摘要
以21采区运输巷围岩控制为研究背景,提出通过采用强化支护、注浆以及底板支护等方式控制采动影响巷道围岩变形,并进行现场应用。现场应用后,巷道未有底鼓发生,同时巷帮、顶板变形量分别控制在223 mm、108 mm以内,围岩控制效果显著。研究成果可为其他矿井采动影响巷道围岩控制提供参考。
Based on the research background of surrounding rock control of transportation roadway in No.21 mining area,it is proposed to control the surrounding rock deformation of roadway affected by mining through strengthening support,grouting and floor support,and the field application is carried out.After field application,there is no floor heave in the roadway,and the deformation of roadway side and roof are controlled within 223 mm and 108 mm respectively,so the surrounding rock control effect is remarkable.The research results can provide reference for the surrounding rock control of roadway affected by mining in other mines.
