Embodiment 1

[0017] The method of expanding pot blasting: 1. Select the detonation point, drill hole 2, and place the explosive 1 in it; 2. Put the detonator 3 into the hole as a detonating charge, and lead it out from the plastic detonator 4, and the plastic detonator leads out of the hole. 30-50cm outside; 3. Use the detonator lead 5 to lead to a safe place, and connect the detonator 6; 4. Use the detonator to send out high-voltage pulse sparks, and trigger the detonator of the plastic detonator through the firing end 7, so that the operator stands Implement expansion pot blasting in a safe place.

Embodiment 2

[0019] The method of deep hole network blasting: 1. Select the detonation point, drill the hole, place the explosives in it, and arrange it in a net shape; 3. Use a detonator lead 5 to lead to the detonator 6 in a safe place; 4. Use the detonator 6 to emit high-voltage pulse sparks, and trigger the detonator of the plastic detonator through the firing end 7, thereby realizing the deep hole network blasting.

Abstract

An explosion method includes selecting explosion place, drilling, arranging explosive in the deep hole, leading out by plastic detonating tube, connecting the plastic detonating tube to detonator by detonating fuse, and high-voltage pulse detonating by detonator. Its advantages are high safety etc.

Description

1. Technical field [0001] The invention relates to a blasting method and belongs to the technical field of blasting. 2. Background technology [0002] At present, people's common blasting method is, adopt fuse to connect fire detonator, detonate by lighting fuse. When a large number of mines in towns and towns adopt the method of expanding the pot for blasting, in order to save the length of the fuse and reduce the cost, a 30-50cm fuse is used to make the detonating charge, and the ignited detonating charge is thrown into the deep hole for detonation. This blasting method violates Article 5.6.1 of the "Blasting Safety Regulations" (HGB6722-86). When the deep hole is expanded, it is forbidden to throw the detonating charge into the hole. When the hole depth exceeds 5 meters, it is forbidden to use the fuse to detonate; In violation of clause 3.2.14, the length of the fuse should ensure that personnel can evacuate to a safe place after the fuse is lit, but it should not be sh...
