Coal Mine Waterjet Cutting Machine
Coal mine waterjet cutting machines are specialized cutting systems engineered for the complex underground environments of coal mines, using high-pressure waterjets as the cutting medium. Their core strengths lie in the dual advantages of safety and efficiency.
With spark-free operation, waterjet cutting fundamentally eliminates the ignition risks associated with conventional mechanical cutting, making it ideally suited for high-risk conditions such as gas-outburst and high-methane mines. Featuring cutting precision at the 0.1-mm level and working pressures up to 300 MPa, the system enables rapid separation of hard rock, coal seams, and steel supports, achieving more than three times the efficiency of traditional pneumatic pick operations.
The application scope spans the entire coal-mining production process:
-
In hard-rock cutting, it precisely separates coal seams from surrounding rock, reducing resource loss.
-
During roadway trimming, it quickly corrects over-excavated or under-excavated sections, ensuring accuracy for support installation.
-
In emergency rescue operations, it enables safe dismantling and cutting without secondary damage, securing critical time for trapped personnel.
Beyond underground coal mining, the technology has expanded into tunneling projects, mine rehabilitation, and infrastructure works. It is suitable for coal mines, metal mines, and non-metal mines, and demonstrates irreplaceable technical advantages under special conditions such as high-gas and rockburst-prone mines.
