我国井工煤矿降尘防爆及一体化防治技术展望

Advances and prospects in coal dust control and explosion prevention technologies

  • 摘要: 煤炭作为我国的主体能源,在其开采、储运过程中持续面临突出的职业健康风险与煤尘爆炸安全隐患,严重制约行业安全与可持续发展。为实现煤矿生产的本质安全目标,系统梳理了现阶段煤尘治理与爆炸防控的技术原理和作用机制,提出了以“源头治理、本质安全”为核心的煤尘降尘防爆一体化技术理念,并展望其未来发展。在理论研究层面,粉尘运移规律、润湿凝并机理及爆炸特性研究已形成系统性认识:粉尘扩散受风流−尘源−空间形态多场耦合影响;润湿性受官能团类型与粒径调控,凝并由惯性、扩散与静电机制协同支配;爆炸敏感性及强度参数则与煤尘含油量、粒径及环境条件密切相关。在技术研究层面,粉尘防控形成“源头降尘−过程控尘−个体防护”的全流程体系,爆炸防控则构建“防爆−抑爆−隔爆”三级防护链。基于上述理论与技术现状,进一步提出了以全过程协同为核心的降尘防爆一体化技术架构,旨在实现从粉尘源头控制到爆炸传播阻断的全链条覆盖。该架构重点围绕系统集成装备与多功能复合材料两大研究方向展开,致力于克服当前存在的感知决策基础薄弱、爆炸灾害链动态演化模型缺失、材料构效关系不明晰、环境适应性不足等关键挑战。未来研究应聚焦于多相介质与爆炸耦合机制的深化、环境自适应材料与智能传感器件的创新,以及构建“感知−决策−材料−执行”一体化智能协同系统。突破上述科学与技术瓶颈,有望系统推动降尘防爆一体化技术向可靠化、智能化方向发展,为煤炭工业实现绿色、安全、高效的高质量发展提供坚实基础,助力本质安全型矿山建设。

     

    Abstract: As the dominant energy source in China, coal mining, storage, and transportation continually face prominent occupational health risks and coal dust explosion hazards, which severely constrain the industry’s safety and sustainable development. To achieve the goal of intrinsic safety in coal mine production, this paper systematically reviews the technical principles and mechanisms of current dust control and explosion prevention technologies. It proposes an integrated concept of dust suppression and explosion prevention centered on “source control and intrinsic safety,” and outlines future development directions. At the theoretical research level, a systematic understanding has been formed regarding dust migration patterns, wetting and agglomeration mechanisms, and explosion characteristics: dust diffusion is influenced by the multi-field coupling of airflow, dust sources, and spatial configuration; wettability is regulated by functional group types and particle size, while agglomeration is governed by the synergistic effects of inertial, diffusional, and electrostatic mechanisms; explosion sensitivity and intensity parameters are closely related to the oil content, particle size, and environmental conditions of coal dust. At the technological research level, dust prevention and control have established a full-process system encompassing “source dust reduction, process dust control, individual protection,” while explosion prevention has constructed a three-tier protection chain of “explosion prevention, explosion suppression, explosion isolation”. Based on the above theoretical and technical foundations, an integrated dust suppression and explosion prevention framework centered on whole-process coordination is proposed, aiming to achieve full coverage from dust source control to explosion propagation blocking. This framework focuses on two main research directions: the development of integrated system equipment and multi-functional composite materials, to overcome key challenges such as weak sensing-decision foundations, a lack of dynamic evolution models for the dust accumulation-to-explosion chain, unclear structure-property relationships in composite materials, and insufficient environmental adaptability. Future research should focus on deepening the understanding of multi-phase medium and explosion coupling mechanisms, innovating environmentally adaptive materials and smart sensing devices, and establishing an integrated “perception-decision-material-execution” intelligent collaborative system. By breaking through these scientific and technical bottlenecks, it is expected to systematically advance the reliability and intelligence of integrated dust suppression and explosion prevention technologies. This will provide a solid foundation for the green, safe, and efficient high-quality development of the coal industry and contribute to the comprehensive construction of intrinsically safe mines.
