ABSTRACT:
A mining machine that may be used in place of an auger miner that is much more energy efficient in transporting mined material from the cutting site to the mouth of the mine. The machine includes a non-rotatable body member with stabilizers, at least one rotatable pilot cutting head mounted in front of the body member and a shaft operatively connected to the cutting head for rotation thereof, and a conveyor assembly mounted behind the pilot head in operative association with the body member. The conveyor assembly includes a scoop disposed posteriorly of the cutting head and having a bottom portion abutting the floor and extending posteriorly therefrom at an angle of about 14.degree. or less, and having side members that funnel toward each other. The conveyor assembly further includes at least one auger section associated with the shaft located posteriorly of the pilot head and having a continuously decreasing flight diameter, and a conveyor belt disposed posteriorly of the scoop and extending to the mouth of the bore. Add-on sections are provided for mounting the conveyor belt as the mining machine progresses, the belt comprising an endless belt received by a take-up unit which lets out the amount of belt necessary given the distance of the cutting head from the bore mouth. More than one cutting head may be provided, with cutter bits disposed for engaging the bore floor and cutting any cusp left on the floor by the cutting heads.
