A perception alarm method for coal mine rock burst and coal and gas outburst based on burial image features

  • 摘要: 分析了冲击地压和煤与瓦斯突出时抛出大量黑色煤岩的掩埋图像特征:监视区域内颜色及其对应图形面积变化、颜色及其对应图形数量变化、颜色及其对应图形形状变化、掩埋位置异常等。根据灾害发生时会造成监视区域内非黑色区域面积减少,且减少的速度和加速度较大的特征,提出了基于颜色及其对应图形面积变化特征的冲击地压和煤与瓦斯突出感知报警方法。根据灾害发生时会造成监视区域内非黑色区域数量减少,且减少的速度和加速度较大的特征,提出了基于颜色及其对应图形数量变化特征的冲击地压和煤与瓦斯突出感知报警方法。根据灾害发生时会造成监视区域内非黑色图形的圆形度、矩形度和面积周长比减少,且减少的速度和加速度较大的特征,提出了基于颜色及其对应图形形状变化特征的冲击地压和煤与瓦斯突出感知报警方法。根据灾害发生时会导致煤矿井下人员、液压支架顶部及靠近顶部等位置被煤岩掩埋的特征,提出了基于掩埋位置异常特征的冲击地压和煤与瓦斯突出感知报警方法。上述基于掩埋图像特征的煤矿冲击地压和煤与瓦斯突出感知报警方法具有响应速度快、非接触、监测范围广、成本低和使用维护方便等优点。

     

    Abstract: The burial image features of a large amount of black coal rock thrown out during rock burst and coal and gas outburst are analyzed. The features include changes in the area of the monitoring area's color and corresponding graphics, changes in the number of colors and corresponding graphics, changes in the shape of colors and corresponding graphics, and anomalies in burial positions. When a disaster occurs, it will result in a reduction in the area of non-black areas within the monitoring area, with a significant reduction in speed and acceleration. Based on the above feature, a perception alarm method for rock burst and coal and gas outburst is proposed based on the features of color and its corresponding graphic area changes. When a disaster occurs, it will result in a reduction in the number of non-black areas within the monitoring area, with a significant reduction in speed and acceleration. Based on the above feature, a perception alarm method for rock burst and coal and gas outburst is proposed based on the features of colour and its correspoding graphic number changes. When a disaster occurs, it will cause a decrease in the circularity, rectangularity, and area-to-perimeter ratio of non-black graphics within the monitoring area, with a significant reduction in speed and acceleration. Based on the above feature, a perception alarm method for rock burst and coal and gas outburst is proposed based on the features of color and its corresponding graphic shape changes. When a disaster occurs, it can lead to underground coal mine personnel, hydraulic support at the top and near the top being buried by coal and rock. Based on the above feature, a perception alarm method for rock burst and coal and gas outburst is proposed based on the features of abnormal burial position. The above perception alarm method for rock burst and coal and gas outburst based on burial image features has the advantages of fast response speed, non-contact, wide monitoring range, low cost, and convenient use and maintenance.
