Problems solved by technology

Secondly, because the explosives explode in a "V" shape, the vertical blast holes greatly reduce the explosive force and can only shatter the surface of the rock, causing the shattered rocks to fly all over the sky, and safety accidents often occur
Obviously, this blasting technique is not safe, but also harmful to the operators, and it will also cost a lot of labor and materials and reduce the efficiency due to the stuck steel fibers, large consumption of explosives and detonators.

Embodiment 1

[0045] A safe, efficient and environment-friendly rock blasting method, which comprises the following steps:

[0046] 1) Determine the position and angle of the blast hole. According to the specific conditions of the mountain, determine the position of the blast hole at the foot of the mountain, and drill the hole with a slope of 5 degrees from bottom to top;

[0047] 2) Drilling and blasting holes, using a drilling device to drill holes, and the depth of the drilling holes is determined according to the mountain;

[0048] 3) To expand the hole, first put 200 grams of explosives and a detonator in the deepest part of the blasting hole to detonate according to the depth of the blasting hole. , and then scraped out the blasted rock slag, so many explosions, the deepest part of the blast hole will be exploded bigger and bigger, forming a bird's nest shape;

[0049] 4) For blasting, weigh an appropriate amount of explosives according to the size of the mountain and the blast hole...

Embodiment 2

[0051] A safe, efficient and environment-friendly rock blasting method, which comprises the following steps:

[0052] 1) Determine the position and angle of the blast hole. According to the specific conditions of the mountain, determine the position of the blast hole at the foot of the mountain, and drill the hole with a slope of 10 degrees from bottom to top;

[0053] 2) Drilling and blasting holes, using a drilling device to drill holes, and the depth of the drilling holes is determined according to the mountain;

[0054] 3) To expand the hole, first put 250 grams of explosives and a detonator in the deepest part of the blasting hole to detonate according to the depth of the blasting hole. , and then scraped out the blasted rock slag, so many explosions, the deepest part of the blast hole will be exploded bigger and bigger, forming a bird's nest shape;

[0055] 4) For blasting, weigh an appropriate amount of explosives according to the size of the mountain and the blast hol...

Embodiment 3

[0057] A safe, efficient and environment-friendly rock blasting method, which comprises the following steps:

[0058] 1) Determine the position and angle of the blast hole. According to the specific conditions of the mountain, determine the position of the blast hole at the foot of the mountain, and drill the hole with a slope of 15 degrees from bottom to top;

[0059] 2) Drilling and blasting holes, using a drilling device to drill holes, and the depth of the drilling holes is determined according to the mountain;

[0060] 3) For hole reaming, first put 300 grams of explosives and a detonator in the deepest part of the blasting hole according to the depth of the blasting hole to detonate, remove the debris after detonation, and then put about 570 grams of explosives and a detonator into the deepest part of the blasting hole to detonate , and then scraped out the blasted rock slag, so many explosions, the deepest part of the blast hole will be exploded bigger and bigger, for...

Abstract

The invention relates to the field of rock blasting, and specifically relates to a safe, efficient and environment-friendly rock blasting device. The rock blasting device comprises a blasting device, and a perforating device. The perforating device comprises a bracket, and an air compressor as well as a water tank arranged on the bracket. The air compressor is communicated with the water tank through a high pressure pipe. The water tank is further communicated with a drilling steel through the high pressure pipe. The air compressor is further connected with an air impact wrench through the high pressure pipe. The drilling steel is arranged on the air impact wrench. The drilling steel is of a hollow body, and the tip at the drilling head thereof is provided with a water outlet. The invention further relates to a safe, efficient and environment-friendly rock blasting method comprising the steps of determining a position and an angle of a blasting hole, drilling the blasting hole, enlarging the blasting hole, and blasting. The purpose of the invention is to provide the safe, efficient and environment-friendly rock blasting device and the blasting method. By using the device and the method, the most amount of rocks can be blasted with the least amount of detonators and explosive materials, and the blasting workers are prevented from being contaminated by the dust, thereby avoiding the occurrence of accidents, and achieving the energy-saving and environment-friendly rock blasting.

Description

technical field [0001] The invention relates to the field of rock blasting, in particular to a safe, efficient and environment-friendly rock blasting equipment and a blasting method. Background technique [0002] There are many mountains in the south of China. However, in order to stimulate economic development, it is necessary to build roads on rocky mountains. At this time, the mountains need to be leveled to facilitate road construction. Generally, the mountains can be dug directly with excavators. However, facing rocks In the mountain, direct excavation is obviously not feasible. At this time, rock blasting must be carried out before excavation. [0003] When blasting a rocky mountain, the traditional technology is to manually stand and operate the jackhammer to drill the blast hole vertically downward from the edge of the mountain top, and charge explosives to blast layer by layer. Although an air compressor is used to deliver high-pressure air to the blast hole throug...
