Study on a Portable Abrasive Suspension Jet Cutting Machine for Coal Mines

Abstract:

Hot cutting is strictly forbidden in coal mines, especially for those with high density of gas. As the only one cold cutting technology, abrasive suspension jet could be used in coal mines to solve the problem of cutting operation under hazardous environments. Based on the technology of abrasive suspension jet, this paper developed a portable cutting machine which is suitable for the dangerous and complex environment in coal mines. Experimental results indicate that the cutting machine could well meet the requirements of cutting operations in coal mines, such as machinery maintenance. Methods for monitoring the quantity of abrasive within the high-pressure tank and the wear of nozzle were also investigated. Safe cutting could be ensured by application of this portable cutting machine. Promotion of the technology would have significant social and economic benefits.
