Title: Water-jet-assist cutting evaluation and cutting trials. Research report (Final)

Abstract

Mining coal using the longwall method is becoming increasingly popular in the United States. Unfortunately, the dust levels liberated by various longwall equipment can exceed the permissible limits and therefore reduce the productivity. In 1984, the Eickhoff Corporation was awarded Contract no. J0145039 to build and demonstrate a water-jet-assisted shearer for the multiple purpose of reducing the dust levels, increasing the material size, and improving the bit service life. Two shearers were built, of which one was operated for two panels in a United States mine. Dust measurements and bit wear measurements were conducted and included in the report. The levels of the respirable dust were reduced by up to 52% and the service life of the bits was increased due to the cooling and lubricating effect of the water jets.
