Coal mine degasification was originally developed to improve worker safety in coal mines, since explosive gas can form when methane mixes with air. Now, that gas can power the coal mine or be fed into the public power grid. The thermal energy can be used for heating purposes on-site, or be fed into a district heating system. And finally, mining companies can obtain additional revenues by selling Carbon Emission Reduction (CER) credits following the Clean Development Mechanism (CDM) or comparable mechanisms introduced among countries that have sighed the Kyoto Protocol.

The main technical challenge in using coal mine gas in gas engines is the fluctuation of methane concentration during operation, as well as variations in gas pressure, humidity and quality that can be observed from one mine to the other. Shenglis people took on this challenge 10 years ago and today is a leading supplier for such technology worldwide.

Use the coal mine, coal bed gas or mine gas, through the gas explosion-prevention ventilator, explosion-prevention mist transportation system, gas and liquid separator, coarse colander, extract colander and electromagnetism valve, to mix the gas with the air in the gas engine and then conflagrate the mixed gas, in order to drag the generator to generate electricity.
