| Abstract: | Based on the features of the serious deformation of gobside entry retaining in fully-mechanized caving face and many random variables of the mechanics parameters of the surrounding rocks,the necessity of reliability analysis on the support structure was elaborated.Furthermore,the reliability analysis model of the support structure of gob-side entry retaining in fully-mechanized caving face was established and the calculating formulas of reliability of the support structure were obtained with the engineering structure reliability theory.The result shows that the reliability of support structure of gob-side entry retaining in fully-mechanized caving face is improved by selecting rationally bolt types,increasing the thickness of bolt supporting,and improving the mechanics properties of supporting materials of anchorage and roadside packing. |

| Keywords: | gob-side entry retaining in fully-mechanized caving face support structure bolt support reliability |
