Description

Technical Field

[0001] The present application relates to an intelligent design method for a blasting scheme, and belongs to the technical field of rock blasting. Background Art

[0002] With the rapid development of domestic infrastructure and the rich experience of infrastructure construction, when excavation construction is carried out under complex geological conditions (such as high slopes), slope blasting is often carried out first, and then excavation equipment is used for excavation. When blasting a high slope, it is necessary to design a blasting plan according to the high slope, and then build blasting points according to the blasting plan to reduce the impact of slope blasting on the surrounding environment, while reducing blasting at unnecessary locations, thereby preventing greater damage to the geological environment of the slope.

[0003] At present, the design of slope blasting schemes is based on the slope address, environment and other data collected by blasting designers, and then combined with personal design experience to design blasting schemes. The design of blasting schemes requires relevant personnel to analyze the detected slope geological data, and use their subjective judgment to determine how many blasting points are needed for the slope geology and the amount of explosives in the blasting points. If the relevant personnel make a mistake in their subjective judgment of the current slope geology, or if the current slope geology changes due to unexpected factors such as micro-earthquakes, then the use of the artificially designed blasting scheme to blast the current slope will cause an accident. When the accident is minor, the slope after blasting will be different from the expected blasting target, affecting the later excavation of the slope and thus prolonging the construction period. When the accident is serious, it will have a serious impact on the geology of the nearby mountains, causing landslides in the mountains and threatening the safety of the construction teams stationed nearby.
