  • Patent number: 5609397
    Abstract: A highwall mining system for mining aggregate material from a seam includes both a mining device for cutting aggregate material from the seam and thereby forming a drive in the seam and a conveying device for conveying mined aggregate material from the drive. The conveying device is formed of a plurality of modular conveyor units having a mechanism for releasably coupling together the conveyor units. A driving device is used for driving the mining device and the conveyor device into the seam to form the drive. A controlling device is employed to control forward movement of the mining device and the conveying device so that the mining device and the conveying device can move together at a predetermined rate of advance into the seam without there being any uncontrolled forward movement of the mining device and/or the conveying device in response to the incline of the seam and/or during the addition of a new conveyor unit to the conveying device.
