Description

TECHNICAL FIELD

[0001] The utility model relates to mine drainage technical field especially relates to a drainage structure based on mine ecological restoration. BACKGROUND

[0002] In the mine ecological restoration process, the water resources needed for greening irrigation, dust fall and other operations are large, and the water resources in the drainage structure can be recycled and utilized, which can effectively reduce the dependence on external water sources. A medium-sized mine may need tens of cubic meters of water for greening irrigation every day during the restoration period. If the recycled water can be utilized, the corresponding external water supply cost can be saved. In water resource shortage areas, this helps to alleviate the pressure on local water resource supply. Recycling and utilizing internal drainage resources can make the mine more self-sufficient in water resource supply and ensure the continuous development of ecological restoration work.

[0003] The applicant found through retrieval that a patent for "a drainage structure based on open-pit mine waste rock field ecological restoration" has been disclosed in China, with publication (announcement) number CN 222139925 U. The patent mainly includes a drainage channel, and an intercepting plate is arranged inside the drainage channel. The device has a simple structure and is convenient to operate, can effectively intercept sundries in the water in the drainage channel, and is convenient for cleaning the intercepted sundries. In addition, the device is equipped with a monitoring camera, so that personnel can remotely monitor the condition of the intercepting plate inside the drainage channel to make a timely response. However, although the V-shaped plate is used to clean the sundries in the water in the above-mentioned prior art, it may still contain a certain amount of pollutants, such as trace amounts of heavy metal ions and minerals. If the water is directly discharged into the surrounding water body, it may cause long-term pollution to the water ecological environment, thereby affecting the health of the surrounding river, lake and other ecological systems. Therefore, we propose a drainage structure based on mine ecological restoration. UTILITY MODEL CONTENT
