The interrelationship between the blast processes and geomechanics is studied as part of the synergetic interaction and interpreted as a research and technology concept with the trigger-effect features, with a view to prevent the undesired consequences inevitably accompanying the integrated industrial mining of the ore minerals. A synergistic effect is the result of two or more processes interacting together to produce an effect that is greater than the cumulative effect that those processes produce when used individually. The concept relies on the integrated approach based on geomechanical simulation of the safe ore minerals mining ensured by the reduced blasting impact, which is the most important factor of dynamic anthropogenic influence. The purpose of this study is to develop the methodology and algorithm for calculating changes of the stress-strain state of rock mass at the development of ore, coal and other mineral deposits, taking into account the trigger effect. A trigger problem is formulated for industrial operations in the geosphere. Solutions and approaches to solve the trigger-associated problem are shown. It was established that the selected computational approach is applicable for obtaining the adequate assessment of the seismic impact of explosion of charges of various designs, and the blast consequence forecasts. Optimization of the charge design for given mining conditions provides for significant improvement of the seismic performance indicators in the area of drilling and blasting. Explosive impact of the investigated charge designs on the stress-strain state of the rock body is identified and described. This supports the informed choice of the blasting parameters for reduction of the negative impact of blasts on the geo-environment. The concept has been tested in the context of large-scale mining operations, and its efficiency is assessed. The concept and proposed computational approach open up prospects for the future research and development in this knowledge domain.
