| Abstract: | The strata in the driving area of the 22212 haulage roadway are broken and it is dif ficult to control the surrounding rock.In order to ensure the safe use of the roadway,the comprehensive reinforcement scheme of“grouting reinforcement+grouting anchor cable support”is proposed,and the reasonable grouting and anchor cable support parameters are designed.Through grouting and anchor mesh cable support,the bearing capacity of surrounding rock is improved,and good application effect is achieved on site. |
