Description

Technical Field

[0001] The utility model relates to the technical field of liquid oxygen explosion, in particular to a liquid oxygen explosion segmented detonation device with good safety. Background Art

[0002] Liquid oxygen blasting detonator is a device that uses liquid oxygen as an oxidant, mixes with combustible materials and then ignites and detonates. It is mainly used for large-scale rock or structure blasting in the fields of mining and construction. The working principle of this device is based on the high energy release capacity of liquid oxygen, which can generate a large amount of high-temperature and high-pressure gas in a short time, thereby achieving the purpose of quickly destroying rocks or hard structures. Segmented detonation refers to sequentially detonating explosives at different times and locations. Such a design can more accurately control the direction and range of the blasting, reduce unnecessary damage and improve safety. By controlling the detonation time and location of each segment, the blasting effect can be effectively optimized.

[0003] Traditional liquid oxygen blasting equipment usually adopts a single blasting method. Although this method can achieve basic blasting tasks, it has problems of high safety risks and low blasting control accuracy. Especially in complex geological conditions or when the blasting effect needs to be precisely controlled, the single blasting method is difficult to meet modern engineering needs. In addition, traditional equipment also has shortcomings in operational safety. Since all blasting points are detonated at the same time, once an accident occurs, the consequences are often more serious. The introduction of segmented detonation technology is to improve the safety and controllability of blasting. By finely controlling the blasting sequence, not only can the blasting order be adjusted according to the actual geological conditions, but also the safety accidents caused by misoperation can be effectively reduced, thereby significantly improving the overall safety and efficiency of liquid oxygen blasting.
