Abstract
The authors substantiate applicability of type-design practice of geotechnical facilities by their complexity with a view to determining structure and contents of deformation monitoring. It is suggested to exercise the type-design practice using particular characteristics of geological, hydrogeological and geotechnical conditions of mineral mining. Based on the existing regulatory documents and considering the modern scale of open pit mining and the current dimensions of open pits, the system of particular characteristics is shaped for the assessment of open pit mining conditions. The multi-criterion analysis of influence exerted by the particular characteristics on the resultant complexity estimate of an open pit is presented. The deformation monitoring procedure for open pits depending on their mining complexity is proposed. The procedure is tested at Tsentralny open pit mine at the Khibiny apatite-nepheline deposit on the Rasvumchorr Plateau.
