Abstract: Aiming at the problem of support of goaf-side soft rock roadway in Yangmei Coal mines,this paper proposed the study on the deformation mechanism and relevant support technology of return airflow roadway at the 81003 working face in 2^# coal mine.Based on summarizing and analyzing the data of deformation monitoring and numerical simulation,paper presented that the original support method is not able to provide the surrounding rock with sufficient compressive resistance to form stable combined arch.Additionally,effective supporting range is within the loose circle of surrounding rock,which resulted in serious deformation even failure of roadway.According to the above conclusions,the method of reinforced support was proposed and verified by using numerical simulation and industrial tests.As the method was applied to the roadway,monitoring was carried out again and showed that reinforced support observably enhanced the strength and bearing capacity of surrounding rock.The roof-to-floor and rib-to-rib convergence decreased by 52.2% and 55% respectively.Therefore,reinforced support ensured the safety and efficiency of mining face operations.
