Research Of Water-inrush Mechanism In Shen Nan Mining Area

Shennan Mining District is located southeast of the southern Ordos plateau zone bordering Mu Us Desert and the Loess Plateau, the main coal seam buried generally shallow Quaternary loose burnt rock aquifer and aquifer overlying the coal seam widely distributed rich water very uneven, there is a potential collapse of sand water inrush conditions. In the exploitation of coal resources, is bound to affect the scope of mining disturbance led to coal seam roof unconfined aquifer water leakage in the aquifer water rich and strong sector, once diving directly into a water-filled mine water, will cause sudden Face water inrush of water or water and sand all collapse under the sand and other geological disasters, is currently the major risks that threaten regional mine safety production.In this paper, the Shennan Mining District for the study(including Hongliuling,Ningqiaota and Zhangjiamao oil field), through the collection of existing geological and hydrogeological data, analyze geological conditions in the region, structural factors, including characteristics aquifuge etc., on the basis of field tests on the mine water from the water-filled,water-filled channel research and other aspects of the mine water filling factors comprehensive study results caused by mine water inrush of water flowing fractured zone spatial distribution characteristics, the use of numerical simulation method, comprehensive analysis of the mechanism of water inrush of Shennan Mining area. According to the risk of water inrush comprehensive hydrogeologic analysis of the study area is divided mine, for possible water damage area delineation and prediction research results have certain application value and theoretical guidance for prevention and treatment of mine water district work.
