Abstract: This paper introduces the new dewatering cage's structure and filtering materials in Yingezhuang Gold Ore，and analyzes and calculates the pressure-bearing，filtering and tailings deposition of the dewatering cage.The field test shows that the filtered water from the dewatering cage contains less tailings with fine clay content of ≤ 0.5% after sampling and drying.The new dewatering cage has a good filtering effect under continuous filling conditions.

Key words: Dewatering cage, Filtering materials, Tailings deposition, Continuous filling
