The study looked at how stress is distributed in coal pillars of different widths in mining short-range coal seams. Using a computer program, researchers found that stress concentration in coal pillars affects floor stress more than roof stress. They also discovered that as the width of the coal seam increases, the maximum stress in the coal seam first rises and then falls. By analyzing stress diffusion angles, they designed roadways in low-stress areas to minimize deformation and ensure good support during mining.
