Mobile filling method for managing underground gobs

Abstract

The invention discloses a mobile filling method for managing underground gobs, which is used for filling and managing the underground gobs. Components of a mobile filling station include a water supply pond, a water supply adjusting valve, a water outlet control valve, a material supply device, a stirring pond, a concentration monitoring instrument, a flow monitoring instrument, a discharging pipeline, support columns, detachable feet, a water supply pump and a water supply pipe which are assembled in a field to form the mobile filling station. The filling method for managing the underground gobs includes assembling the mobile filling station; determining the volume of the stirring pond; feeding materials in the field; and filling the materials continuously. The mobile filling method can be flexibly applied to managing small and medium-sized gobs of metallurgical, nonferrous, gold, chemical and coal mines and the like. A fixed filling station which is constructed in the small and medium-sized mines at high cost is omitted, investment of the mines is reduced, underground filling is realized more easily, potential safety hazards caused by mining are reduced, the station can be used by multiple mines, investment and mining cost of the mines are reduced, and the gobs of the mines are managed simply and practically.

Description

technical field [0001] The invention relates to a movable filling method for underground goaf management, in particular to a construction method of a simple movable filling station for underground goaf filling management, which can be used in metallurgy, nonferrous metals, gold, chemical industry, Flexible application in the management of coal and other underground empty areas. Background technique [0002] With the overall development of my country's infrastructure and national economy, the national economy's demand for mineral resources is increasing day by day. In recent years, the consumption of mineral resources has increased rapidly. A large number of residual empty areas, accounting for more than 60% of domestic production, are all mined by small and medium-sized mining enterprises, and small and medium-sized mining enterprises have low mining technology and simple equipment, and generally adopt the open-field mining method. Therefore, A large number of underground min...

AI Technical Summary

Problems solved by technology

[0005] For the underground goaf, especially the possible damage to the surface caused by the mined-out area formed after the mining of small and medium-sized mines, filling treatment is generally required, and the construction of fixed filling stations generally has a long construction period and a large fixed investment, which is difficult for small and medium-sized mines. The purpose of the present invention is to provide a mobile filling method for underground goaf management in mines, which uses a mobile filling station for goaf filling management, which can not only serve the formed goaf (group) governance, and can timely fill the single empty area formed during the production of small and medium-sized mines to avoid related hazards caused by the existence of the empty area for too long.
