应力显现条件下掘进支护方式的研究与应用

Research and application of tunneling support under the condition of stress appearance

文章介绍了兴隆庄煤矿10309运顺综掘工作面,在特殊地质条件施工期间,出现应力集中显现情况,通过对地质条件、顶板变化和支护方式的分析、研究与总结,不断改进优化支护方式,顺利完成了对应力集中显现区域的加固和后续巷道的掘进支护工作。为今后矿井在类似地质条件下掘进施工积累了宝贵的经验,具有极强的借鉴意义。

The paper introduces the stress concentration in the 10309 drivage face of Xinglongzhuang coal mine during the construction of special geological conditions.Through the analysis,research and summary of geological conditions,roof changes and support methods,continuous improvement and optimization of support methods,the stress concentration of the region to complete the reinforcement and follow-up roadway excavation and support work.It has accumulated the valuable experience for the mine excavation construction under the similar geological condition in the future,and has the extremely strong reference significance.
