A comprehensive method of landscaping opencast mining sites in Mediterranean and mountainous regions, at the end of seams of old underground workings, has been formalised and put into practice on old sites previously worked by the Gard and Hérault sector of the Bassin du Centre et du Midi Collieries (Charbonnage de France Group).

Analysis of the various data available concerning old underground workings in the vicinity of opencast workings, together with reconnaissance and land measurement, enables the preparation of a geological, hydrogeological and mining report of the sectors worked, as well as the preparation of a comprehensive inventory of the condition of all workings in a concession, some of which may be very old. These reports on the environment and location of mine workings lead to an analysis of long-term risks to persons or to the natural environment, as well as to recommendations for essential safety work prior to the statutory abandonment of workings, which precedes legal renunciation of the mining concession. .
