Coal seam gas is high-quality energy and chemical raw materials.

Coal seam gas refers to the storage in coal seams with methane as the main component in the coal matrix to adsorb the particle surface the main part of divorced or dissolved in the pores of coal seam water and hydrocarbon gas, is associated mineral resources of coal, unconventional gas is nearly two decades on the rise in the international clean, high-quality energy and chemical raw materials. Commonly known as "gas", the calorific value of coal is 2-5 times more common, and one cubic meters of coalbed methane heat value equivalent to 1.13kg of pure gasoline, 1.21kg of coal, with a calorific value of natural gas equivalent, can be mixed with natural gas mixed transportation, and after burning very clean, hardly produce any emissions, is on a good industry, chemical industry, power generation and residential fuel.
