为了弥补现有传统接触式煤与瓦斯突出预测方法本身存在的局限性,利用瓦斯涌出动态特征进行煤与瓦斯突出预警,确定了新元矿瓦斯涌出动态特征突出预警指标体系及预警模型,构建了适用于新元矿基于瓦斯涌出动态特征的煤与瓦斯突出预警系统。经过现场应用验证:系统能够实现新元矿工作面突出危险的实时、动态预警,预警准确率达79%,实现了新元矿工作面煤与瓦斯突出灾害实时监测、在线分析、智能预警,促进了新元矿的安全生产。 In order to make up for the existing limitations of the traditional methods of predicting coal and gas outburst, the dynamic characteristics of gas emission are used to make early warning of coal and gas outburst, and the indicator system and early warning model of gas outburst dynamic characteristics are determined. A warning system for coal and gas outburst based on the dynamic characteristics of gas emission in Xinyuan Mine was constructed. After field application verification, the system can realize the real-time and dynamic warning of the outstanding danger of the face of Xinyuan Mine and the pre-warning accuracy rate reaches 79%, realizing the real-time monitoring of coal and gas outburst disasters in XinYuan mine face, on-line analysis, intelligent warning and promotion The safety of the new yuan mine production.
