| Abstract: | In order to improve the stability of the surrounding rock and ensure the safety and rapid installation of the working face equipment,the hydraulic hole making and pressure relief technology is adopted for the 8507 working face roof,the combined support measures of"staggered superposition JW type steel belt+directional anchor cable hanging shed+erecting"well"shaped wood crib"are proposed for the roof,and the directional staggered anchor bolt support is adopted for the roadway side,with remarkable results. |
