| Abstract: | Aiming at the problem of low driving efficiency of coal roadway in Hulusu Coal Mine,based on the control theory of roof continuous beam and high pre-tight long anchor technology,the original support scheme of roadway is improved,taking the transportation roadway of 21405 working face as the object,using single flexible large bolt support and increasing bolt row distance to 1.5 m,the average daily advance of roadway driving is 25.3 m,and the maximum daily advance is 31.5 m,which realizes the safe,efficient and fast driving of coal roadway. |
