The invention discloses a coal mining roadway. The coal mining roadway comprises a working surface, a ventilation roadway and a transportation roadway, wherein the ventilation roadway is arranged on a seam floor of a coal seam, and the transportation roadway is arranged between a coal seam roof and the seam floor. The working surface comprises a shelving working surface section, a transition circular-arc working surface section and an inclined working surface section, wherein the working surface is arranged in an inclined mode in the longitudinal direction, the shelving working surface section and the inclined working surface section are smoothly connected together through the transition circular-arc working surface section, the shelving working surface section is arranged on the lower oblique portion of the transition circular-arc working surface section, and is communicated with the transportation roadway, the inclined working surface section is arranged on the seam floor, is arranged on the upper oblique portion of the transition circular-arc working surface section, and is communicated with the ventilation roadway, a shelving included angle alpha is formed between the shelving working surface section and the horizontal plane, an inclined included angle beta is formed between the inclined working surface section and the horizontal plane, and the shelving included angle alpha is smaller than the inclined included angle beta. The coal mining roadway can improve the stress condition of an end support and the stress condition of a crab bearer of a large-dip-angle fully mechanized caving face, has control over downward sliding of the end support and the crab bearer of the large-dip-angle fully mechanized caving face, and is high in coal mining efficiency.
