1 Hydrogeological Characteristics of Mining Area 1.1 Including (stratiform) water layer Analyze the past exploration and production data, divide the strata into 6 aquifers and 3 aquifers according to stratigraphic age, lithology, water content and burial conditions. ① Cambrian, Ordovician, limestone and karst confined aquifers; ② bauxitic mudstone aquifers of Benxi Formation in the Carboniferous; ③ limestone fractured karst confined aquifer in the Lower Carboniferous Upper Taiyuan Formation (L_ ( 1 ~ 4)); (4) the middle part of Taiyuan Formation of Carboniferous sand and mudstone was separated from water; (5) the limestone fractured karst confined aquifer (L 6 ~ 9) in upper Carboniferous Upper Taiyuan Formation; Mudstone aquifuge; ⑦ Permian Shanxi Formation sandstone fractured confined aquifer; ⑧ Permian upper and lower Shi box sub-group of sandstone fractured confined aquifer; ⑨ the third and fourth series of sand, pebble aquifer.
