Said invention concerns a type of technological field-restoring systematic device for gold-mining ship. By conversion of the gold-mining ship's gravel-, sand- and dirt-discharging systematic devices, and adding some equipment, the gold-mining ship can then, by using its own equipment, achieve the whole process of gold-mining and field-restoration in one single step. By using said systematic device to replace common bulldozer in field-restoration works, one can not only restore immediately the field's stratigraphic and geomorphic conditions, as well as the vegetation's ecological conditions, but one can also save energy, lower the cost and hence can provide remarkable economic benefits. |
