Researchers studied how weak cohesive roofs in deep buried coal mines behave to prevent ground pressure issues and spontaneous combustion risks. They found that deep buried thick coal seams cause slow surface subsidence and short periodic weighting step distances. The average step distance is 9.9m, and the peak advance abutment pressure is measured 7-10.5m in front of the coal wall. To control mine pressure and prevent fires, it is recommended to advance at a speed of 4-5m per day.
