Problems solved by technology

[0006] Adopt the gas blaster of above-mentioned detonator structure, existing problem is: 1, the thermal reaction material that needs to fill in the detonator needs to carry out the processing of processes such as material mixing, mixing evenly, rolling material or bagging, filling process It is time-consuming and labor-intensive, and the manufacturing cost is high; 2. During the filling process of the detonator, the oxidant and reducing agent are prone to uneven mixing, resulting in low heat release efficiency; 3. The thermal reaction material needs to be mixed and filled in advance. If the medium temperature is too high, it will easily cause combustion or explosion, which has great potential safety hazards; 4. Due to the damp, deterioration or deformation of the detonating material, it is easy to cause squibs, and it is impossible to determine the cause of the squibs, so it cannot pass The squib method eliminates potential safety hazards; 5. The detonation method of the existing gas blaster uses a solid activator to burn to generate high temperature, which directly conducts heat to the liquid carbon dioxide, causing the liquid carbon dioxide to gasify and expand, and the heat absorption efficiency of the liquid carbon dioxide is low; 6. The detonator The heat release rate is slow, the chemical reaction is insufficient, the heat release efficiency is low, the pressure of the liquid is relatively small after gasification, and the blasting power is small; 7. After the blasting, the reactants in the detonator produce a large amount of toxic and harmful gases. , such as hydrogen sulfide, sulfur dioxide, nitrogen monoxide, nitrogen dioxide and other gases, bring relatively large poisonous pollution to the blasting site
[0008] Yet the weak point that liquid oxygen explosive exists is: 1, it can only be used in open-air operation and building road and bridge, blasting building etc. If it overflows, it will cause pit gas and coal dust explosions in the mine and cause accidents; 2. Liquid oxygen explosives must be used as soon as they are installed, generally within one hour after they are made, otherwise the liquid oxygen will lose its effectiveness when it volatilizes; 3. The charging operation of liquid oxygen explosive is complicated and the safety is poor; 4. The blasting temperature of liquid oxygen explosive is too high, which is easy to cause combustion
[0011] According to the structural description of the above-mentioned existing gas blaster, it can be seen that two holes need to be opened in the plugging head with the gas charging and lead wire structure, which are respectively the filling port for filling and discharging the easily vaporized liquid and the lead wire for leading out the lead wire The problem of adopting this kind of structure is: 1. The plugging head with inflatable and lead wire structure, in the drilling process, the process is more complicated, labor-consuming and time-consuming. Larger, the sealing process is more difficult, and the problem of air leakage is prone to occur. If the hole diameter is small, the drilling will be larger and the drilling cost will be higher; 2. The lead hole needs to be filled with sealant, which is cured after sealing, and It is easy to cause deflation under high pressure; 3. High manufacturing cost
