Abstract: Songshan Coal Mine is affected by the high stress of the three soft coal seams under the sliding structure, the roadway
deformation speed is fast. The coal mining face adopts segmented arrangement, the amount of excavation engineering in the
mining roadway is large, the deformation is fast, the roadway maintenance project is large, and the mining and excavation are out
of balance, which seriously restricts the sustainable development of the mine. Through the research of support technology, the
problem of supporting the coal roadway of three soft coal seams was solved, and the optimization design practice of the working
face with large mining length was carried out, and the intensive and efficient production of one main shaft and one coal mining
face was realized, and the tense situation of mine replacement was alleviated.

Key words: three soft coal seams; roadway layout; optimization design; equipment selection
