ABSTRACT: Utilization of Methane and Injection of Carbon Dioxide into Abandoned Previous HitCoalNext Hit Mines

Ishikari Previous HitcoalNext Hit field is the most gassy Previous HitcoalNext Hit field in Japan. There is no operating Previous HitcoalNext Hit mine in this Previous HitcoalNext Hit field. But there are so many abandon Previous HitcoalNext Hit mines in the Previous HitcoalNext Hit field. From these abandon Previous HitcoalNext Hit mines, methane has emitted into the atmosphere. This is a significant problem for global warming. Therefore, we have planed to use the methane emitted from the abandon Previous HitcoalNext Hit mines for small scale generator and inject the exhaust generated by the engines for electric generation into the gob area of the abandon Previous HitcoalNext Hit mines. Injected carbon dioxide into the abandon Previous HitcoalNext Hit mines is absorbed by Previous HitcoalNext Hit remained in the gob area and replaces methane absorbed by Previous HitcoalTop. In order to make it clear , displacement tests of methane by carbon dioxide were carried out at the lower pressure( less than 2 atm.). In this paper, the results of the tests and outline of this project are described.
