Description

Technical Field

[0001] The utility model relates to the technical field of blasting mining equipment for ore bodies and rocks, in particular to a blasting mining device for converting gas into air energy. Background Art

[0002] Mining technology refers to the mining technology of valuable natural mineral resources by manual or mechanical means. According to the different burial depths of the ore deposits and the requirements of technical and economic rationality, mining technology is divided into open-pit mining and underground mining. Open-pit mining is used for parts close to the surface and shallowly buried, and underground mining is used for deep parts.

[0003] Open-pit mining is a mining method that uses mining equipment to peel off rocks and extract useful minerals in stages, either in open-pit on hillsides or in sunken pits, under open-pit conditions. Open-pit mining has many advantages over underground mining, such as fast construction speed, high labor productivity, low cost, good working conditions, safe work, high ore recovery rate, and low dilution loss. Especially with the development of large-scale and efficient open-pit mining and transportation equipment, open-pit mining will be more widely used.

[0004] Blasting technology is often used in mining, and rock aggregates are stripped in a step-by-step manner. The purpose of blasting is to blast out stones of qualified sizes as needed. The energy of the explosion of explosives will cause the rocks near the blasthole to be crushed. Explosives themselves are dangerous goods, which are inconvenient to store and require approval procedures. In addition, the blasting process causes environmental pollution, which is not conducive to environmental protection.

[0005] Therefore, how to provide a blasting device that is energy-saving, environmentally friendly, safe to use and used for material mining is a problem that those skilled in the art urgently need to solve. Utility Model Content

[0013] The beneficial effect of the utility model is that external combustion-supporting liquid oxygen can be introduced into the bag body through an inflation tube and diluted by the paper block, so that the paper block and the inside of the bag body are rich in oxygen, and the ignition head on the detonating fuse is electrified to generate sparks, instantly igniting the paper block to produce an explosion effect. Compared with traditional explosive detonation or detonator detonation, the preparation process is safer, there is no thick smoke after detonation, and pollution to the environment is reduced.

Both ends of the entire bag body are closed to ensure the oxygen concentration inside the bag body, which is convenient for detonation.

[0016] Preferably, the air outlet holes are arranged at intervals on the outer side wall of the inflation tube, and the air outlet holes are all located on the inner side of the bag body.

[0017] The resulting technical effect is that the liquid oxygen in the inflation tube is diluted into the paper block and the bag body through the air outlet, thereby preventing oxygen from leaking out.

[0018] Preferably, one end of the inflation tube is connected to a Dewar tank, and the Dewar tank is filled with liquid oxygen.

[0019] The resulting technical effect is: the Dewar tank is filled with liquid oxygen, which is a preparatory condition for the explosion of paper blocks.

[0021] The resulting technical effect is that multiple groups of paper blocks are connected in series by the inflation tube, which facilitates the connection of the multiple groups of paper blocks on the one hand, and facilitates the oxygen in the air outlet to enter the gaps in the paper blocks and be diluted by the paper blocks on the other hand.

[0022] Preferably, one end of the detonating fuse is fixed on the inflation tube, one end of the bag body is located at the bottom of the blast hole, and one end of the detonating fuse is located at the middle and lower area of ​​the bag body.

[0023] The resulting technical effect is that the ignition head is located in the middle and lower section of the bag body, which is convenient for instantaneous burning of the paper block, and the middle and lower section refers to the position relative to the installation in the blast hole.
