Promotion of renewable energy in Rosia Career

摘要

This paper will present a renewable energy solution, using the potential energy of water results from the aquifer formations by dewatering the mining area of the Rosia Jiu in order operating safely of lignite deposit. In the perimeter of the Rosia Jiu the exploitation of lignite is realize in heavy hydrogeology condition, the quantities of waters comes from three different sources: (1) Surface water from precipitation inside the perimeter as well as the surrounding areas with positive landforms - a seasonal sources but can be torrential; (2) The water coming from aquifers with hydrostatic level to download free natural slopes of working career, and is collected and routed to specific work stations for evacuation pump stations outside the perimeter; (3) The water from captive horizons and horizon artesian pressure in layer V couch horizons are tension release by specific works, the water from this work are directed to the central station pumps. (4) The disposal of water from Rosia Jiu area is realize by some high capacity pumps station to the guard channel that are build on the contour perimeter, water that are disposal trough these to the Jiu river. The volume of water discharged from the perimeter Rosia Jiu in the one year reported to one extracted lignite tones is 6:1 m~3/tone.
