| Abstract: | By analyzing the support problems in gob-side entry driving in Tang＇an island face, in order to reduce the waste of resources and achieve high yield and efficiency of the mine, the reasonable size of small coal pillars in gob-side entry driving in island face of Tang＇an Coal Mine is determined, limit equilibrium theory is used for formula calculation, and similar simulation theory is used for study on the law of mine pressure of roadway, to determine the reasonable size of coal pillar and the corresponding key technology for roadway stability control. |
