Based on an analysis of the design principles and practice of underground mining of ore deposits, the most significant features, trends to develop and directions to enhance of underground geotechnology in the field of opening and preparation, mining systems, filling works and ore preparation have been established. The main signs of innovation - scientific research and implementation in production in order to obtain additional value, are highlighted. Various approaches to the development of innovative underground geotechnologies are shown and a methodology for their justification is formulated based on a systematic approach implemented in the framework of the concept of integrated development of mineral resources and on the principles of economic efficiency, industrial and environmental safety, completeness of subsoil development. The experience of the IM UB RAS on the development and implementation of innovative underground geotechnologies in the design and industrial operation of a number of ore deposits is given, which significantly increased the completeness and quality of ore extraction from the subsoil, increased labor productivity in sinking and stoping works, reduced capital and operating costs for ore mining and to utilize mining and processing waste in the mined-out space.
