| Abstract: | In view of the geological structure and construction conditions of S1303 fully mechanized coal face in Gucheng Coal Mine,a combined support scheme of"anchor mesh+πtype beam shed+pre grouting"is proposed for large section cutting,which effectively controls the support problems during the construction of large section cutting and retaining top coal,guarantees that the cutting of S1303 fully mechanized coal face can meet the design requirements and complete the construction on time,and provides a reference for the same kind of construction. |
