摘要：
The fragile ecological setting is a challenge for large scale coal mining in west China, where is a coal-rich and water-poor area. The study constructs a “mining eco-system”, integrated coal mining & groundwater & ecology protection, from eco-perspective. Based on the original eco-system constraint, it proposes a protection concept of “bionic coal & water co-mining” and the coordinated mode of coal-mining and groundwater exploitation and ecological protection; Following new roadmap including “isolation-diversion-control” technology, the “isolation-layer control” mechanism and “the groundwater funnel aggregation” effect are discussed. The bionic coal-water co-mining technology system has been set, which contains the partite-area design, reconstruction by isolation method and bionic-controlling. And the key technologies have been developed, involving layer fracturing-working face mining-layer grouting method and groundwater collection & management. The bionic control concept and roadmap of coal-water co-mining, as a green-mining solution, will be helpful to improve the ecological productivity for the ecological fragile areas of western China. © 2017, Editorial Office of Journal of China Coal Society.
