摘要
基于对我国资源整合煤矿采空区灾害事故分析和采空区灾害类型分析,研究了采空区灾害的特点,提出了防治对策及建议。结果表明:按致灾形式划分,我国资源整合煤矿采空区分为废弃老采空区(井筒)透水、采空区火灾(含自燃、瓦斯爆炸等)、采空区有毒有害气体(含瓦斯)涌出、采空区诱发的不良地质异常灾害等4种类型;老采空区具有分布情况不明、灾害种类多样、隐蔽性和突发性、难以预测性的特点;总结提出了资源整合煤矿采空区灾害防治的36字方针,即"地面普查先行、井下勘查跟进、评价评估及时、综合治理减灾、监测监控到位、安全措施保障"。
Based on the analysis of goaf disaster accidents and main types,the goaf disaster characteristics are analyzed,the control countermeasures and suggestions are proposed. The results show that the goaf disasters are divided into four types according to the disaster forms in resources integration coal mines,that is,the abandoned old goaf or pit shaft permeable,goaf fire including coal combustion and gas explosion,the poisonous and harmful gas in goaf emission,the adverse abnormal geological disaster. The goaf has the characteristics of unknown distribution,different kinds of disaster types,concealment and happened suddenly,unpredictable. The control countermeasures principle are summarized and proposed,including ground survey in advance,underground detection following up,hazard assessment and evaluation in time,comprehensive control for disaster reduction,monitoring and supervisory in place,safety measures for guarantee.
