A large sinkhole that forced more than 30 homes to be evacuated is still growing, a council leader has said. The void emerged on Nant Morlais in Pant, Merthyr Tydfil, on Sunday morning and council leader Brent Carter said on Monday that "more cracks are coming across the road and into walls and gardens". South Wales Police, South Wales Fire and Rescue Service and Merthyr Tydfil council were alerted to the incident just days after Storm Bert caused flooding across Wales. More rain fell overnight, just days after Storm Bert caused flooding across Wales, along with a coal tip landslide  https://www.bbc.co.uk/news/articles/c3wqjen1veqo and sinkhole, external at Cwmtillery, Blaenau Gwent.

After the 200ft sinkhole was found just behind Birley Moor Garden Centre It is believed the sinkhole may lead to Dent Main Colliery. Water had to be pumped out of the colliery into the Ochre Dyke when the collieries were open.

We are looking to find out more information about the flooded Collieries that run under Owlthorpe. Has anybody got copies of the plans of the workings of the Collieries that we could print online so residents of Owlthorpe can see exactly what is happening underground? Also how is the water pumped out of the Collieries after they closed, and who is responsible. This video https://www.ecological-owlthorpe.org/Ochredyke2.mp4 shows the ochre collaring in the Ochre Dyke water. The Coal Authority referred us to the Environment Agency: “This site is 1.5km upstream of main river (Environment Agency maintained river) it is outside of our remit from a flood risk perspective. The river here is classed as an ordinary watercourse and will be the responsibility of Sheffield City Council.” We are still investigating.
