高应力软岩巷道联合支护

With the increasing depth of coalmining, underground roadways will be a higher environment of geo-stress, especially in the areas where there have happened intense activities of geological structure. The shoring results for coalmine under the soft rock conditions were not perfect. Researching of scientific supporting fashions of soft rock roadways in high geo-stress environment is the key of ensuring coalmining deeply in Coal Mine. Therefore, basic concept of high geo-stress soft rock and its forming conditions have been discussed, basing on mastery of deformation characters and supporting principle of high geo-stress soft rock roadways, three different supporting fashions have also been researched and executed with taking high geo-stress soft rock roadways' supporting of Shanxi Mining Area as objects. The results indicate that rigid ga Pflexible layer supporting fashion is the best one which can fit effectively high geo-stress soft rock condition.
