- Abstract:
- This article examines the integration of artificial intelligence into documenting the geomechanical properties of exploration well core. Neural networks and the ChatGPT-4o language model were used to analyze core images. The study was conducted using over 100 core samples, with parallel comparison of artificial intelligence results and expert assessments. The artificial intelligence model demonstrates high accuracy in identifying intact core segments longer than 10 cm. Certain challenges in analyzing zones with metasomatites and intense fracturing are identified, due to the difficulty of recognizing subtle cracks and artificial damage, as well as errors in classifying rocks despite their visual similarity. The need for regular monitoring and updating of the model to prevent the degradation of its predictive capabilities is noted. The use of artificial intelligence technologies significantly reduces the labor costs and resources required to identify key geomechanical parameters of core, while emphasizing the importance of close collaboration between geomechanics and programming specialists to create standardized and relevant research methods. Integrating artificial intelligence into core analysis processes significantly improves the efficiency, accuracy, and reproducibility of geomechanical documentation.

- Abstract:
- The article presents the results of studies aimed at solving the scientific and technical problem of protecting seam extraction roadways servicing high-load longwall faces under conditions of unstable surrounding rocks. It has been established that with increasing mining depth, the number of faces with a stable roof decrease significantly. It has been determined that the effectiveness of roadway protection under unstable rock conditions largely depends on the characteristics of the stress-strain state of the rock mass and the nature of its interaction with supporting structures. It is shown that the formation of zones of ultimate (limit) state around extraction roadways is determined by the combined influence of the strength properties of the surrounding rocks and the parameters of the applied support systems. It has been revealed that the behavior of supporting structures under ultimate deformation conditions follows a regular pattern and is governed by the ratio between their stiffness and the strength of the rock mass. It has been found that different combinations of the strength of supporting structures and surrounding rocks lead to the formation of failure zones that differ in configuration and scale. An assessment of the conditions of deformation of supporting structures and the development of failure in the surrounding rocks has been carried out. The regularities of the formation of failure zones around seam extraction roadways are presented. The research results may be useful for substantiating parameters and selecting support systems for seam extraction roadways in unstable surrounding rocks, as well as for developing measures to improve roadway stability in underground coal mining.

- Abstract:
- The article discusses existing methods and examples of developing new, more effective methods for gas extraction coal seams at the «Abayskaya» mine in the Karaganda coal basin. The high methane content of coal seams is the main obstacle to increasing production. Gas extraction coal seams reduces methane emissions in the mining area, and ventilation ensures that methane-air mixtures are diluted to safe concentrations. The use of gas drainage works during reservoir degassing becomes economically feasible due to their high efficiency.

- Abstract:
- It is known that short-delay detonation should help reduce the cost of explosives, reduce the seismic impact on objects, minimize destruction deep into the massif, as well as the formation of rock mass collapse. The purpose of the article is to develop a methodology for determining the explosion energy based on integrating the dynamic tensile strength of the rock over the depth of the well. To achieve this goal, a calculation scheme has been developed for determining the energy consumption for destruction without deceleration and pre-destruction, as well as with pre-destruction and deceleration for a rectangular grid consisting of four wells. The causes of incomplete crushing of the rock during a rectangular grid and a massive explosion are revealed, and the main provisions for eliminating this disadvantage due to pre-destruction during deceleration are indicated. The size of the savings of explosives due to pre-destruction during short-range detonation has been determined. The developed technique allows a more reasonable approach to the purpose of the specific consumption of explosives. The methodology takes into account the effect of the fracture area of a piece of rock on the energy consumption of blasting operations. The technique has been positively tested at the Kekura gold deposit in the Chukotka Autonomous Region.

- Abstract:
- A brief description of the problem of combating surface air leaks during artificial ventilation of underground mining enterprises is given. The aerodynamic processes in the mouth of a vertical air supply shaft during the injection method of general exchange ventilation of mine workings are considered. The features of aerodynamic processes at the mouth of the trunk are investigated under the specified operating modes of the main fan using physical and numerical modeling methods. During the physical modeling of aerodynamic processes, an inversely proportional dependence of the proportion of unproductive fan energy costs associated with surface air leaks on the velocity of the air jet emanating from the ventilation window was revealed. When numerically modeling aerodynamic processes using the universal ANSYS Fluent software, patterns of changes in the geometric and kinematic parameters of vortex zones and zones of organized movement at the mouth of the trunk were established depending on the velocity of air outflow from the ventilation window at an angle of 45°, which made it possible to appropriately interpret the results of measurements of static air pressure on the trunk model. Based on the results of the conducted research, a new method has been proposed to reduce surface air leaks during artificial ventilation of mines by injection method using guide plates.

- Abstract:
- The article presents the results of monitoring the condition of a building complex under construction in the complex engineering-geological conditions of Moscow using laser scanning technology. It has been established that combining high-precision laser scanning with traditional mine surveying-geodetic measurements allows for the creation of a detailed 3D model of the structure and for monitoring the displacements of its facade elements with high accuracy. It has been determined that this method facilitates the transition from point-based to comprehensive surface monitoring. The dynamics of deformation processes related to changes in the hydrogeological conditions and the manifestation of the barraging effect have been identified. A methodology for integrating laser scanning data into the mine surveying-geodetic monitoring system has been presented and tested. The research results can be useful for enhancing the accuracy and efficiency of deformation process control during the reconstruction and major construction of facilities in complex conditions, as well as for the rapid assessment of the effectiveness of protective measures.

- Abstract:
- This paper investigates the ground surface settlement induced by the construction of an underground pedestrian crossing using a pipe-roof structure beneath the railway line of the Moscow Central Diameter No. 1 near 29 Dmitrovskoye Highway. An analysis of soil settlement and the influencing factors at various construction stages was performed based on monitoring data. It was determined that the settlement was caused by insufficient soil compaction and the preservation of its structural properties, deviations from the planned sequence of construction operations, and the absence of void filling between the pipes and the surrounding soil. The study highlights the importance of comprehensive monitoring and preventive measures, including soil reinforcement and the use of stabilizing materials. The obtained results help identify the primary strategies for minimizing settlement and ensuring structural safety during construction in complex engineering-geological conditions. The recommendations provided can be applied to the design of similar structures.

- Abstract:
- The intensive development of the subsoil of Siberia and the Far East requires the equipping of mining enterprises with modern technology, including vehicles. A three-stage methodology is proposed for selecting vehicles for transporting rock to landfills after loading with excavators and other transportation operations. The first stage is preliminary in terms of the number of buckets unloaded by the excavator into the dump truck body. The second stage is the assessment of the required number of dump trucks at the quarry. The third stage is to check vehicles for traction characteristics at this quarry. The use of the proposed methodology will make it possible to exclude the acquisition of inefficient motor vehicles for this mining enterprise.

- Abstract:
- This article examines the role of energy in mining. Energy is considered a key factor influencing the efficiency of mining equipment and the overall enterprise. It is proposed to determine the efficiency of mining equipment by the amount of energy expended, i.e., to consider the efficiency of the energy system for specific types of mining processes. Insufficient research is noted on the energy implications of various mining processes and the lack of a unified classification of energy use. Formulas are proposed for determining the energy consumption of technical devices based on the shift productivity of the following mining equipment: bulldozers, front-end loaders, scrapers, and drilling rigs. The research results show that the efficiency of mining equipment directly depends on the amount and type of energy expended to perform specific operations. There is an optimal energy range for each mining process that achieves maximum productivity and minimum costs. Further, recording and analyzing energy indicators helps improve mining safety by identifying and preventing emergencies related to equipment overload or improper energy use.
