Abstract: The geological strata of the 12406 face, Bulianta mine was detected by GPR that has the advantage of a fine probing for shallow surface layers. According to the radar face, the stratification of the study area is divided into five different types. Combined the borehole data with the GPR profile, sedimentary structures along the survey line was obtained, which would be basic data for mine ecological reclamation. The detection results show that: the thickness of shallow loose layer is different sharply. The GPR wave probing is deeper in all sand layers than other loose layers. GPR detection was good in survey line 1200-1500m range sand layer deposition and the effective signal was up to 10m. The interface of coarse sand, medium sand or fine sand can be identified. The GPR detection depth is shallow in clay (sandstone weathering products) and gravel area; depth, which is corresponding with the deep of clay and gravel and shallower than 10m, some only a few tens of centimeters thick.
