Engineering Application and New Technology of Underground Mine Water Treatment

According to the problems existed of big capital construction investment and high operation cost for traditional underground mine water treatment techno logies, the authors introduced the characteristics and engineering application for five underground mine water treatment technologies, including mine water treatment te chnology in goaf, underground mine water treatment system patent technology, reverse osmosis hypersalinity mine water treatment technology, ultra magnetic separatio n of water purification technology and pressurized gas and water interacted flushing filter mine water treatment technology. On the basis of these new technologies and considering the particularity of the space of mining environment and the mining working faces variability, in order to improve the efficiency of the mine water treatment, t he authors put forward the future development trend and direction, modular, removable and detachable underground mine water treatment devices and combined mine water treatment technologies should be researched.
