The geological structure of Hulie’s coalfield in the Yubei mining area of Inner Mongolia is complex and the surface water system in the coal-bearing basin is developed. The Erguna river flows from the south to the north from the northwest of the exploration area. The predecessors have carried out many geological and geophysical exploration works in the study area.Based on the characteristics of the water-relationship relationship in the fault structure of this area

the transient electromagnetic method was used for exploration. The transient electromagnetic method（TEM） is sensitive to water bodies and has high resolution. It has significant advantages in the exploration of the zone

and then analyzes the anomaly in combination with the geological conditions of the zone. The low-resistance anomaly zone of the bottom rock layer of the main coal seam of the 2 coal group is divided

and the water-bearing position and range of the coal group are delineated to achieve the purpose of predicting the low-resistance water-removing zone.
