The patterns have been revealed of phase transformations of gas hydrates and the stress-strain state of the rock mass around the cavities artificially formed during the mining of solid minerals. The technology for extracting minerals has been implemented by synthesizing the geophysical, geomechanical and technological innovations, taking into account the creation of safe conditions for mining the minerals. To solve this problem, automatic remote monitoring for the state of the gas explosion hazard control devices has been conducted. The patterns have been obtained of phase transformations of clathrate gas-hydrate compounds during their formation or dissociation using nanotechnology of the crystal lattice destruction. For the first time, the process of nucleation of gas hydrate crystals using electronic-optical equipment at the nanoscale level has been studied. A methodology has been developed for calculating volumetric geophysical and geomechanical models, taking into account the mutually influencing elastic, plastic and rheological properties of the rock mass to create innovative technologies for mining solid minerals. The criteria factors for optimization of the newest technologies for mining solid minerals have been obtained. Approaches to modeling the peculiarities of geophysics and geomechanics of the rock mass behavior have been improved. The patterns of the course of electrothermal processes in primary thermocatalytic and thermoconductometric converters of concentration levels of hazardous gases into electrical information signals have been revealed. A technology has been developed for the artificial production of gas hydrates from coalmine methane for the purpose of its compact transportation in the solid state. The paper summarizes the social, technical-economic, geomechanical and ecological factors of the strategy for the development of mining solid minerals and substantiates the multi-vector areas of application of these technologies to solve basic probl
