Abstract
Based on voussoir beam structure theory of the overlying strata, deformation mechanism of surrounding rock of gob-side entry at isolated island coal face was analyzed, principles for deformation controlling of surrounding rock were established. According to engineering geological conditions in return airway of 1251(3)Pans an colliery, and distribution of advance abutment pressure, roadways supporting scheme during the tunneling and zoning advance reinforcement plans for roadways before mining. Field practice shows that supporting scheme is feasible for stability of surrounding rock.
