Abstract：In order to improve the control effect of mine pressure in the isolated working face,taking the 14203-1 working face of the mine as the research object,aiming at the instability of the surround-ing rock structure during the mining of the isolated island working face,the appearance law of the mine pressure was analyzed by means of on-site monitoring,and the reasonable stage of roadway ex-cavation was determined,and the width of the small coal pillar of the 14203-1 belt along the groove was determined to be 7.0 m based on theoretical calculation and numerical simulation,and the anchor rod+anchor cable+W/JW high-strength steel belt+combined anchor cable+metal mesh combined sup-port process,practice shows that the technology can effectively improve the recovery rate of coal re-sources,ensure the stability of the surrounding rock,during the mining of the 14203-1 working face,the deformation of the surrounding rock of the roadway is within the controllable range,and the safe mining of the small coal pillar working face of the isolated island is realized.
