Abstract With the large-scale exploitation performance and deep mining，the support problems of special soft rock roadways under high stress become increasingly serious. Based on the analysis of present supporting situation for special soft rock roadways under high stress，the bolting and grouting support systems to solve supporting problems for special soft rock roadways under high stress are discussed. Experiments in the mine indicate that bolting and grouting supports can keep the stability of special soft rock roadways under high stress，and construction velocity is increased and the supporting cost can be reduced. Therefore，it shows that the bolting and grouting support systems have a brilliant prospect in practice.
