Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the following examples are given to further describe the present invention in detail.

[0026] An underground waste roadway full tailings consolidation disposal system, including: pipeline control system, slurry isolation system, drainage system and waste roadway 4;

[0027] The abandoned roadway 4 is divided into several stages in the length direction; each section has a length of 50m to 70m;

[0028] The pipeline control system includes: several feed pipes 1 , fixed brackets 8 and anchor rods 9 .

[0029] The fixed support 8 is an inverted triangle rigid metal material, which is processed according to the diameter of the feed pipe 1, and the feed pipe 1 is embedded in the fixed support 8, and the fixed support 8 is fixed on the central position of the top plate of the abandoned roadway 4 with an anchor rod 9;

[0030] The feed pipe 1 is used for transporting filling slurr...

Abstract

The invention discloses an underground abandoned roadway full tailings consolidation disposal system and method. The underground abandoned roadway full tailings consolidation disposal system comprisesa pipeline control system, a slurry isolated system and a drainage system. An abandoned roadway is divided into a plurality of stages, lower layer retaining walls are separately built at suitable positions of a first stage and a second stage, during filling, the second stage filling retaining wall is used as a first stage cutoff wall, filling pipelines are laid finally, filling slurry preparationis completed and reaches filling areas through feeding pipes, slurry waste water is discharged through a filter pipe for building the upper layer retaining wall with filling until complete blockage,at the moment, the first stage filling is completed, pipeline threads are opened, the first stage pipeline is disassembled, and receding type filling is carried out on the residual stages gradually. The underground abandoned roadway full tailings consolidation disposal system has the advantages that the defects that a traditional filling method retaining wall is unstable and complete filling cannot be carried out are overcome, and meanwhile, the advantages of economy, rapidness, continuity, safety, stability and efficiency are achieved.

Description

technical field [0001] The invention relates to the field of mining technology, in particular to a system and a method for consolidating tailings in underground abandoned tunnels. Background technique [0002] The discharge of tailings in my country is huge, except for a few tailings that are used, most of them are piled up in the surface tailings ponds. According to statistics, my country's metal mines have accumulated more than 4 billion tons of tailings pools on the ground, and the annual growth rate is 210 million tons. This not only occupies a large amount of land resources, causes environmental pollution, but also poses certain safety hazards and is extremely harmful. In actual mine production, abandoned roadways account for a large proportion of abandoned space, and the actual utilization rate is not high. If the tailings consolidation discharge can be selected in the abandoned roadway, the filling efficiency will be greatly improved, the space above the ground will ...
