Carbon dioxide extraction device is filling metal tube, liquid carbon dioxide heater by repeated use of a high strength (the heating device), composed of constant pressure relief agency etc.. The device is arranged in the coal mining borehole, the use of detonator start heater, heating the liquid carbon dioxide becomes a gas pipeline pressure increasing compression constant pressure energy releasing mechanism, the constant pressure unloading can be broken, then release the volume expanded 600 times, carbon dioxide gas pressure reaches 100 MPa, for coal blasting. This is happening in milliseconds, fast speed and l release gas during blasting has a cooling effect, carbon dioxide is an inert gas, end can be avoided by blasting fire caused by gas accidents (gas explosion or gas burning), especially suitable for high gas and coal and gas outburst coal blasting, is conducive to the coal mine safety production. A new revolution in the traditional mining method for the rupture of the carbon dioxide bursting disc. For coal face, alternative to traditional blasting mining working face, coal blasting implementation, big power, throwing coal quantity, block, throw a short distance, reduce labour strength, and will not cause the collapse blasting accident. In addition to the high rate of coal blasting block, pulverized coal ratio decreased significantly, no dust, coal dust explosion hazard is greatly reduced. Coal mine application of this technology can bring about a substantial increase in production and profits greatly increased.
2, the rise of rock tunnels, trenches
No production of short wave and destructive vibration, suitable for sensitive area near the highway, geological hard, schools, residential areas, city population center area, sensitive explosive explosion limit and the prohibition, the subway project ideal mining equipment means.
3 underwater blasting
Widely used for deep-sea mining, rock sea lane widen and deepen the project. Submarine cable project, submarine pipeline trench installation engineering.
4 mixed soil demolition
Does not produce destructive short wave, does not destroy the strength to the place which the target explosive outside, the safeguard project safety is reliable.
5 stone mining
Directional cloth hole, not crushed rock, stone size control, suitable for the exploitation of large size of stone, more suitable for the exploitation of high-grade precious stones.
6 dredge drainage
Power plant boiler, rotary kiln, cement silo or pipeline dredge dredging. Can be used at the operating temperature of the equipment, fast K speed to clear the blockage, no need to stop cooling, greatly improve production efficiency, safety is very high
