松散、破碎岩层巷道支护技术探讨

摘要

Rib spalling ,roof falling and collapse often occurring ,roadway excavation and support are very diffi-cult while constructing roadway in loose and broken strata .So normal construction and support method can't a-chieve the purpose of rapid excavation and safe construction .Aiming at the characteristics of loose and broken strata in our colliery ,surrounding support has been improved and roadway deformation has been controlled by improving construction technology and adopting advanced support technology , which achieved good support effect .%在松散、破碎岩层中施工巷道，巷道的掘进和支护都极其困难，动辄片帮、冒顶、垮塌，采用常规的施工方法和支护形式无法达到快速掘进和确保施工安全的目的。针对安宏矿松散、破碎岩层巷道的特点，通过改进施工工艺和采取超前支护技术，提高了对围岩支护的及时性、控制了巷道的变形，取得了良好的支护效果。
