Stability Analysis of Surrounding Rock of Gob-side Roadway with Hard Coal Seam Roof
With the continuous improvement of mining level,the production technology without coal pillar in gob-side roadway can be applied to mining based on thin coal seam,to improve the recovery rate of mining resources and economic benefits.The stability of surrounding rock needs to be further improved in the gob-side roadway operation of a coal mine.Therefore,after summarizing the mining status of 8#coal seam in the case coal mine,the implementation conditions and application simulation of the gob-side roadway retaining technology were proposed.In the further study,starting from the support design,one of the feasible conditions of technical application,the stability control scheme of roadway surrounding rock was proposed.After monitoring,the stability of surrounding rock was good,which can meet the needs of safe mining.
