Influence of structural and tectonic properties on hydrogeological and geotechnical сonditions of deposits in the Republic of Uzbekistan

Abstract. The paper establishes structural and tectonic properties of deposits in order to assess hydrogeological and geotechnical conditions of their development (based on individual deposits in the Central Kyzylkum region). The research methodology involved selecting samples to determine physical and mechanical properties of rocks as well as analyzing and assessing structural and tectonic properties and their relationship with hydrogeological and geotechnical conditions when developing deposits. There were explored mine workings of deposits located in the southern ridge of Tamdytau, within the Auminza-Beltau, Auminzatau mountain ranges. The deformations locations were found to be confined to faults and contacts of lithological rock differences. There are two large groups of well represented faults in the ore field, as they relate to scale and fold structures: regional and local fault structures. The overburden rock mass is mostly tough and hard, but soft rock interlayers, carbonaceous clayey shales, and clay gouge with a thickness of several millimeters to 10–15 cm, accompanied by tectonic disturbances, reduce the massif strength.
