Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
This paper introduces a new system utilizing carbon dioxide (CO2) to promote gas extraction and to cool a mining face. Based on the phase transformation characteristics of CO2, this system chooses CO2 as the secondary refrigerant to cool mining face; after absorbing heat from the mining face, low temperature CO2 is injected into goaf, cooling goaf and improving desorption of oxygen (O2) and methane (CH4); gas mixed with CO2 extracted from goaf is transported upward to a pressure swing adsorption machine to purify CO2; the separated CO2 is cycled back to a cooling system near the mining face and then injected into goaf, while the rest gas with high-concentration of CH4 is provided to generate electricity. This system is a big project which can accomplish the functions such as cooling mining face, promoting gas extraction and reducing greenhouse gases discharge. It reduces the probability of gas explosion, and also decreases the discharge of CH4 and CO2 which is conformable to the requirements of energy-saving and environmental protection.
