Abstract
The utility model discloses a multi-row differential roadbed deep hole blasting device, which belongs to the field of strip mine blasting construction, and comprises at least one blasting unit; the detonator is connected to the lead inlet of the blasting unit through a lead; and time delay devices are arranged on the conducting wires between the exploder and the blasting units, and the number of the time delay devices is equal to that of the blasting units. The utility model discloses a multirow differential roadbed deep hole blasting unit makes the cartridge bag explode at the different time, makes the explosion stress ripples stack each other, strengthens crushing effect.
Description
Technical Field
The utility model relates to a strip mine blasting construction field especially relates to a multirow discrepancy road bed deep hole blasting device.
Background
With the increase of the mining depth, the highest exposed side slope of the open-pit mining area exceeds 400m, the area of the lower part of the hard-blasting ore rock is increased, and the requirements on blasting vibration control and blasting quality of the hard-blasting area are also updated.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model aims to solve the technical problem that a multirow differential roadbed deep hole blasting device is proposed, makes the cartridge bag explode at different times, makes the explosive stress ripples stack each other, strengthens crushing effect.
To achieve the purpose, the utility model adopts the following technical proposal:
the utility model provides a multi-row micro-differential roadbed deep hole blasting device, which comprises at least one blasting unit; the detonator is connected to the lead inlet of the blasting unit through a lead; and time delay devices are arranged on the conducting wires between the exploder and the blasting units, and the number of the time delay devices is equal to that of the blasting units.
Preferably, the blasting machine further comprises a fixing plate, and the plurality of blasting units are arranged on the fixing plate in order.
Preferably, two or four clamping wing plates are arranged on the outer wall of the blasting unit in the circumferential direction, and the side surfaces of the clamping wing plates are attached to the outer wall of the blasting unit.
Preferably, the top end of the clamping wing plate is fixed on the fixing plate.
Preferably, the bottom surface of the grip wing panel is a slope such that the side of the grip wing panel facing the side of the blasting unit is longer.
The utility model has the advantages that:
1. the explosive charges are detonated at different times, so that the explosive stress waves are mutually superposed, and the crushing effect is enhanced.
2. The novel dynamic free surface is created, the rock clamping effect is reduced, the crushing degree and uniformity of the ore rock are improved, and the forward-impact and backward-impact effects of the blast hole are reduced.
3. The mutual collision between the broken pieces of the ore rocks after explosion can generate supplementary crushing, and the concentration degree of the blasting pile is improved.
4. As the corresponding blast holes are detonated at millisecond intervals in sequence, the seismic wave energy generated by blasting is dispersed in time and space, and the seismic wave intensity is greatly reduced.
