Traitement d'un terril en combustion par confinement

Abstract : The Houillères de Lorraine coal fields have to engage works to confine a coal washery spoil heaps which was self-heating for few years. The coal waste (3,5 millions m3 ) was located at the bottom of a great sand quarry. Environmental hazards were due to the harmfull gas emissions, rich in carbon monoxide, during winter thermal inversion. The treatment had been chosen after analysis of the surface temperature by airbone thermographie study and after logging of internal temperatures in boreholes. The tip had been confined under 600 000 m3 of sand mainly extracted directly in the old quarry.
