Key Technologies of Active Advance Support for Mining Roadways in Fully-mechanized Mining Faces
In order to solve the problem of the support stability of the advance section in the fully-mechanized mining face of Huipodi Coal Mine,the key technology of active advance support was proposed.The grouting combined with anchor cable support scheme achieved an organic combination of slurry and anchor cable,effectively controlling the deformation of the roof and two sides,and the anchor cable provided axial force to ensure the overall stability of the surrounding rock,providing safety guarantees for the fully-mechanized mining face.
