| Abstract: | In view of the difficulties in supporting large cross-section broken surrounding rock in Baozi Coal Mine,through the comparison of surrounding rock support technology,the combined support technology of "grouting + anchor cable" is put forward,and the field industrial test is carried out through roof and slope peeping and surrounding rock deformation observation.The results show that the support effect is good,which can be used as a reference for broken surrounding rock support under similar geological conditions. |
