Background
The filling mining method belongs to the field of manual support mining method. In the chamber or block, as the stope face advances, fill material is fed into the goaf for ground pressure management, control of surrounding rock caving and surface movement, and stoping on or under the protection of the formed fill. The filling mining method has the advantages of high recovery rate, safe operation, surface and ground protection and the like, and is widely applied to underground mines.
The common filling aggregate used in metal mines is tailings (or tailings, including graded tailings and full tailings). The main filling process flow is that tailings with low mass concentration (generally 10-20% and 40-45% when passing through a high-efficiency thickener) from a factory are pumped to a thickener of a filling preparation station, flocculated and concentrated to high concentration (about 60-70%), then discharged into a stirring system, mixed and stirred with a cementing material (the cementing material can not be added during non-cemented filling) to form satisfactory filling slurry, and the required filling slurry flows automatically or is pumped to a place to be filled through a drilling hole and an underground filling pipeline.
The modern high-efficiency thickener mainly promotes materials to be rapidly settled and concentrated by adding a flocculating agent, and a feeding device in the thickener plays a role in mixing the flocculating agent and dispersing ore pulp and is considered as a key technology of the thickener. The conventional feeding device is a cylinder extending into the middle lower part of the thickener, and the ore pulp is radially fed into the cylinder and flows into a settling zone or a clarifying zone of the thickener through a discharge pipe in an unordered manner.
In the long-term practice process, the following problems are generally found in the feeding device of the existing high-efficiency thickener:
