Drainage of gas has been practiced overseas for almost half a century. Peal advances in drainage of gas to combat high emissions became practicable in the late fifties and early sixties when the technology was standardised to use it under a variety of mining and geological conditions. Today methane drainage is practiced in the United Kingdom, Germany, France, Belgium, Poland, Czechoslovakia, Hungary, Ibmania, U.S.S.R., China, Japan, Canada, U.S.A. and Mexico. Australia entered the list of countries using gas drainage on 3rd March, 1980 when the first full scale gas drainage system was set up and commissioned at West Cliff Colliery to drain gas from the Bulli Seam. Methods used in Europe are different from those used in North America, Japan and Australia mainly because of the different mining methods and also because of the limited number of seams under extraction, relatively new coal fields, and comparatively larger distance between the seams. In spite of the difference in the technique, the basic aim is the same and that is to improve ventilation and reduce ventilation costs, alleviate dangerous gas accummulation, overcome outburst hazards and ultimately make mining safer and more efficient. Over the last decade, there has
