摘　　要：以石湖煤矿5号煤层为研究对象,通过构建全面的风险评估指标体系,采用模糊综合评判法、灰色系统理论和数值模拟方法进行风险评估,识别高风险区域和自然发火潜伏期。根据评估结果,提出了优化通风系统、实施降温与隔氧技术、使用防火材料与屏障等措施。结果表明,这些预防措施在降低煤层温度、瓦斯体积分数和自然发火事故发生率方面取得了显著成效,提高了煤矿的安全生产水平。Taking No.5 coal seam of Shihu Coal Mine as the research object,a comprehensive risk assessment index system was established.The fuzzy comprehensive evaluation method,grey system theory and numerical simulation were used to conduct risk assessment,identifying high-risk areas and the incubation period of spontaneous combustion.Based on the evaluation results,measures such as optimizing the ventilation system,implementing cooling and oxygen isolation technologies,and using fireproof materials and barrier were proposed.The results show that these preventive measures have achieved significant effects in reducing coal seam temperature,gas volume fraction and the incidence of spontaneous combustion accidents,thereby improving the safety production level of the coal mine.
