摘要

由于综合机械化采煤技术不断提高及开采深度的增加,工作面内部地质异常构造制约着矿井高产高效、安全生产。因此需提前对内部地质异常构造进行精细探查、预测预报,为工作面安全回采提供指导。CT层析成像技术分辨率高且探测精度高,能够探查清楚工作面内部复杂构造的分布情况。采用CT层析成像技术对燕子山矿8208工作面进行探查分析,并进行回采验证。结果表明,CT层析成像技术对探查工作面异常构造效果较好,为工作面安全回采提供了重要保障。
        Due to the continuous improvement of comprehensive mechanized coal mining technology and the increase of mining depth,the geological anomaly structure inside the working face restricts the high-yield,high-efficiency and safe production of the mine.Therefore,it is necessary to carry out fine exploration,prediction and prediction of the internal geological anomaly structure in advance,and provide guidance for safe mining of the working face.CT tomography has high resolution and high detection accuracy,which can detect the distribution of complex structures inside the working surface.The CT tomography technology was used to probe and analyze the 8208 working face of Yanzishan Mine,and the recovery was verified.The results showed that the CT tomography technology had a good effect on the abnormal construction of the exploration face,which provided an important guarantee for the safe mining of the working face.
