Problems Encountered in Dewatering a Nigerian Coal Mine

The only functional underground Coal Mine in Nigeria is located in Enugu in Anambra State. For some years now the mine has been beset with a perenial problem of flooding. This has hampered produc- tion and some time ago the mine was abandoned. Recently money and equipment were made available to reactivate the mine. Attempts are now made to increase production as it is very much below demand. However, there are problems as the mine is below the water table under some major rivers and any advance exposes men and equipment to water surge. The paper traces the different attempts made to dewater the mine and the problems encountered in producing coal in this mine.
