煤与瓦斯共生灾害现状研究

为了分析煤与瓦斯共生灾害研究现状，介绍了共生灾害特性及耦合关系的研究进展，揭示了共生灾害机理及防治方法，根据目前现状提出了研究存在的不足及展望。研究结果表明，共生灾害多物理场耦合关系复杂、灾害趋势明显，但目前共生灾害研究存在实验研究针对性不强、未考虑全面漏风场优化机制、缺少共生灾害风险识别模型及预警机制、防控体系较弱等弊端。在研究中应加强实验的侧重性，在工程实践中进一步优化漏风场，并构建瓦斯与煤自燃共生灾害风险辨识与风险判别指标体系，建立共生灾害风险识别模型及预警机制，降低共生灾害频率及后果。研究可为共生灾害防治提供理论指导。

Research on current situation of coal and gas symbiosis disaster

In order to analyze the research status of coal and gas symbiosis disasters，the research progress of symbiosis disaster characteristics and coupling relations were analyzed，the mechanism and prevention methods of symbiosis disasters were revealed，and the research deficiencies and prospects were put forward based on the current status.The results showed that the multi-physical field coupling relationship of symbiotic disasters was complex and the disaster trend was obvious.However，the current research on symbiotic disasters had experimental research that was not very specific，did not consider the overall wind leakage field optimization mechanism，and lacks symbiotic disaster risk identification models，early warning mechanisms，prevention and control systems，weakness and other disadvantages.The emphasis of the experiment should be strengthened in the research，in engineering practice，the wind leakage field was further optimized，and the risk identification and risk identification index system for the symbiosis of gas and coal spontaneous combustion was established.Establish a symbiotic disaster risk identification model and early warning mechanism to reduced the frequency and consequences of symbiotic disasters.It could provide theoretical guidance for symbiotic disaster prevention.
