Ground water and surface water create a range of problems in lignite mining utilizing surface mining methods. In order to create a safe and economic mining environment, it is essential to carry out mining after dewatering the rock mass surrounding the lignite mines by advance dewatering techniques. This paper briefly describes the ground water regimes including pressure gradients associated wit...

Abstract The impact of dewatering on lime mortars modified using brick dust was studied, as it is particular importance in conservation applications. Dewatering takes place when freshly mixed come into contact with a porous substrate, such or stone, during site construction. Since the process between mortar and its substrate can modify properties, understanding enables pozzolan-modified hydrate...

Sewage sludge proves to be difficult to dewater due to its composition and biological nature, and it is unsuitable for disposal with high moisture content. In the present work, sewage sludge is dewatered by the thermal compression, which shows unique separation advantages of various materials, and the effects of applied temperature and pressure on the dewatering performance are investigated. Th...
