Abstract
In the course of Bureau of Mines research, various methods have been developed to remove gas in advance of, during, and subsequent to mining. Such methods include the drilling of horizontal or cross- measure boreholes from a mine opening, and vertical boreholes stimulated for drainage in advance of mining or for gob gas drainage. Techniques and equipment now exist that allow for the drilling of a borehole at any angle to the vertical (and even along an arc). Stimulation treatments have also been developed that provide for increased gas production capability. This paper briefly describes the long-term production history of five select gas drainage installations.
