ABSTRACT

Spontaneous combustion (SPONCOM) is a complex physical and chemical process involving several known and unknown variables which necessitates experimental detection methods and prediction hypotheses to minimize significant environmental pollution. Coal SPONCOM results in severe environmental pollution, safety threats, and substantial economic losses. This phenomenon has not only resulted into significant degradation of coal resources but also released a host of toxic substances, affecting both ecological integrity and human health in fire zones. Coal fire emissions have become a global concern and nearly all coal-producing nations have faced this problem for many years. Hence, it is important to monitor coal toward SPONCOM to prevent environmental contamination and possible safety hazards, as well as to avoid persistent and serious environmental pollution. This study discusses general questions on SPONCOM, such as: understanding, monitoring, preventions and management of SPONCOM on a global scale. Some remedial measures that are applicable to manage SPONCOM are reviewed. This will provide a learning exercise aimed to extend existing knowledge, current practice, and improving safety of the coal industry on an ongoing basis.

摘要

自燃 (SPONCOM) 是一个复杂的物理和化学过程，涉及几个已知和未知的变量，需要实验检测方法和预测假设，以尽量减少严重的环境污染。煤炭 SPONCOM 会导致严重的环境污染、安全威胁和巨大的经济损失。这种现象不仅导致煤炭资源严重退化，而且释放出大量有毒物质，影响着火区的生态完整性和人体健康。煤火排放已成为全球关注的问题，几乎所有煤炭生产国多年来都面临这个问题。因此，对 SPONCOM 的煤炭进行监测以防止环境污染和可能的安全隐患非常重要，以及避免持续和严重的环境污染。本研究讨论了关于 SPONCOM 的一般问题，例如：在全球范围内对 SPONCOM 的理解、监测、预防和管理。审查了一些适用于管理 SPONCOM 的补救措施。这将提供一个学习练习，旨在扩展现有知识、当前实践并不断提高煤炭行业的安全性。
