Development Status of Mine Coalbed Methane Utilization in Yangquan Mining Area

According to the features of the large quantity coalbed methane drainage in Yangquan Mining Area, Yangquan Coal Mining Group actively promoted the utilization of mine coalbed methane. The coalbed methane was applied to the domestic fuel and the power generation. The gas- fired central air conditioning and the lar ge gas- fired boiler were developed. The coalbed methane was applied to the alumina calcination. The utilization of the coalbed methane could improve the utlization ra te of the coalbed methane, could save the fuel coal and could reduce the coal cinder and sO X emission quantity with obvious social and economic benefits. The paper provided the problems to be noted in the uiliation process of coalbed methane. The suitability between the combustion device of the large gas- fired boiler and the fuel gas should be well solved. The development of a large industrial project could realize the benign development circulation with the gas utilization to promote the gas drai nage.
