Abstract
Based on the engineering background of the belt conveyance roadway in the north wing of Zhuxianzhuang Coal Mine, this paper puts forward and analyses the existing problems in the optimization of the roof roadway location in upstream mining, and studies the movement law of overlying strata under different mining heights by FLAC3D numerical analysis software. On this basis, the orthogonal test is used to analyze the optimization of different location of roadway in overlying strata, determine the weights of three factors affecting the selection of roadway location, and put forward a reasonable roadway location for belt conveyance roadway in the north wing of Zhuxianzhuang Mine. According to the occurrence and use of surrounding rock of belt conveyance roadway in North Wing of Zhuxianzhuang Mine, two schemes of zonal support are put forward. Industrial test shows that the support effect is greatly strengthened and the support condition is improved, which can be used as a reference for the location selection of coal mine roadway and surrounding rock control under similar geological conditions.
