Construction site
1) the heat reaction process is carried out in the inner cavity of the sealed tube body, the low temperature blasting, the CO2 of the jet has the function of inhibiting explosion and flame retardant, and can not explode the gas;
2) small vibration, no destructive shock or shock, greatly reduce the probability of induced gas outburst;
3) vibration and impact are unable to stimulate the heating device, thus filling, transportation and storage with high security;
4) the crack diffusion radius can reach more than 2m, which can reduce the number of the drainage holes;
5) the ability to control blasting, according to the use of the environment, the object of the different set of energy levels;
6) the coal forming block rate is high, the distance between the coal and the coal is short, the dust is small, and it is favorable for the production of large blocks of clean coal;
7) does not produce poisonous and harmful gas, hiding the gun from the near, can quickly return to the working surface, continuous operation;
8) the repeated use of the cracking device, life of up to 10 years
