutually restricted. The level of shoveling efficiency is directly linked to the transportation efficiency, which is particularly significant for reducing fuel consumption, power consumption, and improving productivity. [0003] However, in the prior art, there is no systematic and feasible blasting technique to improve the efficiency of shoveling. Contents of the invention [0004] The invention provides a blasting method for improving the efficiency of shoveling in an open-pit mine, which can improve the efficiency of shoveling. [0005] In order to achieve the above object, the embodiment of the present invention improves the blasting m...
