Continuous Mining: A Pilot Study of the Role of Visual Attention Locations and Work Position in Underground Coal Mines; A FailSafe Control System for a Mine Methane Pipeline; A Microcomputer Network for Mining Machine Control; Modified Tail Section Reduces Noise on a Continuous Mining Machine
Navigation and control of continuous mining systems for coal mining that will allow remotecontrolled operation of mechanized equipment normally used in underground roomandpillar coal mining, thereby permitting workers to be located away from the hazardous coal extraction area (the face). As part of this program, advanced machine

The sampling methods that were investigated can provide better ways to measure methane levels near the front of the continuous mining machine. In this report several practical guidelines are recommended for controlling and monitoring methane levels in the face areas of underground coal mines.
article{osti_, title = {Continuous mining machine}, author = {Wilcox, Jr, A G and Plumley, R D}, abstractNote = {A continuous mining machine is described comprising an elongated conveyor assembly for continuously conveying coal cut from a coal seam rearwardly away from the face of the coal seam being cut. The conveyor assembly has a frame structure associated therewith, power
Continuous Mining In underground mining, first and foremost in the modernization process are the machines that extract coal: primarily the continuous and longwall miners. First introduced in the late 1940''s, continuous miners provided a quantum leap in the speed and efficiency of extracting coal.

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.
The term quot;continuousquot; as applied to development machines has been one of the biggest misnomers used for mining equipment because, on development, they are usually anything but continuously cutting. The main delays mostly occur while roof support is installed and often waiting for shuttle cars to return from their discharge point for reloading.

coal can be properly loaded from the continuous mining machine into the continuous haulage machine. This task requires the haulage machine to maintain a critical position and orientation as it follows the mining machine. Positioning mobile equipment is not unique to mining. It is a generalized problem [3]. Research conducted by Sandia Labs
Shortwall mining, a method currently accounting for less than 1 percent of deep coal production, involves the use of a continuous mining machine with movable roof supports, similar to longwall. The continuous miner shears coal panels 150 to 200 feet (45 to 60 metres) wide and more than a halfmile (1 km) long, having regard to factors such as
