Control and management of geomechanical state and stability of structural elements of mining engineering elements in open-pit mines based on Big Data collection and analysis

When developing solid mineral deposits, mining companies face a large number of challenges related to the need of designing and implementing new efficient technological solutions to process information on the state of the mining engineering system. One of the ways to address these challenges is application of the Big Data technologies at all the field development stages. Big Date can ensure sustainable development of mining complexes and efficient management of geotechnological processes at all the mining stages. Among the most important processes in surface mining is the control of geomechanical processes that take place in the rock mass and that are recorded by the monitoring system. The article presents an approach to organising a multilevel integrated system for monitoring the stability of the near-wall rock mass of operating open pits based on Big Data collection and analysis. The proposed approach is based on accounting for (1) the properties and the state of the rock mass, (2) the scale level of the controlled structures. All kinds of data from different types of information sources should be collected in a single information system, where this information will be used for automated calculation of criteria for optimal operation of the mining engineering system. This approach is consistent with the concepts of hierarchical-block structure of the rock mass, within which the open-pit mining operations are performed and the open-pit excavation is created. Implementation of the proposed approach to control the stability of open pit walls requires equipping the mining operations with a wide range of monitoring and control equipment, organization of special geomechanical services, creation of a unified information system to analyze the Big Data, which will make it possible to ensure the required level of safety of surface mining operations.
