摘　　要：随着煤矿巷道快速掘进技术的发展,常规超前物探方法虽然能够探测矿井地质情况,但由于探测距离较短、精度有限、数据单一、受地质条件和环境影响较大,难以做出煤矿井下复杂地质情况的宏观探测。针对察哈素煤矿开采工作面煤层厚度大、埋深浅等特点,采用YZD12矿用多参数可视化测量仪可直接获取钻孔轨迹、视频、深度和自然伽马等多元探测数据,并进行结构化数据融合分析,以解决单元数据分析引起的结果单一问题,提高隐伏地质异常区探查和识别的准确性,有效反映附近落差较小的断层等构造,实现钻孔轨迹附近地质异常区的精细探查,为煤矿安全开采提供有力证据。With the development of rapid tunneling technology in coal mine,although conventional advanced physical exploration methods can detect the geological situation of mines,it is difficult to make a macro detection of the complex geological situation of coal mine due to the shorter detection distance,limited accuracy,single data and greater influence of geological conditions and environment.Aiming at the characteristics of Chahasu coal mine,such as large thickness of coal seams and shallow burial depth in the mining face,the YZD12 mining multi-parameter visualization measuring instrument can be used to directly obtain multivariate detection data such as drill trajectory,video,depth and natural gamma,and carry out the structured data fusion analysis,in order to solve the problem of single result caused by the unit data analysis,to improve the accuracy of the hidden geological anomaly area detection and identification,and to effectively reflect the faults and other structures in the vicinity with a small drop,which realizes the fine exploration of geological anomalies in the vicinity of the drilling trajectory,and provides powerful evidence for the safe mining of coal mine.
