摘要
软岩巷道稳定性一直是长期困扰地下采矿工程发展的关键技术问题之一 ,以Hoek -Brown准则作为破裂区岩体的强度准则 ,从理论上对软岩巷道的合理支护强度进行了分析研究 ,并推出了相应的计算公式。
The stability of the surrounding rock of soft strata roadway has long been one of the key technical problems puzzling the underground mining engineering development.With Hoek-Brown criterion as the fractured zone rock's strength criterion,theoretical study on the reasonable support strength is made and the related calculation formula deduced.
