How many older pits were exhausted and closed by 1980?

The shaft was sunk in 1942 on the site of an older pit that had been abandoned almost 60 years earlier.

About 500 tons of coal per day was raised from the older pits.

The deep collieries replaced the older pits in the area.

Most of the old pits have flooded since they were shut down and are now used as bathing ponds.

The previous school was opposite the old pit and still stands now, only as a house.

It was a place never meant to loose a bull in; small like the old pit of sacrifice, with high walls to trap one.

I have the whole plan of the old pit still in my head.

Following the 1986 race, the old pits were torn down and a new international standard complex was built in its place.
