Research carried out since 1971 on plugging oil wells penetrating minable coal seams has allowed for safe underground mining through wells and recovering heretofore unrecoverable coal reserves. Work conducted under this research has consisted of plugging 27 wells and mining through 7 of them. This report covers the day-to-day record of plugging 23 of these wells and mining through 6 of them.
