Abstract

The large-section gob-side tailentry of the sublevel caving face often deforms heavily in the horizontal direction when driving and mining in deep mines, especially the side of solid coal, so it is difficult to support and needs several maintenances for the enough space. The control mechanism and technology is put forward based on the location of the main roof’s lateral fracture to decrease the large deformation. And the field test and monitoring of gob-side roadway is done in 1306 coalface in Dongtan Mine. It is proved that the tailentry's horizontal deformation is obviously reduced..
