Abstract
In order to solve the problem of excessive deformation of surrounding rock of soft rock roadway under weak aqui-fer,this paper taking 51408 working face transportation roadway of Qifeng Coal Industry as an example,adopts a series of re-search methods such as theoretical analysis,numerical simulation and field measurement to explore the deformation and fail-ure mechanism of surrounding rock of roadway,and puts forward a technical scheme to control the stability of surrounding rock of this type of roadway.The contact channel between water and weak rock is blocked,and the combined support scheme of"cable net injection+deep hole grouting"is adopted.The field measurement results show that the new scheme enhances the preload force and anchorage force of the anchor cable,and strengthens the load bearing performance of the surrounding rock.According to the deformation monitoring results of the surrounding rock of the roadway,the maximum convergence of the roof and floor of the roadway is 28.0 mm,and the maximum convergence of the two sides is 52.0 mm,which can ensure the normal use of the roadway.关键词
