A method to measure gas levels during auger mining of coal.
Pittsburgh, PA: U.S. Department of the Interior, Bureau of Mines, IC 9419, 1994 Jan; :1-7
The U.S. Bureau of Mines has developed a method to measure methane and other gases during the auger mining of coal. An intrinsically safe commercial gas detector with a built-in data logger was mounted in the center of the hollow conveying auger. A sample head through the wall of the auger conducted a gas sample to the detector. Results showed that gas levels can be monitored on a continuous basis during the auger mining of coal and the data retrieved upon completion of the hole.
