Coal and gas outbursts are one of the most serious disasters in coal mining, and disaster prediction and prevention alarms are key technologies to prevent coal and gas outbursts. This paper summarizes the progress of research on outburst prevention alarm indicators and prevention alarm technology for mines; the mechanism of coal and gas outbursts; the relationship between the coal seam geological environment and outbursts; and the relationship between coal seam gas drainage, roadway excavation and mine working face (DEM) operations and outbursts. Prevention alarm indicators are key to effective prevention alarms. The analysis proposes that from the perspective of understanding the relevant theoretical research and the effectiveness, timeliness and comprehensiveness of the prevention alarms, there are still some deficiencies, and establishing preventive alarm indicators and preventive alarm models is difficult. Assuming the reasonable management of coal seam DEM, the coal seam geological environment is established as a secondary indicator. Production, gas drainage, ventilation, monitoring and control, auxiliary production and other systems are the third-level indicators. Catastrophic parameters such as safety distance, pre-extraction time, mining procedures and DEM replacement are used as fourth-level indicators for the outburst disaster risk assessment index system, which provides a basis for understanding mine risk decision-making and disaster prevention and alarms.

煤与瓦斯突出灾害因素及预防预警指标研究进展

煤与瓦斯突出是煤矿开采中最严重的灾害之一,灾害预测与预防报警是预防煤与瓦斯突出的关键技术。综述了矿井防突报警指标和防突报警技术研究进展;煤与瓦斯突出的机理;煤层地质环境与突出的关系;以及煤层瓦斯抽放、巷道开挖和工作面(DEM)作业与突出的关系。预防报警指标是有效预防报警的关键。分析认为,从了解相关理论研究和预防报警的有效性、及时性和全面性来看,还存在一些不足,建立预防性报警指标和预防性报警模型难度较大。在合理管理煤层DEM的前提下,建立煤层地质环境作为次要指标。生产、瓦斯抽放、通风、监控、辅助生产等系统为三级指标。突出灾害风险评估指标体系采用安全距离、预提取时间、采矿程序和DEM替换等灾难性参数作为第四级指标,为理解矿山风险决策和防灾报警提供依据。生产、瓦斯抽放、通风、监控、辅助生产等系统为三级指标。突出灾害风险评估指标体系采用安全距离、预提取时间、采矿程序和DEM替换等灾难性参数作为第四级指标,为理解矿山风险决策和防灾报警提供依据。生产、瓦斯抽放、通风、监控、辅助生产等系统为三级指标。突出灾害风险评估指标体系采用安全距离、预提取时间、采矿程序和DEM替换等灾难性参数作为第四级指标,为理解矿山风险决策和防灾报警提供依据。
