Mobile Water Cutting

Coal mine production has long faced significant safety risks such as gas explosions. The explosion limit of mine gas ranges from 5% to 15%, and cutting operations during mining are highly prone to causing combustion and explosion accidents. Data from the U.S. Mine Safety and Health Administration (MSHA) shows that between January 2002 and March 2012, approximately 379 methane ignition incidents were reported when using continuous miners and longwall shearers, highlighting the high risks of traditional cutting equipment in gas environments.

Three Major Pain Points in Coal Mine Cutting Operations 1. High Safety Risks Plasma cutting arc temperature reaches 16000-33000K Metal slag splashes over 3 meters Mechanical cutting friction sparks easily ignite methane ¹⁶ 2. Low Operational Efficiency Traditional pneumatic pick cutting of Φ22mm anchor cables: only 0.5 roots/hour per worker Roadway repair progress: less than 2 meters per shift ¹⁵ 3. Poor Environmental Adaptability Large equipment cannot access low roadways below 1.8 meters Humid and dusty environments increase equipment failure rates by 30% ²⁷

In mining machinery injury accidents, incidents caused by improper operation of cutting machines account for more than 15%. In high-gas mines, gas explosion accidents triggered by cutting sparks result in an average of 8 fatalities per incident and direct economic losses exceeding 20 million yuan. The dual demands for safety compliance and operational efficiency have driven the innovation and upgrading of coal mine cutting technology.
