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.
矿山测量是矿产资源开发过程中不可缺少的重要基础技术工作。它在矿山从勘探、设计、施工、生产到关闭的整个生命周期中发挥着重要作用,被称为“矿山的眼睛”。随着卫星技术、计算机科学、人工智能、机器人技术、时空大数据等技术的快速发展,以空间信息技术为支撑的矿山测量科学技术日益发挥着“矿山大脑”的作用。本文系统地总结了矿山测量科学技术在当代和未来矿山发展中的特点。首先,基于现代矿业安全、高效、绿色发展的要求,分析了智能采矿方法的创新实践;其次,解释了区域经济和矿业经济一体化向产业链延伸和科技创新的转变。针对智能采矿,本文从三个技术维度进行了探讨:(1)通过建立矿山的时空数据模型,实现对生产系统的实时感知和远程智能控制;(2)透明矿山三维地质建模技术显著提高了地质条件预测的准确性和采矿决策的科学性;(3)通过整合多源遥感数据和深度学习算法,构建了高精度煤岩识别系统。研究进一步揭示了后采矿时代矿山测量的创新应用价值,包括:矿区地下空间的多元化利用(旅游开发、地热能蓄能、抽水蓄能等)、多平台遥感协同生态恢复监测、矿区土地空间优化规划等。实践证明,矿山测量技术是推动资源型地区绿色转型和高质量发展的重要技术引擎,对实现能源、经济、环境协调发展具有不可替代的战略意义。

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.
温度是煤自燃的主要原因之一。为提高阻燃性能,将CaCl2、聚磷酸铵(APP)和磷酸钙(CaHP)复配,通过物理化学协同作用控制煤自燃不同阶段的温度响应。采用热分析、热重傅立叶红外光谱(TG-FTIR)、原位傅立叶红外光谱(原位傅立叶红外光谱)和电子顺磁共振(EPR)等方法研究了煤自燃的多温度阶段协同抑制作用。结果表明,该方法是有效的。通过提前获取煤炭自燃反应阶段的特征,配置合适的复合抑制剂的方法可以有效地实现对煤炭自燃温度响应的智能控制。长焰煤的燃点提高了37.15℃。气相产物的抑制率大于20%,官能团的抑制率大于30%。对自由基有良好的猝灭作用,能有效抑制·H、·HO、·O等活性自由基的氧化活性。研究结果为不同变质程度煤的温度响应型复合阻燃剂的研究提供了实验和理论支持。

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.
煤矿地下水库有助于解决西部生态脆弱矿区严重的水资源不平衡问题,但由于矸石变形、饱和度和采空区几何形状的耦合影响,地下水库的库容评价仍然具有挑战性。本研究通过自主开发的测试系统和理论模型,研究了不同岩性、粒度和含水量的破碎矸石的变形和孔隙演化。提出了平面微单元模型和三维空间结构模型来量化地下蓄水结构的蓄水系数和总库容。这些模型考虑了分层岩性、饱和诱发软化和空间分布应力条件的影响。将该方法应用于察哈苏煤矿地下储层,结果表明:在应力增大的情况下,储层系数呈指数级下降,单、双岩性结构差异明显。与平面模型相比,空间模型中的存储系数对应力集中表现出更强的弹性,进一步分析确定了影响长期存储性能的顶板裂缝距离和应力恢复时间的临界阈值。该研究为地下水库蓄水潜力评价提供了一个综合框架,为矿井水的可持续利用提供了理论支持和工程指导。

Coupled numerical modelling of high-voltage electric pulse (HVEP) rock fracturing using COMSOL and 4D-LSM 基于COMSOL和4D-LSM的高压电脉冲(HVEP)岩石压裂耦合数值模拟

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.
高压电脉冲(HVEP)岩石破碎由于其能源效率,已经证明了硬岩可持续压裂的巨大潜力。其物理压裂过程的瞬态性质和高破坏性特征使下伏破岩机制的实验研究具有挑战性。然而,现有的数值研究缺乏将电击穿现象与机械解体过程精确联系起来的综合模型。本研究将COMSOL电击穿模拟与四维晶格弹簧模型(4D-LSM)力学分析相结合,建立了HVEP岩石破碎耦合模型。模型构建的核心理念是将电击穿得到的等离子体通道温度场导入到机械求解器中,实现两个阶段之间的精确连接。验证的数值模型阐明了不同电参数下高压电场致碎裂的全过程。此外,还研究了围压和矿物粒度对破碎行为的影响。最后,通过25个电气参数组合的参数模拟,证明了电极间距优化在实现节能破岩方面的关键作用。这些发现为在深部资源开采和选矿工程中设计高效的HVEP系统提供了预测工具。
