针对某矿回采巷道的底鼓严重问题,基于巷道底鼓变形破坏机理,据地质资料及巷道底鼓特性,采用相似模拟实验,分析了巷道围岩受力和围岩变形破坏特征,得出巷道属剪切错动型底鼓,提出打底锚杆加固底板的方案,并经数值模拟验证其方案。
針對某礦迴採巷道的底鼓嚴重問題,基于巷道底鼓變形破壞機理,據地質資料及巷道底鼓特性,採用相似模擬實驗,分析瞭巷道圍巖受力和圍巖變形破壞特徵,得齣巷道屬剪切錯動型底鼓,提齣打底錨桿加固底闆的方案,併經數值模擬驗證其方案。

According to severe floor heave deformation in mining roadways, based on the floor heave deformation mechanism, geological data, and floor heave features, the paper used analogous simulation experiment to analyze the stress and deformation features of surrounding rocks and to conclude shear staggered floor in the roadways. A floor reinforcement plan with render bolt was proposed and was verified by numerical simulation.
