Collapsing coal mine tips have been the cause of serious accidents.

The landscape around St Austell is scarred by clay mining tips (right).

They create a dark brown leaf case, composed of a single piece of leaf (mined tip of a leaflet).

Chemical and isotopic (C, S) analyses were performed on water sampled from upstream and downstream of the mine tips.

In the Nord-Pas-de-Calais region (France), coal mining activity has induced a build-up of many mine tips.

Coal mine tips, pyrite, sulfates, metals, d34S, 14C activity, bacterial activity, radiomagnetotelluric method, permeability.

Finally, to assess the degree of rainwater seeping through the coal mine tips, two radio-magnetotelluric surveys were carried out in September and November, 1999 following rainy periods.

He created a new system to collect, organize, investigate and data mine tips and complaints, tens of thousands of which are received by the SEC every year.

It pupates in the mined tips from mid-May to late June, and the tiny adult emerges shortly thereafter from a silk-covered hole in or below the base of the dead bud.

Coal Mining Tip Haniel with an open-air theater (Amphitheater) and the Kreuzweg designed by Tisa von der Schulenburg and Adolf Radecki and opened in 1995.

The Eston Branch Railway line took virtually a mirror-image route, with a junction curving south-west into the large railway sidings of the Eston Mines Tip Yard and south-east up an incline to the Eston mines.
