  • Drill rig operator cab viewport
    Patent number: 6095263
    Abstract: A viewport is located in the floor of a drill rig operator's cab to enable a rig operator to view drilling operations. As drilling commences, the operator may view the material underlying the rig and make a visual determination that the coal seam has been reached, by identifying that the material has the characteristic black color of the coal. When the coal seam is reached, the drilling operation is then altered accordingly to prevent overdrilling.
