Method for stoping mountainside type tailings pond

Abstract

The invention discloses a dry stoping method for a mountainside type tailing pond. The dry stoping method specifically comprises the steps that stoping of the whole tailing pond is completed through exploration of the tailing pond, stoping area division and parameter determination, transportation road laying, layered and zoned stoping in a reverse excavation mode and removal of drainage facilities and a dam body. According to the method, the crawler excavator is used for stoping tailings and loading, the open drain is excavated in the stoping zone for dewatering and drainage, and the dewatering and drainage safety and timeliness can be guaranteed; iron plates are laid on transportation roads in the warehouse according to the tailing strength for vehicle passing; according to the method, the work amount can be directly used as the recovery amount, input facilities and equipment are simple, the recovery speed of the tailings pond is increased, the recovery period is shortened, and the problem that effective working time of traditional dry recovery is short is solved. The air-drying speed of the tailings in the tailings pond is accelerated, so that the recovery work of the tailings in the tailings pond is quickly and efficiently completed on a large scale.

Description

technical field [0001] The invention belongs to the technical field of tailings mining, and in particular relates to a tailings dry-type mining method based on "drainage well + culvert pipe" drainage in a mountain-side tailings pond. Background technique [0002] During the development and utilization of mineral resources, a large number of tailings pools are produced, and considerable resources are stored in the tailings. However, the construction and maintenance of tailings dams are expensive, which has brought safety, environmental and economic impacts on mining development. And problems, especially some "overhead libraries" are the top priority of security management. [0003] Relevant national departments issued an action plan for in-depth tailings comprehensive treatment, which proposed "strengthening the research and development of tailings comprehensive utilization technologies, encouraging and supporting the research and development of a number of common key technol...

AI Technical Summary

Problems solved by technology

In this method, labor and equipment investment are significantly larger, equipment maintenance costs, and water resource costs are also relatively large. The tailings are reprocessed to increase the recovery period, thereby greatly increasing the recovery cost.

The method of stacker reclaimer + moving belt, the labor input and equipment maintenance costs are relatively large, the recovery is not flexible enough, and it is not ideal for drainage and drainage
