摘　　要：根据某矿山软弱地层的实际情况,结合生产需要,通过对软岩巷道破坏机理以及复合支护原理的分析,提出了一种基于化学注浆的复合支护形式。在对巷道断面及支护参数进行科学选型和设计的基础上,经实际施工检验,取得良好的效果,单条进路多采出矿量3.15万t,给矿山带来了显著的经济效益。According to the condition of the weak stratum in a mine and combining with the production requirement, a composite support form based on chemical grouting was put forward through the analysis of the failure mechanism of the soft rock tunnel and the principle of composite support. On the basis of scientific selection and design of the tunnel section and support parameters, through the actual construction test, good results had been achieved. The mining production was increased by 31500 tons in single drift, and significant economic benefits were brought to the mine.
