基于多源数据融合的煤矿顶板灾害预警模型研究

Early warning model for roof disaster in coal mines based on multi-source data fusion

  • 摘要:
    目的 随着我国浅部煤炭资源的日益耗竭,深部开采已是大势所趋,复杂的深部开采因素导致了矿井重大灾害的频发,煤矿顶板灾害事故的发生频率和造成的死亡人数一直居高不下,成为煤矿安全生产面临的主要挑战。
    方法 为解决该问题,以下峪口煤矿为研究案例,深入分析了22306工作面支架工作阻力、锚杆锚索应力、巷道顶板离层等监测指标变化规律,得到了指标变化与灾害发生之间的关联特征,确定了科学合理的顶板灾害预警指标体系。针对当前煤矿顶板预测预警技术存在的可靠性低、准确性差以及智能化水平不足的问题,提出了一种基于多源数据融合的煤矿顶板灾害预警模型。
    结果及结论 该模型通过动态调整预警阈值,有效解决了传统固定阈值预警系统在复杂采矿环境中适应性不足的问题。利用该模型对现场实际监测数据进行了顶板灾害风险判识,验证结果表明,该模型对顶板灾害风险的预警准确率达到98.8%。

     

    Abstract: With the gradual depletion of shallow coal resources in China, deep mining has become an inevitable trend. The complex factors associated with deep mining have led to frequent occurrences of major mine disasters. Roof disasters, in particular, remain a critical challenge in coal mine safety due to their high frequency and severe1 fatality rates. Taking the Xiayukou Coal Mine as a case study, this paper analyzes the variation patterns of monitoring indicators such as support resistance in the 22306 working face, bolt and cable stress, and roof separation in roadways. The study identifies the correlation between these indicators and disaster occurrences, establishing a scientifically sound early warning index system for roof disasters. To address the current limitations in roof disaster prediction, such as low reliability, poor accuracy, and insufficient intelligence, a multi-source data fusion-based roof disaster early warning model is proposed. By dynamically adjusting warning thresholds, this model effectively resolves the adaptability issues of traditional fixed-threshold warning systems in complex mining environments. The model was applied to real-time monitoring data for roof disaster risk assessment, and validation results demonstrate an early warning accuracy rate of 98.8%.
