    摘要: The frequency response of the cutting tool of a coal mining machine is monitored at a resonant frequency of the cutting tool, using a vibration transducer mounted on a non-rotating support arm, to detect the difference between coal and rock or other enclosing material. The horizon control sensor maintains the mining machine within the undulating coal seam.

    摘要: Methods and systems for automatically operating a continuous mining machine. One method includes automatically operating at least one actuator to position a platform supporting a cutterhead at a predetermined starting position and automatically operating the at least one actuator to advance the platform toward a cutting face until the cutterhead contacts the cutting face and at least one indicator of a physical force between the cutterhead and the cutting face exceeds a predetermined value. The method also includes automatically saving at least one coordinate of the cutting face to a computer-readable medium, the at least one coordinate based on a parameter of the at least one actuator when the indicator exceeds the predetermined value.

    摘要: Probes attached to the moldboard blade penetrate in situ formations while digging with a continuous excavator, thus enabling the direct and simultaneous sensing of characteristic strata property data signals both above and below the digging depth of the excavator. The data signals are evaluated to provide a reference for control of the digging depth so that product contamination by parting material can be minimized while mining, as well as the loss of product while removing the parting material.

    摘要: A drum cutter for a mining machine includes spaced-apart pick elements projecting radially therefrom and a disc forming part of a sensing apparatus disposed to follow a preceding one of the pick elements through rotational movement of the drum cutter. A disc is mounted by a pivot pin extending generally parallel with the rotational axis of the drum cutter. A sensor responds to the radial loading on the disc and produces a signal delivered to a controller for an actuator coupled to a pivot arm carrying the drum cutter. The disc is mounted to project radially about 10-20 millimeters beyond the radially-projected distance by a pick element. The sensor is a strain gage, a piezoelectric gage, an induction gage, a capacitive gage or a load cell. The sensor may be mounted within a hydraulically-power piston and cylinder assembly forming the actuator for the pivot arm. When a load cell is used, it filters out and detects pressure variations at peak magnitudes occurring as the disc penetrates the mine face with a rhythmic rotation for producing corresponding electric signals that are delivered to the controller for the pivot arm.
