Advanced support design of No.2 shaft without support and anchor cable reinforcement in Sihe Coal Mine
In view of the difficult problem in the support of mining roadway in the 153 Pan Area of No.2 Shaft in Sihe Coal Mine,the best supporting scheme was determined by comparing different support parameters by means of theoretical analysis,numerical simulation and analysis of measured data.The support scheme can effectively control the deformation of roadway surrounding rock,im-prove the roadway driving speed while ensuring the stability of roadway surrounding rock,and can provide a reference for the mining roadway supporting design under similar geological conditions.
