  • System for controlling cutting horizons for continuous type mining machines
    Patent number: 6666521
    Abstract: A control system for continuous mining machine to control the mining horizons of roof and floor horizons relative to the rock boundaries of an underground coal seam or ore vein. The mining machine is provided with a cutting drum mounted on a pivoted arm to allow for vertical displacement of the cutter to control the mining height. A plurality of sensors is carried on the rotatable arm to locate the roof and floor boundaries. Attitude sensors are mounted on the machine for providing signals indicative of the inclinations of the body of the machine, and, a microprocessor receives the signals from the boundary sensors and the attitude sensors for calculating the required roof cut and floor cut. A display device receives the signals from the microprocessor and displays the calculated results to the machine operator.

  • Control system for longwall shearer
    Patent number: 4634186
    Abstract: A control system for controlling the elevation of a cutter of a longwall shearer in which the attitude of the body of the shearer and the rate of change of attitude with longitudinal movement of the shearer are monitored and the elevation of the cutter is varied as a function of the sum of the product of a first constant times attitude and the product of a second constant and the rate of change of attitude.

  • Longwall shearer tracking system
    Patent number: 4466667
    Abstract: A tracking system for measuring and recording the movements of a longwall shearer vehicle (10) includes an optical tracking assembly (B) carried at one end of a desired vehicle path and a retroreflector assembly (A) carried by the vehicle. Continuous horizontal and vertical light beams are alternately transmitted at (38) by means of a rotating Dove prism (58) to the reflector assembly (A). A vertically reciprocating reflector (34) interrupts the continuous light beams and converts these to discrete horizontal and vertical light beam images transmitted at (68) at spaced intervals along the path. A second rotating Dove prism (64) rotates the vertical images to convert them to a second series of horizontal images while the first mentioned horizontal images are left unrotated and horizontal. The images are recorded on a film (74, 104). An overlay (106) with X and Y co-ordinates may be utilized to view the images and provide a graphical representation of the vehicle's path along the longwall coal face.
