Nowdays mining rock most adopts blasting ,which damage stone seriously,The reason is that the fracture speed of granite category generally is 1500-1800m/s ,marble category is only 700-1000m/s,while the transmission speed of detonation is about 6800m/s,pin ammonium explosive transmission speed is 3800-4200m/s,blast black power with detonator,its transmit soeed is 1700-1900m/s,therefor the blasting method have serious damage to stone,moreover easy flammability,explosive and very unsafe,killed countless people ever.State control is very strict.

Static expand power can separate rock by low speed expand,but the reaction speed is very slow and easy affected by temperature.

Gas expand power invented by our company overcome the drawbacks above to some extent,gas expand power is fire-resistant,can bear impact,less dosage generate large amounts of gas within 10s,the transmission speed of detonation is only 400m/s,no damage to any stone and no detonation phenomenon.Security,speediness and not affected by temperature .It is a pioneering work in the history of mining

The power is widely applicable to backout indoor,construction dam,mining tunnel
