high efficiency armored belt feeder applied to coal using method

  • Longwall Top Coal Caving (LTCC) Mining Technology

    In cases of sticky coal, TCC in two lifts should be applied. First, a longwall face is developed at the horizon of the seam. After that, a second longwall face is developed at the floor horizon of the seam, and the coal remaining between the two faces is recovered by caving. Thick seams can be almost completely extracted using this method.
