Research on Surrounding Rock Reinforcement Technology for Mining Roadway in Island Working Face
In response to the problem of large deformation of the surrounding rock in the 15307 working face mining roadway,shallow and deep hole grouting was carried out on the roadway side and roof to improve the overall stability and strength of the rock mass,creating good conditions for controlling the deformation of the surrounding rock in the subsequent roadway.By using anchor cables to reinforce the roadway and roof,and anchoring the entire length of the anchor cables,the coupling effect between the support system and the surrounding rock can be improved.After on-site application,the convergence values of the top and bottom plates,as well as the two sides of the mining roadway in the 15307 working face were 258 mm and 117 mm,respectively,during the advancement of the mining face.This overall reduced the deformation of the surrounding rock,indicating that the on-site use of the roadway surrounding rock reinforcement technology has achieved good results.
