Geomechanics of the Development of Low-power Gentle Ore Bodies


Development of low-power ore bodies of complex structure deposits by underground mining method requires reliable ensuring of personnel safety by maximum consideration of existing geomechanical factors. Minimization of costs while preserving safe working conditions is the topic of numerous scientific publications, including this article. Methodology of the conducted study includes the analysis of activities on improving the efficiency of ore extraction by using hidden reserves at the underground mining of the deposits and the interpretation of the obtained results.
The characteristic of the current state of the underground mining of gentle low-power ore bodies, mainly the deposits of non-ferrous, rare and precious metals is given in the article. Efficiency analysis is provided concerning the application of the system of continuous development depending on the stability of enclosing rocks to minimize the losses in the pillars. The advantages of the options of continuous development system are detailed. The issues are considered related to ensuring safety in case of occurrence and propagation of the air wave.
Proposed and scientifically substantiated the algorithm which is related to the parameters selection of efficient technologies of the deposits development based on joint accounting of geological, mining and geomechanical factors. The method is recommended for determining the zone of dangerous effect of mining operations on the earth surface, and the measures of hazard prevention in case of collapse of the roof over a large area with monitoring by geophysical methods. The example is given concerning the calculation of permissible safe parameters of working space.
Efficiency of the underground mining of gentle shallow low-power metal deposits and, first of all, the safety of the personnel depends on the possibility of using rock properties to create load-bearing structures by ensuring geomechanical balance of the massifs.
