Technology of underground reservoir construction and water resource utilization in Daliuta Coal Mine

in order to solve the problems of faile ecological environment and water resource shortage caused by igh strength and lagescale mining in Shendong Mining Area,based on the mine water disaster prevention and protecion and utilization,the key fechncolgies of underground reservoir yhich used the goaf as the ransfer.puicaton.storage and utilization of waler resources were put forward to protect water resources and recye.ling use the underground waler.By using above technooies,Daliuta CcalMine ad bilthe frst huge undergroundreservoir water resource protecion and recyeling use engineering system wth three-dimensional space network in China which ealized the eficientrecyceling of water resources t could not only solve the problem of mine food, but aso fiectivly protect the mine water rescurces,which could provide a new approach to green mining in shallow depth coal seam in our country.
