AP19680360 "Modeling of the stress-strain state of mountain massifs during the development of ore deposits based on complex geomechanical and geophysical studies"

Relevance

The project is relevant in the context of the intensification of underground mining in difficult mining and geological conditions, where the risk of geodynamic phenomena and emergencies increases. Modern technologies of geomechanical and geophysical analysis make it possible to improve the accuracy of assessing the condition of the mountain range, identify dangerous areas in a timely manner, and ensure the safety and efficiency of mining operations. The implementation of the project will contribute to the improvement of industrial safety, the sustainable development of mining enterprises and the rational use of mineral resources.

Purpose

To develop a technology for geomechanical assessment of the condition of the worked-out space during underground mining of solid minerals in difficult mining and geological conditions based on comprehensive geomechanical and geophysical studies

Expected and achieved results

Based on the application of modern technologies of the geophysical seismic survey method, a technology for studying the spent space of ore deposits will be developed, underground voids and stress-strain zones (VAT) near the void space are identified and modeled, the boundaries of the collapse zones of the overlying strata above the extinguished panels are new and the scientific significance of the research lies in the scientific substantiation of the possibility of predicting such consequences from the reliability of determining the nature of There are no detectable complications of the wave field and the boundaries of their zones of influence. The successful solution of the problem of localization of inhomogeneities will ensure the effectiveness of subsequent control over their interaction with the developed space.

Preliminary specialized studies have been conducted to substantiate the additional consumer properties and competitive advantages of the proposed technology. The following tasks have been completed:

• information has been collected on current subsoil users, their economic activities, including data on the deposits they are currently developing;
• a questionnaire for subsoil users has been developed;
• a survey has been conducted among subsoil users to assess the effectiveness and value of the proposed technology;
• it has been established (77% of respondents) that the use of seismic exploration at ore deposits is considered to have medium (46%) or high (31%) feasibility.
