Abstract:With mining depth increasing,the geological and mechanical conditions of roadway become more complicated compared with those in shallow roadway,if the range of fore-reinforce supporting for shallow or middle roadway is used to deep mining roadway with dynamic pressure the surrounding rock deformation of deep mining roadway will be not effectively controlled.The paper has analyzed the supporting and fore-reinforce supporting of the crossheading in a working face with a buried depth of 762 m,and the research results show that the deformation of roadway surrounding rock in roadway driving mainly is floor heave,and in mining mainly is roof subsidence,the influence range of fore support pressure of deep mining roadway effected by dynamic pressure enlarge markedly,the range of fore-reinforce supporting should is larger 5~10 m than the influence range of dynamic pressure.
