Step 5. checkout gear that the opening device of hydraulic power source, gas suction pump, carbon dioxide shattered is connected with a controller.
10. the implementation method of the system that shatters for the coal seam under mine as claimed in claim 9, it is characterized in that, the two ends of described rupture diaphragm are provided with piston cutter and endless knife, and implementation method is as follows:
During work, by controller primer fluid potential source, the working media of hydraulic power source is entered continuously by pipeline and ignition hydraulic interface ignites space, the working media pressure ignited in space increases, promote isolated part to move to blast side, space, the liquid carbon dioxide pressure that set off an explosion in space increases, the end thrust being distributed in the piston cutter end of breakable parts increases, the shearing force of rupture diaphragm is increased, and be provided with endless knife at opposite side, produce the shearing force identical with the shearing force direction of rupture diaphragm; When the intensity that both shearing force sums produce is greater than the shear strength of rupture diaphragm, rupture diaphragm is broken, liquid carbon dioxide enters the Free up Memory of releasing parts, and concurrent looks is deformed into gaseous carbon dioxide and is outwardly discharged by radial release aperture, produces blast; Whether the carbon dioxide checkout gear that shatters shatters, if do not shattered, then from newly opening hydraulic power source for detecting the carbon dioxide device that shatters; If shattered, then open gas suction pump.
