摘　　要：在地下矿高大硐室施工过程中,由于硐室断面大、变化多,长度则比较短,而且地质条件复杂,大型施工机械难于进入工作面施工,所以在高大硐室具体施工方法的选择上比较。依据硐室的形状、规格和结构差别,所穿过的岩石性质,围岩的稳定性等情况,介绍了全断面开挖法、导坑开挖法和留矿开挖法的适用条件及施工案例,从而为高大硐室的施工方法选择上提供了相关的参考。During the construction of a tall and large chamber in an underground mine,it is difficult for large construction machinery to enter the working face due to the large section and change of the chamber,the length is relatively short,and the geological conditions are complex.Therefore,it is difficult to select specific construction methods for tall and large chambers.Based on the shape,specifications and structure of the chamber,the characteristics of the rock passing through,the stability of the surrounding rock,etc.,this article introduces the applicable conditions and construction cases of the full-section excavation method and the pilot pit excavation method and retention excavation method,provide relevant references for the selection of the construction method of the tall chamber.
