groundwater mining
2.WISMUT 2000 International Conference on Mine Rehabilitation”was held by WISMUT GmbH at Schlema,Saxony,Germany from July 11 to 14,2000.Technologies and managements of remediation and rehabilitation after close out of mine were emphatically exchanged on the conference,including 4 subjects:mine remediation/mine flooding/water pollution control/groundwater restoration,rehabilitation/post mining landscapes,tailings rehabilitation and innovative remediation technologies.
3.All of these provide a basically technological support to the determination of safety coal-rock pillar types and the reasonable height of coal-rock pillar to avoid groundwater rush during first level mining.
4.This paper analyses the main geo-ecological environment problems in light of neotectonics, ground subsidence, landslide, collapse, debris flow, groundwater environment evolution, change of land resources, cumulate castoff, etc. in the Shenfudongsheng mining district, discusses its influence on the ecological environment.
