Mow Cop Colliery

In January 2002 Ralph Johnson e-mailed me and asked what I knew about the coal tunnel that ran under Mow Cop. Unfortunately apart from the information on this site I didn't know anything else. Ralph along with Len Kirkham, a mining engineer, were going to make a video of the inside of the tunnel and also lead a few teams of keen tunnelers through, I was invited and was informed bring a pair of waders.
Thursday 15^th January 7:00pm we all met on the car park at Woodcocks Well School car park, I soon began to feel under-dressed as the other 10 people donned complete all in one skin tight water proofs, and there was I jacket jeans and waders. I was reliably informed though that waders should be enough.
Off we set under cover of darkness, we didn't wish to alarm the residents, and more importantly we didn't want any minors seeing what we up to. Children have a peculiar habit of disappearing down holes given half the chance.
The tunnel had been opened up only a few weeks prior as Len Kirkham and Ralph had been asked to make a video, Len however had done a survey on the tunnel some 10 years previous.
We removed the stones that covered the tunnel entrance, or exit as the case would have been and climbed down into the darkness. I carried what was a pretty impressive spotlight/torch borrowed from my brother; the rest had miners helmets that lit the place up very well indeed.
The orange silt filled water only came up to my knees, which was quite a relief. We took a few photos and then started the steady trek through the tunnel, there were plenty of rocks under foot and the tunnel floor was very uneven so care was needed. I was surprised at the height of the tunnel it was at least 7ft high, it certainly didn’t look that high on the old photograph I have.

The tunnel itself is as straight as a dye and has 2 very slight inclines leading to the centre from both ends. What surprised me more was that 1/3 of the way in the tunnel we came across a circular extension. At first you could be forgiven for thinking that they had started to build an airshaft leading up, but this was very unlikely. This round part in the tunnel doubled the width of the tunnel, and was a perfect circle. The most likely explanation was that the horses were turned round at this point as the rest of the journey would have been down bank; and a man could have pushed the coal filled carts down to the break winding drum easily thus freeing the horses to go and fetch the next load. Len also informed me that the local coal miners at the time bred their own horses, Clydesdales being ideal for the job. They were stabled at Towerhill part way along the track in what was believed to be the engine house.
We continued to the end of the tunnel, this time going on the downwards slope to sealed end, just up from the Ash Inn; to my obvious disappointment the water started to get deeper. In fact I remarked on it's temperature at it seeped over the top of the waders. I was glad to turn round and start walking back.
The roof is a little unstable in a few places, probably where the roads pass over the top, the wall are covered in coal dust and hanging from the ceilings are straw stalactites that have been made up from years of dripping water. The tunnel has been nearly full to the top with water as you can see a very clear water line mark. There are the odd wooden sleepers that have been left scattered, apparently they were placed at an angle to each other to help keep them stable and the tracks parallel with the heavy trucks pushing down. As well as the usual brickwork, there are are a few places where the gritsone has been left, these makes small cavern like structures, 10ft high in places.

THE TUNNEL HAS KNOW BEEN RE-SEALED.
