Abstract: The coal-rock correlation runs through the whole process of the coal geological exploration and the mine production stage. In view of the difficult problems of the coal-rock correlation in the mine production stage, such as short distance, multi-coal seams and complex structure, taking Huoshaopu Coal Mine in Panxian Coalfield of Guizhou Province as the research object, through the analysis of the geological exploration data, combined with the surface gas investigation boreholes, the underground geological survey, the gas parameter test, the marker layer suitable for the mine production stage was extracted from the coal-rock correlation marker layers established during the geological exploration stage. Combined with the data of macro and micro coal petrography, coal quality test, rock mechanics of coal roof and floor, optical characteristics of coal seams and other data exposed in shafts, roadways, two gate roads of the mined working face, open-off cuts during mine production stage, the coal-rock correlation marker based on the mining technical conditions during the production was extracted. Integrated with the geological exploration stage and the mine production stage, the standard system for the coal-rock correlation of the production stage was reconstructed. The research indicated that the coal-rock correlation marker layers established during the geological exploration stage lost basically their guiding significance in the lithological association, geophysical logs, high level marking layers and palaeobios fossil layers, but the coal seam structure, the false roof or the palaeobios fossil layer of low level direct roof, the lithological marker layers had still the guiding significance, could guide the production practices. Great amount of data about the stratum dip, the macro/micro coal petrographical component characteristics, the lithology of partings during the mine production stage, particularly the optical features such as the visible light and the thermal infrared, the parameters such as the gas content of coal seams, the pressure, the rock mechanics of roof and floor are the good marker layers for coal-rock correlation. The established technical system for the comprehensive coal-rock correlation can effectively guide the efficient tunneling of roadway, fast extraction of working face, and identify the development features of faults. The research results can not only guide the production in underground mines, but also provide the basic geological data for the intelligentized mining in underground mines in areas with complicated structures and the geological guarantee technologies for the safe, efficient and intelligentized mining in underground mining faces.
