摘要
结合具体工程实际,在分析巷道底鼓发生机理的基础上,运用数值模拟手段对开挖卸压槽治理底鼓的效果进行了分析,探究了不同开挖深度同底鼓量之间的关系,并最终通过实践探究了其实际应用效果。结果表明,采用开挖卸压槽的方法对底鼓进行治理的效果显著,对于提升作业安全性、降低作业成本有着积极意义。
        Combined with the actual project and based on the analysis of occurrence mechanism of floor heave in roadway, this paper analyzed the effect of excavating pressure relief groove to control floor heave by means of numerical simulation, probed into the relationship between different excavation depths and floor heave amount and finally explored its practical application effect through practice. The results show that the method of excavating pressure relief groove has a significant effect on floor heave treatment, which is of positive significance for improving operational safety and reducing operational cost.
