摘　　要：提出了回采工作面地质模型的3层构建框架,阐述了回采工作面煤层模型的构建过程;采用综合动态解释技术对地质、钻探、物探数据进行数据融合;采用多级多属性三维动态地质模型构建技术建立回采工作面煤层模型,根据采煤机截割参数和煤层三维地质模型生成采煤机截割曲线供采煤机进行割煤作业。在试验工作面进行了应用,对巷道测量、切眼测量、钻孔伽玛、钻孔雷达探测、槽波探测数据进行综合解释,构建了工作面的三维地质模型,依据采煤机截割参数生成截割曲线并通过集控系统下发给采煤机,指导采煤机基于煤层模型进行割煤工作。This paper puts forward a three-layer construction framework of the geological model for the working face, and expounds the construction process of the coal seam model of the working face. The comprehensive dynamic interpretation technology is used for data fusion of geological, drilling and geophysical data. The multi-level and multi-attribute 3D dynamic geological model construction technology is used to establish the coal seam model of the working face. According to the cutting parameters of shearer and 3D geological model of coal seam, the cutting curve of shearer is generated to guide the coal cutting operation. It has been applied in the experimental working face. The data of roadway survey, cut-out survey, borehole gamma,borehole radar detection and trough wave detection are comprehensively interpreted. The 3D geological model of working face is constructed and distributed to the shearer through the centralized control system to guide the shearer to cut coal based on the coal seam model.
