煤与瓦斯突出综合预警系统在严重突出矿井的建设

为了提升煤与瓦斯突出矿井防突水平和抗灾能力,以事故预警理论为指导,从瓦斯灾害防治实验室和预警平台2方面为示范矿井建设了煤与瓦斯综合预警系统。通过预警系统建设,形成了适合矿井实际特征的煤与瓦斯突出综合预警指标体系和规则库模型,从煤层及瓦斯赋存特征分析、采掘空间安全情况分析、钻孔施工效果分析、日常预测指标发展趋势、瓦斯涌出特征实时跟踪、超掘(采)动态监控等方面实现了煤与瓦斯突出灾害的在线监测、超前预警和过程化控制。现场应用表明,预警系统具有较高准确性,能捕捉分析矿井瓦斯突出灾害的潜在隐患和预兆,能为矿井防突提供决策依据和技术保障,并促进矿井的精细化、规范化管理和信息化交流。

Construction of Comprehensive Warning System for Coal and Gas Outburst in Serious Outburst Mine

In order to improve outburst prevention level and anti-disaster capacity in coal and gas outburst mine,taking the accident warning theory as the instruction,the comprehensive warning system for coal and gas outburst has been established in demonstration mine from the gas disaster prevention laboratory and warning platform.By the establishment of warning system,the coal and outburst comprehensive warning indicators and rule base models which were suitable for the actual mine characteristics were formed.The on-line monitoring,advanced warning and process control for coal and gas outburst disaster were achieved from the analysis of coal and gas occurrence features,analysis of mining space security situation,analysis of borehole construction effects,daily predictor development trend,real-time tracking on characteristics of gas emission and dynamic monitoring of over-dig and overdraft.Field application shows that the warning system has higher accuracy,and can capture the potential pitfalls and harbingers in coal and gas outburst disasters,provides basis for decision making and technical support for mine outburst prevention,and promotes meticulous,standardized management and information exchange for coal mine.
