Study on the influence of geological structures on coal mining methods and the prospect of geological assurance technology for smart mining

Geological structures, such as faults, fractures, and sedimentary layers, play a key role in coal mining methods. These factors can affect the efficiency of mining operations, mine stability, worker safety, and mining costs. In the face of the energy revolution in the new era, smart coal mining is the only way to achieve high-quality development in the coal industry. Smart coal mining has brought new concepts to the mine geological assurance system and has promoted the development of higher-level geological assurance technology in coal mines. The importance of the geological assurance system in the entire coal mining process is systematically analyzed. The research status and application of surface, borehole, and four-while detection technologies are reviewed in detail. Key technologies and the development progress of intelligent geological assurance are introduced, and the future development direction of intelligent geological assurance systems is comprehensively considered. High-precision detection results are the foundation of geological assurance. Based on conventional three-dimensional seismic exploration technology, high-precision three-dimensional seismic imaging methods, intelligent identification methods for geological structures, intelligent inversion of layer parameters, joint interpretation of reflected and scattered waves for detecting small-scale geological anomalies, and key technologies for underground exploration are reviewed. In terms of building dynamic geological models, the dynamic detection technology of the coal-rock interface during mining based on airborne radar is proposed, and the importance of an online monitoring system is discussed. Based on the large volume of exploration data, real-time data processing and visualization software, and a method for dynamically updating three-dimensional geological models are established. This study systematically classifies the key technologies of coal mine geological assurance, identifies the future direction of intelligent geological assurance, and provides a reference for the development of intelligent geological assurance systems in coal mines.
