Abstract

Coalfield fires are considered a global crisis that contributes significantly to environmental destruction and loss of coal resources and poses a serious threat to human safety and health. In this paper, research related to the initiation, development, and evolution of coalfield fires is reviewed. The existing detection and control techniques of coalfield fires are also reviewed. Traditional firefighting is associated with waste of resources, potential risks of recrudescence, potential safety hazards, extensive and expensive engineering works, and power shortages. Recently, coalfield fires have been recognized as having significant potential for energy conservation and heat energy recovery. Thermoelectric power generation is regarded as a suitable technology for the utilization of heat from coalfield fires. The extraction of heat from coalfield fires can also control coalfield fires and prevent reignition leading to combustion. Technologies for absorbing heat from burning coal and overlying rocks are also analyzed. In addition, the control mode of “three-region linkage” is proposed to improve firefighting efficiency. Integrating heat energy recovery with firefighting is an innovative method to control coalfield fires.

煤田火灾，控制技术和热能回收的原因和检测：回顾

摘要

煤田火灾被认为是全球性的危机，它对环境破坏和煤炭资源的损失做出了重大贡献，并对人类安全与健康构成了严重威胁。本文综述了与煤田大火的发生，发展和演变有关的研究。还回顾了煤田火灾的现有检测和控制技术。传统的消防与资源浪费，潜在的复燃风险，潜在的安全隐患，广泛而昂贵的工程工作以及电力短缺有关。近来，煤田大火被认为具有节约能源和回收热能的巨大潜力。热电发电被认为是利用煤田大火产生的热量的合适技术。从煤田大火中提取热量还可以控制煤田大火并防止引起燃烧的重燃。还分析了从燃烧的煤和上覆的岩石中吸收热量的技术。另外，提出了“三区联动”的控制方式，以提高消防效率。将热能回收与消防相结合是控制煤田火灾的一种创新方法。
