  • Method of and an arrangement for longwall mining
    Patent number: 4251108
    Abstract: Material removed from a longwall mining face is comminuted to obtain particles of predetermined size. A hydraulic fluid is circulated through the thusly obtained particles at a pick-up location so as to entrain and convey the particles from the pick-up location through a conduit to a separating location. At the separating location the hydraulic fluid is separated from the particles. The separated hydraulic fluid is recirculated from the separating location back to the pick-up location and into entraining contact with additional particles at the pick-up location.
