Abstract:Jining iron deposit buried in metamorphic rock of Jining group. Its depth is less than 1000m, and geological exploration depth in the past is over 1000m, while exploration this time can reach the depth of 2000m. The hydrogeological exploration holes have been specifically built with the hole depth of 1500m. On these basis, a pumping test has been carried out, hydrogeological parameters have been gained, and hydrogeological characteristics of metamorphic rock in Jining group have been identified primarily.
