Mine surveying is an indispensable and crucial basic technical work in the process of mineral resource development. It plays an important role throughout the entire life cycle of a mine, from exploration, design, construction, and production to closure, and is known as the “eyes of the mine”. With the rapid development of satellite technology, computer science, artificial intelligence, robotics, and spatiotemporal big data, mine surveying science and technology supported by spatial information technology is increasingly playing the role of the “brain of the mine”. This paper systematically summarizes the characteristics of mining surveying science and technology in contemporary and future mining development. First, based on the requirements of safe, efficient, and green development in modern mining, an analysis is conducted on the innovative practices of intelligent mining methods; secondly, it explains the transformation of regional economic and mining economic integration towards lengthening the industrial chain and scientific and technological innovation. Regarding intelligent mining, this paper discusses three technical dimensions: (1) By establishing a spatiotemporal data model of the mine, real-time perception and remote intelligent control of the production system are realized; (2) Based on the transparent mine three-dimensional geological modelling technology, the accuracy of geological condition prediction and the scientific nature of mining decisions are significantly improved; (3) By integrating multi-source remote sensing data and deep learning algorithms, a high-precision coal and rock identification system is constructed. The study further revealed the innovative application value of mine surveying in the post-mining era, including: diversified utilization of underground space in mining areas (tourism development, geothermal energy storage, pumped storage, etc.), multi-platform remote sensing coordinated ecological restoration monitoring, and optimized land space planning in mining areas. Practice has proved that mine surveying technology is an important technical engine for promoting green transformation and high-quality development in resource-based regions, and has irreplaceable strategic significance for achieving coordinated development of energy, economy, and environment.

Temperature is one of the main causes of spontaneous coal combustion. To improve the flame retardant performance, CaCl2, ammonium polyphosphate (APP), and calcium phosphate (CaHP) were compounded to control the temperature response of different stages of coal spontaneous combustion through physical and chemical synergy. Simultaneous thermal analysis, thermogravimetric-Fourier infrared spectroscopy (TG-FTIR), in-situ FTIR and electron paramagnetic resonance (EPR) were used to study the multi-temperature stage synergistic inhibition of coal spontaneous combustion. The results show that the proposed method is effective. By obtaining the characteristics of the spontaneous combustion reaction stage of coal in advance, the method of configuring an appropriate composite inhibitor can effectively realize the intelligent control of the temperature response of coal spontaneous combustion. The ignition point of long-flame coal increased by 37.15 °C. The inhibition rate of the gas phase products was more than 20%, and the inhibition rate of the functional groups was more than 30%. It has a good quenching effect on free radicals and can effectively inhibit the oxidation activity of active free radicals such as ·H, ·HO, and ·O. The results provide experimental and theoretical support for the study of temperature-responsive composite flame retardants for coal with different metamorphic degrees.

Coal mine underground reservoirs help address the severe water imbalance in ecologically fragile mining regions of western China, but evaluating their storage capacity remains challenging due to the coupled effects of gangue deformation, saturation, and goaf geometry. This study investigates the deformation and void evolution of fragmented gangue with varying lithologies, particle sizes, and water contents through an independent-developed testing system and theoretical model. A planar micro-unit model and a three-dimensional spatial structure model are proposed to quantify the storage coefficient and total reservoir capacity of underground water storage structures. These models incorporate the effects of stratified lithologies, saturation-induced softening, and spatially distributed stress conditions. The methodology is applied to the underground reservoir in Chahasu coal mine, and the results show that under increasing stress, storage coefficients decline exponentially, with pronounced differences between single- and double-lithology structures. The storage coefficient in the spatial model demonstrate greater resilience to stress concentration compared to planar models, and further analysis identifies critical thresholds in roof fracture distances and stress-recovery times affecting long-term storage performance. This research provides a comprehensive framework for evaluating underground reservoir storage potential, offering theoretical support and engineering guidance for the sustainable utilization of mine water.

High-voltage electric pulse (HVEP) rock fragmentation has demonstrated substantial potential for sustainable fracturing of hard rocks owing to its energy efficiency. The transient nature and highly disruptive characteristics of its physical fracturing process render experimental investigation of the underlying rock-breaking mechanisms challenging. However, existing numerical studies lack comprehensive models that precisely link electrical breakdown phenomena with mechanical disintegration processes. This study combines COMSOL electrical breakdown simulations with four-dimension lattice spring model (4D-LSM) mechanical analysis to establish a coupled HVEP rock fragmentation model. The core concept of the model construction is to import the temperature field of the plasma channel obtained from the electrical breakdown into the mechanical solver to realize the precise connection between the two stages. The validated numerical model elucidates the full process of HVEP-induced fragmentation under varying electrical parameters. Furthermore, the effects of confining pressure and mineral grain size on fragmentation behavior have been investigated. Finally, parametric simulations across 25 electrical parameter combinations demonstrate the critical role of electrode spacing optimization in achieving energy-efficient rock fragmentation. These findings provide a predictive tool for designing efficient HVEP systems in deep resource extraction and mineral processing engineering.
