| Abstract: | The paper introduce the Pressure observation around 44305 coal face in Yu Jia Liang Mine. We Face with mine pressure behavior characteristic and reference to step with pressure from the theoretical calculation. We identified the face cycle steps with pressure. We mastered the mining face during the operational status of stent. All of this provides a basis for the management of coal seam roof. |
