Mining works in Burgundy-Franche-Comté

Mining activity has led to the digging of many works on the territory. Following the cessation of mining operations, most of these structures are abandoned and may pose risks to property and people. Mining works are classified into several types of works (wells, galleries, descents, etc.) and the accuracy of their location is indicated. A materialized work is a work that has actually been found on the surface and whose coordinates have been recorded by GPS (we know precisely where it is). A localized work is a work whose coordinates are known (archives or information of the operator) but with an uncertainty of positioning (we know about where it is). The data come from hazard studies carried out by Geoderis (*) and are always brought to the attention of municipalities so that mining hazard is taken into account in urban planning documents for the future management of space. (*) GEODERIS is a Public Interest Group (GIP) formed by the Ministry of Ecological and Inclusive Transition, BRGM and INERIS. It provides post-mine assistance and expertise to the state (central governments and decentralised services).
