随着煤矿开采深度的不断增加,井下煤矿巷道将处于更高的地应力环境中,尤其在地质构造活动强烈的地区,井下巷道支护及稳定性更加难以保证。研究高地应力软岩环境下巷道科学的支护方式是保证煤矿采掘深部煤层的关键。就高应力软岩的基本概念及形成条件进行了讨论,在掌握高应力软岩巷道的变形特征和支护原理的基础上,以芙蓉矿区白皎煤矿井下高应力软岩巷道支护为对象,对3种不同的支护方式进行了研究与实践,结果表明预留刚隙柔层支护方式为最佳的适合高应力软岩条件下的巷道支护方式。
With the increasing depth of coal mining, underground roadways will be a higher environment of geo-stress, especially in the areas where there have happened intense activities of geological structure. Researching of scientific supporting fashions of soft rock roadways in high geo-stress environment is the key of ensuring coal mining 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 Baijiao Coal Mine in Furong 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.
