Safely and high-efficiently breaking rock is of practical significance.

Gas Cracking Filling Machine Non-detonating Blasting Rock Drill Blasting Contractors

Safely and high-efficiently breaking rock is of practical significance. In some engineering, explosive blasting may be restricted for its side effects. Traditional non-explosive methods like demolition agent and rock breaking machine are generally time-consuming. Therefore, this study proposes a novel liquid carbon dioxide rock-breaking technology and designs the relative device. The effectiveness, safety and high-efficiency of the proposed technology are investigated by shock pressure test, vibration site test and field rock breaking experiment. 


The experimental results show that the duration of the monitoring shock pressure is around 1500 μs. The shock pressure signal of liquid carbon dioxide tube breaking in free condition contains four stages, namely, increasing exponentially, decreasing oscillatory, stabilization, and negative pressure stage. As pressure sensor is set at 850 mm from the test tube radially, the shock pressure monitored increases to the maximum value of 115.7 kPa within 6 μs. During the liquid carbon dioxide rock breaking, the vertical component of the peak particle velocity of vibration is 173 mm/s, 85 mm/s and 35 mm/s along distance at 1.5 m, 2.5 m and 3.5 m from the tube, respectively. The Fourier power spectra results show that about 85% energy distributes at 6–60 Hz.


The vibration caused by the novel technology can meet the requirement of mainstream blasting safety criteria better than that of explosive blasting. Finally, the technology is successfully applied in rock excavation at a metro station construction site. The proposed liquid carbon dioxide rock-breaking technology is preliminarily demonstrated to be safer than explosive blasting and more efficient than traditional non-explosive techniques.


CO2, gas expansion fracturing is non-explosiver rock demoltion splitting machine, a result of physical volume change, it has not shock wave, vibration wave, blasting wave, etc. That means gas expansion forms from combined action of gas volume and pressure, instead of explosive.

Scope of application:

Any industry that uses traditional explosives can be applied, and special areas or places in non-civil explosion areas can better reflect its superior characteristics.

    1. Mining industry: mining of open pit mines and mining, mining, roofing and coal bunkers can be applied. Such as the elimination of the working surface, eliminating the impact of ground pressure, Shimen Jie coal, roadway bottom drum treatment, treatment of coal seam faults, dredging coal bunkers.

     2. Emergency rescue and rescue: road clearing, treatment of dammed lakes, removal of landslides, flood discharge, and reinforcement of dams. It is also an indispensable tool for mine rescue teams.

     3. Subways and tunnels and municipal works: blasting and excavation of tough rocks, directional blasting of urban concrete buildings, excavation of road trenches, etc.

     4, cement, steel, electricity and other industries: preheaters, rotary kiln, furnace kiln steel slag and other equipment and facilities clearing. Agglomeration treatment of garbage burning furnace in urban thermal power plants. The tower chassis reinforcement of mountain high-voltage lines.

     5. Geological exploration: field drilling sampling, various stone and mineral mining and cutting.

     6, high cold area: icebreaking, snow peak blasting, loose operation of various powdery blocks.

     7. Underwater engineering: submarine cable and pipeline trench excavation, submarine drilling and blasting, etc.
