Description

Technical Field

[0001] The utility model relates to the technical field of mine mining, in particular to a large-scale filling mining method mine segmented detonator storehouse structure. Background Art

[0002] Detonator is a main explosive material for underground blasting. Its function is to generate detonation energy to detonate explosives and detonating cords. Large-scale filling mining mines consume a large number of detonators every year. A blasting material chamber is set up in one panel area, and various detonators and sometimes explosives are stored in the chamber.

[0003] For example, the patent publication number is: CN 204238600 U, which discloses a detonator storage warehouse, including a passage formed by folded walls on both sides and a storage room, a warehouse roof located above the passage and the storage room, and the walls of the passage, the storage room and the warehouse roof include the outermost brick and concrete layer, the middle waterproof layer, which is formed by applying waterproof materials, and the inner layer of anti-radio frequency material coating, which is applied by anti-radio frequency material, and the anti-radio frequency coating is grounded. There are outer doors and inner doors at both ends of the passage. The detonator warehouse can play the role of anti-radio frequency, anti-static, waterproof and moisture-proof, and can effectively ensure the safe storage of the detonator warehouse, prevent accidents and qualitative changes of detonators, and ensure the safety of mines and mines. Although it can solve the problem that explosives cannot be stored safely, there are many single mine panels, many blasting material chambers, and the blasting material chambers are not standardized, which brings great management troubles and causes great safety hazards to mines.

[0004] The existing detonator storage chambers have many blasting material chambers in the plate area, the blasting material chambers are not standardized, and the management is difficult, which poses a great safety hazard to the mine; therefore, it does not meet the existing needs. In this regard, we propose a large-scale filling mining method mine segmented detonator warehouse structure. Utility Model Content

[0005] The purpose of the utility model is to overcome the defects and shortcomings of the prior art, provide a large-scale filling mining method mine segmented detonator library structure, and solve various problems existing in the prior art.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A large-scale backfill mining method mine segmented detonator warehouse structure, including a tunneling detonator chamber that is set up in segments at a suitable location near the mine segmented tunnel, the tunneling detonator chamber is a U-shaped passage connected to the segmented tunnel, one side of the tunnel is a detonator distribution area, the other side is a temporary waste storage area, and the end is a detonator storage area. The detonator storage area is divided into a plurality of storage rooms for storing detonators of different types by concrete brick walls, and the detonators are orderly discharged in each storage room by a placement rack. There are two duty chambers on both sides of the detonator distribution area, and an electrostatic release device is arranged in the detonator distribution area.

[0008] The detonator chambers are all supported by full-section reinforced concrete, the bottom plate concrete thickness is not less than 300mm, and the height of the detonator chamber bottom plate is not less than 300mm higher than the height of the bottom plate of the external mine segmented tunnel.

[0009] The ports of the segmented tunnels near the detonator distribution area and the temporary waste storage area are entrances and exits, and iron fence doors opening outwards are respectively installed at the entrances and exits.

[0010] The duty chambers are the issuer's duty chamber and the registrar's duty chamber. The issuer's duty chamber is located on the left side of the detonator issuing area, and the registrar's duty chamber is located on the right side of the detonator issuing area.

[0011] The electrostatic release device is a galvanized steel pipe arranged along the length of the channel. The bottom end of the galvanized steel pipe is buried 5 mm below the ground, and the bottom end is reliably connected to the power system grounding through a galvanized flat steel.

[0012] The storage rooms are located on both sides of the detonator storage area.

[0013] The placement rack includes a frame body, on which an array of circulating conveyor belts are arranged, and on which partitions are arranged, a detonator placement cavity is formed between the partitions, and each of the circulating conveyor belts is independently arranged and provided with a corresponding drive.

[0014] The two ends of the circulating conveyor belt are driven by driving rollers arranged at the front and rear respectively, and a driving handle is installed at the end of the driving roller near the middle of the detonator storage area in each storage room, and an identification plate for identifying the corresponding model is installed on the top of the placement rack.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. By selecting appropriate locations near the mine section tunnels to set up detonator chambers in sections, centralized storage and management of detonators can be achieved, solving the problem of too many chambers for blasting materials in the pan area.

[0017] 2. Through the excavation of detonator chambers, detonator distribution areas, temporary waste storage areas and zoning settings and structural distribution of detonator storage areas, the detonator storage area is divided into multiple storage rooms for storing detonators of different types by concrete walls. Two duty chambers are excavated on both sides of the detonator distribution area, which are guarded by dedicated personnel and require registration and strict management. This solves the problem of multiple blasting material chambers and non-standard blasting material chambers in the plate area.

[0018] 3. The detonators are stored on the storage rack so that they are placed on the surface of the detonator storage rack in an orderly manner. At the same time, each detonator is independent of each other. When the detonator storage rack is accessed, the detonator is placed in the corresponding detonator placement cavity according to the model. When taking materials, the person stands in the middle of the detonator storage area and only needs to shake the handle to take materials from the front end of the storage rack. At the same time, the staff in the duty room of the issuer and the duty room of the registrar will register and record them to confirm the access records of each detonator, which solves the safety problems caused by the irregular storage of blasting materials in the blasting material chamber.

[0028] Furthermore, the detonator chambers are all supported by full-section reinforced concrete, the thickness of the bottom concrete is not less than 300mm, and the height of the detonator chamber bottom is not less than 300mm higher than the height of the bottom of the external mine segmented tunnel 10.

The electrostatic release device is a galvanized steel pipe 8 arranged along the length of the channel. The bottom end of the galvanized steel pipe 8 is buried 5mm below the ground, and the bottom end is reliably connected to the power system grounding through a galvanized flat steel 9, which can play a good role in fire prevention and lightning protection.
