Research on Plugging Technology of Old Drainage System of Tailings Pond
The plugging technology of traditional old pond drainage system pond is simple and lacks applicability.Taking a tailings pond as an example,in order to ensure the safety and economy of plugging at the same time,the combined plugging technology of rigid plugging and flexible plugging is proposed for the flood discharge culvert and culvert pipe of an old drainage system based on the principle of draining first and plugging later.Firstly,flexible sealing is used for drainage,then rigid sealing is used,and finally grouting is used for sealing.The practice results show that the combined plugging technology can solve the difficulties of plugging the culvert with water and the culvert pipe,and ensure the safe operation of the tailings pond.Most of the materials are selected from the tailings in the warehouse,which is convenient to draw materials.And the length of the sealing body is much larger than the standard value,which is safe and reliable.The re-search results can provide important technical support for the plugging of the old flood drainage system of similar mine tailings pond.
