Developing an effective safety emergency plan for coal mines is crucial to prevent and reduce accidents, as well as improve the emergency response capability. This paper identifies and analyzes potential accident hazards in the Burtai coal mine through a comprehensive and practical investigation of risk factors. Based on a mathematical model of a mine fire disaster relief algorithm, the MATLAB software is used to conduct numerical simulations of the dynamic spreading process of the fire smoke. Several escape routes are determined based on the simulation results, including the main escape route at the working face of coal mining, the main escape route at the working face of tunneling, and the main escape route against the reverse wind in the main inclined shaft, the auxiliary adit, and the main air intake roadway. The results presented in this study can provide guidance for improving fire emergency escape and rescue plans of the Burtai coal mine.
制定有效的煤矿安全应急预案对于预防和减少事故，提高应急响应能力至关重要。本文通过对风险因素的全面、实际的调查，识别和分析了布尔台煤矿潜在的事故隐患。基于矿井火灾救灾算法的数学模型，使用 MATLAB 软件对火灾烟雾的动态扩散过程进行数值模拟。根据模拟结果确定了几条逃生路线，包括采煤工作面的主要逃生路线、掘进工作面的主要逃生路线以及主斜井、辅助进风巷和主进风巷的逆风主要逃生路线。本研究的结果可为改进布尔台煤矿火灾应急逃生和救援计划提供指导。
