摘　　要：传统的煤矿底板水害预测方法主要依赖于物理观测和经验分析,为了提高煤矿底板水害预测精度,有效地预测煤矿底板水害的发生,保障煤炭生产和矿工安全,展开基于微震监测技术的煤矿底板水害自动预测方法研究。通过从微震数据中提取视体积与能量指数特征参数,能够更有效地反映底板的应力状态和破裂模式。这些特征参数能够在较大程度上体现底板水害发生的趋势,为后续建立预测模型提供重要的依据。基于采集的微震数据和提取的特征参数,结合底板水害的历史数据和相关环境因素,建立煤矿底板水害风险的预测模型。该模型能够根据不同的底板状态进行动态预测,提高预测的精度和准确性。实验结果表明,该方法应用后,煤矿底板水害自动预测的平均绝对误差最大不超过0.94%,表明预测值与实际值更加接近,预测精度得到了显著提升。这意味着该方法具有较高的预测准确性,可以更好地保障煤炭生产和矿工的安全。The traditional coal floor water damage prediction method mainly relies on physical observation and empirical analysis.In order to improve the prediction accuracy of coal floor water damage,effectively predict the occurrence of coal floor water damage,and ensure coal production and miners'safety,the automatic prediction method of coal floor water damage based on microseismic monitoring technology is studied.By extracting the characteristic parameters of apparent volume and energy index from the microseismic data,the stress state and fracture mode of the floor can be reflected more effectively.These characteristic parameters can reflect the trend of floor water damage to a large extent,and provide an important basis for the subsequent establishment of prediction models.Based on the collected microseismic data and extracted characteristic parameters,combined with the historical data of floor water damage and related environmental factors,the prediction model of coal mine floor water damage risk is established.The model can make dynamic prediction according to different states of the bottom plate,which improves the precision and accuracy of prediction.The experimental results show that the maximum average absolute error of automatic prediction of water damage in coal mine floor is less than 0.94%,which indicates that the predicted value is closer to the actual value,and the prediction accuracy has been significantly improved.This means that the method has high prediction accuracy and can better guarantee the safety of coal production and miners.
