| Sumario: | In the mining district of Linares (Jaén, Spain) an important underground mining activity has taken place until the first 90's, based on the exploitation of metal sulphides related to a framework of veins within a granite batolith. Actually, the mining have been abandoned, leaving as a result an important number of voids (shafts, galleries and veins excavated). After the closure of the mines, as a consequence of the stopping of the drainage pumping operations, the potentiometric levels have risen and the majority of the artificial voids are currently flooded. It's necesary to quantify the mining voids volume for water reserve evaluation. The stimation of the mining voids has been carried out from digital image analysis of vertical sections planes of the exploitation works. There is a fraction of mines that haven't got vertical sections planes available. In this case, we have estimated the volume of voids from statistical study and linear regression functions, vein longitude versus voids volume. The total amount of voids calculated is 13,1 hm3. |
