The location accuracy of the atomic blast hole 2 is improved by combining manual diving exploration with GPS data.

[0033] S2. Drill a new blasting hole 1 between adjacent original blasting holes 2. When drilling the new blasting hole 1, guide the drill sleeve through the auxiliary tooling. Use the auxiliary tooling to guide the drill sleeve to improve the accuracy of the new blasting hole 1 to ensure that the established blasting target can be achieved.

[0035] S4, detonating the explosive in the new blasting hole 1 by means of a lightning cable, so that the explosive in the original blasting hole 2 detonates due to the explosion of the explosive in the new blasting hole 1.

[0036] S5. Determine the amount of explosives to be exploded by detecting the vibration amplitude to confirm whether all the explosives in the original blast hole 2 have exploded. By drilling a new blast hole 1 between adjacent original blast holes 2 and loading explosives, the explosives in the new blast hole 1 are detonated to cause the explosives in the original blast hole 2 to explode, and then the new blast hole 1 and the explosives in the original blast hole 2 are used to jointly complete the predetermined blasting target, and at the same time, the explosives in the original blast hole 2 are cleared to reduce safety hazards.

[0046] The location accuracy of the atomic blast hole 2 was improved by combining manual diving exploration with GPS data.

[0047] The driving rack 41 drives the driving gear 51 to rotate, and the driving gear 51 drives the screw 52 to rotate, thereby driving the moving block 53 to move, so that the guide guard plate 54 moves to the corresponding position, so as to accurately guide the drill sleeve.
