| description | [Purposes] By taking the water inrush event of Jiaguo Coal Mine as an example, the control effects of regional geological structure and mine field geological structure on the water-bearing system of Taiyuan Formation in coal mine are systematically studied. The water-bearing system of Taiyuan Formation in the mine field is regarded as an independent hydrogeological unit. Geological structure controls and affects of the supply, runoff and drain conditions of the karst fissure water flow system of Taiyuan Formation in the mine field are investigated. [Methods] This research has been carried out by using hydro-chemical characteristics and analysis of D, 18O stable isotope contents, combined with fine field geological survey and observation of underground water gushing point. [Findings] It is confirmed that the water inrush source of Jiaguo Coal Mine comes from the supply of Wangtao River. It is predicted and verified by drilling that the karst fissure of Taiyuan Formation K2 limestone covered by loose sediment of Wangtao River is the water conducting channel of water inrush source. Controlled by the karst fissure water flow system of Taiyuan Formation in the mine field, the Wangtao River flows through the K2 limestone aquifer of Taiyuan Formation under the riverbed, and flows along the layer to the low-lying structure of the mine field depression, resulting in water inrush at the K2 limestone karst fissure of the main inclined shaft. This work provides a reliable basis for the prevention and control of mine water disasters in Jiaguo Coal Mine, and also provides an effective way for the identification of water inrush sources in mines. |
