Research on Optimization Design of High Stress,Large Cross Section,and Large Lane Winding in Hudi Coal Industry
In order to solve the problem of difficult mine ventilation caused by severe deformation of the main roadway in Hudi Coal Industry,a new main roadway was designed between No.5 Hengchuan and No.10 Hengchuan,and four bypass layout schemes were designed based on the geological conditions of the mine production,including"inclined roadway+coal roadway","hidden shaft+flat roadway","hidden shaft+full coal roadway"and"hidden shaft+bottom rock roadway".By using numerical simulation methods,a comprehensive analysis was conducted on the roadway layout,capital investment,construction difficulty,etc.of the four schemes,and the optimal layout of the bypass roadway was determined as"coal roadway+coal roadway".The research results have important theoretical guidance significance for Hudi Coal Industry to choose a reasonable roadway layout and ensure mine safety.
