Vibro-sesismic to increasing the production rate of coal bed methane (view source)
Revision as of 14:11, 13 July 2015
, 14:11, 13 July 2015→The result of experiment
Based on vibro seismic effect on core sample where both frequency and amplitude act as the main parameter, shows that there is optimum condition that give maximum effect . And then the research continue with using nine various frequency and the final amount of each samples are counted in percent, there are :

Based on the data, we know that the value of optimum frequency is 10 – 15 Hz<ref name=Ariadji_et_al />
