Smooth blasting is to adjust the blasting parameters of the peripheral holes, so that the explosion first forms a through fracture along the center line of each hole, and then causes the inner rock mass to crack and throw it toward the open surface.
Technical requirements for smooth blasting:
(1) According to the characteristics of surrounding rock, choose the minimum distance between surrounding eyes and the minimum Resistance line.
(2) Strictly control the charge of the peripheral eye, and the charge should be closed along the entire length of the blasting hole.The rational distribution, and the reasonable selection of explosive types and charge structure.
(3) Simultaneous detonation using peripheral eyes.
(4) Strictly control drilling operations, making it difficult to determine the positions and directions of the three blasting holes Correct, otherwise the effect of smooth blasting will be significantly reduced, and the light will not reach The purpose of surface blasting.
(5) The smooth blasting parameters such as peripheral eye distance E, minimum resistance line V, phase For distance E/V and charge concentration g, etc., engineering analogy or root Determined according to blasting funnel and seam formation test.
