According to the roadway small pillar core exploration through seepage bed, fissures, the comprehensive analysis of water quality tests worn roadway lithology and hydrogeological data section of the riverbed, roadway flood control program and supporting method were settled,  which proved that the right support parameters, reasonable construction technology organization, the use of advanced equipment grouting and grouting technology could achieve economical, safe and reliable, technically feasible aim. The technology provided a theoretical basis and practical experience for supporting technology solutions to the water at close range and loose rock roadway under construction and advanced grouting and water control support parameters .
