Abstract: This paper probed into the roadway excavation support in the area affected by the collapse column stress. Combined
with the actual engineering, based on the analysis of the shortage of the original support method, it summarized the failure
mechanism of the roadway in the area affected by the collapse column stress, and then carried out in-depth research on the
optimization of the roadway support method. The results show that the optimized roadway support method ensures the safety and
stability of driving through the stress affected area of collapse column, and improves the comprehensive benefits of the mine.

Key words: mine; collapse column; areas affected by the stress; roadway excavation; excavation support
