[0033] A blasting method for a hole-separated pre-splitting blasting energy-gathering tube is disclosed. The swivel head 6 is aligned with a place where a hole needs to be drilled, and the hydraulic cylinder 2 is started to drive the motor 5, the swivel head 6 and the pressure cylinder 704 to move downward to contact the ground. The motor 5 is started to drive the swivel head 6 to drill a hole. After the swivel head 6 completes drilling, the hydraulic cylinder 2 is started to move in the opposite direction, so that the motor 5 and the swivel head 6 leave the ground first, and the pressure cylinder 704 leaves the ground later. Then, the blasting energy-gathering tube is placed inside the drilled hole, and explosives are loaded in the blasting energy-gathering tube, which is connected to a detonating device. Finally, personnel are evacuated to perform detonation.

[0034] When drilling holes, it is necessary to reduce the cracks around the drilling holes. The specific operations are as follows:

[0035] When it is necessary to drill a hole, start the hydraulic cylinder 2 to drive the hydraulic rod 3 to move downward, drive the first connecting plate 4 to drive the motor 5 and the rotating head 6 to move downward. Because the position height of the pressure cylinder 704 in the natural state of the spring 710 is lower than the position height of the lower end of the rotating head 6, the sliding block 701, the fixed pressure rod 703 and the spring 710 move downward, so that the pressure cylinder 704 will contact the ground before the rotating head 6. The spring 710 is compressed to exert a reaction force on the baffle 709, the sliding block 701 and the fixed pressure rod 703, so that the pressure cylinder 704 provides a uniform pressure on the ground. After the pressure cylinder 704 contacts the ground, continue to start the hydraulic cylinder 2 to move downward, so that the rotating head 6 contacts the ground, start the motor 5 to drive the rotating head 6 to rotate to drill a hole, thereby reducing local stress concentration. Stress concentration is the main cause of cracks. Uniform pressure can reduce the stress difference of the surrounding rock mass and reduce the possibility of cracks.

[0036] As the hole is deepened, spring 710 is continuously compressed, and the reaction force it provides becomes larger and larger. As the hole depth increases, the formation pressure on the hole wall also increases, which is caused by the weight of the upper rock and soil layer. As the depth increases, the required uniform stress also needs to increase to resist this increased formation pressure and reduce the possibility of cracks.

[0037] After the hole rotation is completed, the hydraulic cylinder 2 is started to drive the hydraulic rod 3 to move upward, so that the first connecting plate 4 and the first slide groove 8105 move upward, so that the first slider 8106 and the first push plate 8201 fixedly connected thereto move upward. Because point a of the second guide groove 8102 is farther away from the vehicle body 1 than point b of the second guide groove 8102, and point c of the second guide groove 8102 is closer to the vehicle body 1 than the central axis of the third guide groove 8103, when the second guide rod 8104 moves out from the inner side of the third guide groove 8103, the second guide rod 8104 moves out from the inner side of the third guide groove 8103. 4 can move to the side of the second guide groove 8102 away from the vehicle body 1, pull the second slider 8208, the second push plate 8202 and the limiting rod 8209 to move to the right side to the inside of the limiting hole 8207, limit the fixed plate 8206, the fixed rod 8205 and the sliding block 701, and then limit the sliding block 701, the fixed pressure rod 703 and the pressure cylinder 704, so that the pressure cylinder 704 still maintains a uniform stress on the ground. At this time, the hydraulic rod 3 continues to drive the first connecting plate 4, the motor 5 and the rotating head 6 to move upward, so that the rotating head 6 leaves the inside of the rotating hole and moves in the second When the guide rod 8104 moves to the point a, the second guide rod 8104 pushes the second push plate 8202 and the first push plate 8201 to move back, driving the limit rod 8209 to leave the inner side of the limit hole 8207, so that the sliding block 701, the pull rod 708 and the baffle 709 move back. Because the appearance structure of the first guide groove 705 is spiral, and the first guide groove 705 and the first guide rod 706 are matched in a clearance fit, the first guide rod 706 has a longer rising distance and takes a longer time, which can avoid the pressure applied. The pressure disappears quickly, thus causing cracks to form. When the rotary head 6 contacts the underground rock and soil, if the pressure cylinder 704 and the rotary head 6 are removed at the same time, it will cause a sudden stress release and form a stress concentration area. This sudden change will cause cracks in the hole wall. If the pressure cylinder 704 is released first, the drill bit is still in the rock and soil, leaving a cavity, which will cause the surrounding rock and soil to collapse or crack without sufficient support. The present device first removes the rotary head 6 and then removes the pressure cylinder 704, avoiding stress concentration in the surrounding rock and soil due to instantaneous stress release, thereby effectively reducing the generation of cracks.

One end of the second push plate (8202) is fixedly connected to a limiting rod (8209), and the limiting holes (8207) are equidistantly distributed on the inner side of the fixing plate (8206), and the matching manner of the limiting rod (8209) and the limiting hole (8207) is a clearance match.

10. A blasting method for a blasting tube with hole pre-splitting blasting according to any one of claims 1 to 9, characterized in that: The rotating head (6) is aligned with the place where the hole needs to be drilled, and the hydraulic cylinder (2) is started to drive the motor (5), the rotating head (6) and the pressure cylinder (704) to move downward and contact the ground. The motor (5) is started to drive the rotating head (6) to drill the hole. After the rotating head (6) has completed drilling the hole, the hydraulic cylinder 2 is started to move in the opposite direction, so that the motor (5) and the rotating head (6) leave the ground first, and the pressure cylinder (704) leaves the ground later. Then, the blasting energy-gathering tube is placed inside the drilled hole, and explosives are loaded in the blasting energy-gathering tube, which is connected to the detonating device. Finally, the personnel are evacuated to perform detonation.
