The mining area is located in the northern section of Helan Mountain, and the Ida field is a basin-facing syncline with its eastward gentle western steep rising up at the northern end. There is no large fault structure except for some gentle folds in the syncline wing. The minefield is located at the northern end of the Rujigou syncline. The east wing is relatively slow (20 °) and the west wing is steeper (30 °). The northern end of the syncline is lifted to the south and west and its dip angle changes from north to south to 12 ° ~ 8 ° ~ 5 °, axial
