厚煤层综放工作面注浆加固治理技术应用与分析

Application and Analysis of Grouting Reinforcement of Thick Coal Seam

为解决综放工作面动压巷道及三角煤破坏变形难题,通过超强矿用无机加固材料注浆加固三角煤,保持围岩的完整性,有效地提高围岩的整体强度、改善支护体的支护特性,降低巷道变形量,实现了工作面的安全高效生产。

In order to solve the problem of dynamic pressure roadway and triangle coal on the working surface,the triangular coal is reinforced by inorganic reinforcement materials to maintain the integrity of the surrounding rock,effectively improve the overall strength,improve the supporting characteristics of the supports,reduce the deformation of the roadway,and realize the safe and efficient production of the working surface.
