注浆加固技术在防治巷道底鼓中的应用

摘要

The main reason of the under the condition of soft rock roadway bottom heave and a supporting failure were analyzed, through the analysis of the comprehensive factors of geological conditions, surrounding conditions, support type conditions, and the new types of support and grouting reinforcement of lfoor was put forward, which effectively solved the inlfuence factors of soft and broken surrounding rock, and water, controlled the lfoor heave of roadway, and ensured the stability of the roadway.%该文分析了在软岩条件下巷道底鼓及支护失败的主要原因，通过对地质条件、围岩状况、支护型式等条件的综合因素分析，提出了新的支护型式及注浆加固巷道底板，有效解决巷道围岩松软、破碎及水的因素影响，控制了巷道底鼓，保证了巷道稳定，提高了安全可靠性。
