基于机器学习的瓦斯隧道钻机行为感知和煤岩识别
Behavior Perception of Gas Tunnel Boring Machine and Identification of Coal-Rock Based on Machine Learning:Taking Zhaotong Tunnel as an Example
目的 为了解决瓦斯隧道打钻过程中煤岩界面识别问题,开发基于机器学习的钻机行为感知和煤岩识别系统。 方法 采用K均值聚类算法感知钻机运行过程中的不同状态。经过多次数据混合迭代后,煤岩识别算法的准确性得到了有效提高;在滤波方法的比较中,中值滤波效果显示出更高的识别度。和设计见煤深度对比,现场试验的4个钻孔的见煤深度分别减小了3.5%、11.6%、17.2%和9.3%,结果验证了该系统的准确性。 结果 该研究为隧道地质钻探及瓦斯治理提供了创新解决方案,同时也为复杂地质条件下的岩性识别提供了可靠参考。
Purposes In order to address the problem of coal-rock interface recognition during gas tunnel drilling, a machine learning-based drilling behavior perception and coal-rock recognition system is developed. Methods In the system, k-means clustering algorithm was employed to perceive different states during the drilling process and its effectiveness in detecting boreholes was validated. Through multiple iterations of data blending, the accuracy of the coal-rock recognition algorithm was significantly improved. In comparing different filtering methods, the median filtering method exhibited higher recognition accuracy. Additionally, the field experiments demonstrated a decrease in coal depth by 3.5%, 11.6%, 17.2%, and 9.3% for the four drilled holes, respectively, compared with those of the design depth. Results These results validate the accuracy of the system and provide an innovative solution for tunnel geological drilling and gas management, which provides a reliable reference for rock type identification with complex geological conditions.
