This article examines the experience of strategic cooperation between a mining software developer and a large mining company in adapting the Mining and Geological Information System (MGIS) to the company’s corporate requirements. The market-out of foreign MGIS from Russia placed large companies in a particularly difficult situation, as they had been building solutions based on imported software products for many years. The task of software import substitution in the mining industry, which deals with complex geotechnical systems, should be considered as a managed interdisciplinary scientific and engineering process requiring a systematic methodological approach. We note the importance of assessing the level of digitalization of existing business processes for engineering support of mining operations in forming a rational plan for software adaptation and modification. Given the requirement for a quick solution to the import substitution issue, we must consider the internal development of MGIS when coordinating with the industrial partner a work plan for functionality modification. This ensures the development of a competitive digital system for engineering support of mining operations not only for the company but for the entire mining industry. We present the main directions for modifying the MGIS functionality in the fields of geology, mine surveying, and geotechnology, along with examples of developed digital tools. We note that experts have mostly resolved the tasks of developing MGIS to meet the requirements of PJSC ALROSA, and the priority has become the development of software tools for medium-term and short-term planning of open-pit and underground mining operations. We provide a functional diagram of the planning unit. For the development of MGIS, we consider building the Mining Geological Digital Platform (MGDP). This platform provides the ability to create working tools (units) through the use of API functions and dynamic attachment of units to the MGDP system core.
The article presents the results of development for computer-aided design and planning of open-pit mines with the Mineframe software. There have been shown such peculiarities of computer-aided planning process as horizon reserves, development of annual cutbacks, searching of quarterly (monthly) volumes, monthly scheduling of equipment operation placed on benches, solution of the problems of ten-day periods, daily and shifts planning based on bench modeling.
The article described the methods for the use of specialized application of software on the stages of exploration, design, planning and maintenance of mining operations and also in abandonment or conservation of mineral resources deposits.
The system of automated design of mass explosions at open pits based on computer modeling of mining technology objects is presented. It is shown that the effective solution of the problem of automated design of mass explosions is possible with the complex solution of geological, surveying and technological tasks in a single information space of the mining enterprise.
At different times and by different authors, attempts have been made to relate the amplitude-frequency characteristics of the seismic signal to charge parameters, conditions of its detonation, and the size of the fracture produced by the explosion. To such attempts it is possible to refer results of measurement of parameters of stress waves at explosion in conditions of all-round compression, experimental and theoretical researches of speed of growth of cracks from explosion of a single charge in rocks. The dependence linking the frequency of medium oscillation with the Poisson's coefficient, longitudinal wave velocity and the maximum radius of the fracture zone is proposed.
Around the cavity formed in the rock mass, under conditions of high rock pressure, there is a redistribution of the static stress field. Near the contour of the cavity there are three zones: stratification (squeezing), unloading and support pressure.
