Embodiment Construction

[0133] Step 1: According to the physical and mechanical properties of the rock and the requirements of blasting engineering, determine the parameters such as the unit consumption of explosives, the diameter of the drilling hole and the charge per hole.

[0134] Step 2: Determine the standard hole network parameters in the isotropic rock state according to parameters such as explosives and single-hole charge.

[0135] Step 3: On-site measurement of the explosion energy propagation velocity v of the rock mass in the explosion area along the direction of the rock formation and perpendicular to the direction of the rock formation 1 and v 2 value, according to this value to find the correction coefficient k 1 and k 2 value.

[0136] Step 4: According to the correction coefficient k 1 and k 2 Correct the standard explosive energy body parameters and standard hole layout parameters of the anisotropic rock mass (actual rock mass), and obtain the standard explosive energy body par...

Abstract

The invention provides a rock blasting method. An optimal rock blasting design scheme is proposed according to an optimal crushing principle of the method, that is, how to maximize the distribution uniformity degree of explosion energy in an explosion region during the blasting cartridge arrangement period and how to maximize the gradient value of comprehensive energy of adjacent blast holes during the initiation order arrangement period.

Description

technical field [0001] The present invention is aimed at rock blasting. Under certain conditions of explosives and rocks, how to achieve optimal crushing of rocks in the blasting area, maximum use of blasting energy and blasting by rationally designing the overall blasting area, rationally arranging explosives and rationally arranging the sequence of initiation of blasting under certain conditions of explosives and rocks. A rock blasting technique with the best results. [0002] Background technique [0003] The latest development of rock blasting technology in today's world is the large-area differential blasting technology, and the large-area differential blasting technology is the most advanced hole-by-hole blasting technology of Orikai Company. However, for a long time, domestic and foreign rock blasting theories have not had a clear understanding of the optimal rock blasting principle. Therefore, in the blasting design, technicians do not know in which state the rock i...
