Background
Tower Colliery is located near the village of Hirwaun, in Glamorgan,
South Wales.
The colliery, established in 1864, has been linked in the past with nearby
mines, none of which remain operational.
Up to 14 seams have been worked at Tower Colliery and the neighbouring
mines within the lease area of Tower.
British Coal considered Tower to be surplus to requirements, because of
market constraints, and the mine was closed shortly before privatisation.
It reopened in 1995, when it was bought out by the management and men
who worked the colliery prior to nationalisation.
"A History of Tower Colliery" can be found on the colliery's
own web site, the link to which you can find on our "Links"
page.

The only seam worked at Tower is the Seven Feet/Five Feet, a combined
seam of several leaves which offers typically 1.3m of coal in a mined
section of 1.65m. The coal being mined is a low volatile, anthracite product.
The boundaries are mostly formed by faults and seam splits, and by a worked
out area to the north. There are also problems with water in the Bute
seam, to north west, which limits mining in that area.

The Present
|
|
The main coal reserves in the Seven Feet/Five Feet seam are contained
in the west of the present licence area.
Only four faces were laid out and planned in the western end of the working
area, which BC previously regarded as economically recoverable.
Tower Colliery has outline plans to work possibly another nine faces beyond
this limit, in coal classed only as mineral potential.
Exploration has been limited and little data is available.

Although there are reserves to the north east, they protect the main
mine drifts from damage, so can only be worked at the end of the colliery's
life.
Consultants have been called in to address the water problem in the Bute
seam and they recommended drilling and probable dewatering.
Tower Colliery would appear not to regard these measures as cost effective
when weighed against the amount of coal reserves which would be made attainable.
There are two other seams which offer mineable prospects; the Nine Feet
seam, 100m above the presently mined level, and, the Four Feet seam, a
further 30m above. Neither of these deposits appear as promising as the
currently worked seam.
Tower Colliery is working just one longwall single retreat face in a section
approx 1.6m, with three shifts per day.
Output is taken via conveyor through the surface drift and is treated
in an on site washery plant which was erected in the late 1980's.

Into the Future...

Future Prospects.
Annual output for the years 1998 to 2002 is a projected 0.57 Mt, with
a possible increase in manpower to 406 when the colliery attempts to mine
the economic areas of the Seven Feet/Five Feet to the west.
Due to exhaustion of the current seam, the mine's life is now very limited.
Tower Colliery's long term future seems to depend upon securing a long
term contract which would finance the investment required to access another
seam.
