Problems solved by technology

However, due to the high concentration of filling slurry in paste filling, its transportation resistance in the pipeline is large, which leads to pipeline blockage during pipeline transportation. Once the pipeline is blocked, it needs to be dredged in a short time, otherwise the filling material After the slurry is solidified, the pipeline will be scrapped and cannot be used. However, the paste filling slurry has a high concentration and high viscosity. After the pipe is blocked, it is difficult to quickly dre

Example Embodiment

[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0045] On the one hand, if Figure 1 to Figure 4 As shown, an embodiment of the present invention provides a method for processing a paste filling pipeline, the method comprising:

[0046] The blocked filling pipes are dredged by high pressure air;

[0047] Drain and clean the filling pipes with water and discharge the water into the sedimentation tank;

[0048] The filling pipeline after filling is cleaned by high pressure air.

[0049] 101. Unblock the blocked filling pipe through high-pressure air.

[0050] like figure 2 As shown, multiple emergency pipelines and high-pressure pipelines are pre-installed, and multiple emergency pipelines are arranged on the filling pipeline at intervals, that is, a filling pipeline is set between two emergency pipelines, and multiple emergency pipelines are installed at intervals on the filling pipelin...

Abstract

The invention discloses a treatment method and device for a paste filling pipeline, relates to the technical field of mining area backfilling, and mainly aims to provide the treatment method for the paste filling pipeline. The method can quickly block and dredge the filling pipeline and can prevent water for drainage and cleaning from entering a stope in the paste filling process. According to the main technical scheme, the treatment method for the paste filling pipeline comprises the steps: dredging the blocked filling pipeline through high-pressure air; conducting drainage and cleaning on the filling pipeline through water, and discharging the water into the sedimentation tank; and cleaning the filling pipeline after filling through high-pressure air. The method is mainly used for mining area backfilling.

Description

technical field [0001] The invention relates to the technical field of backfilling in mining areas, in particular to a treatment method and device for filling pipelines with paste. Background technique [0002] After mining ore in the mine, a large number of goafs will be formed underground. The goafs are likely to cause safety problems such as surface subsidence and edge collapse. If the goafs are not dealt with in time, there will be safety hazards in the mining work. Therefore, It is necessary to carry out filling operations on the formed mining area, which can not only eliminate potential safety hazards, but also improve resource recovery rate and reduce loss rate and dilution rate. [0003] The existing method is to use paste to fill the formed mining area. Paste filling has the advantages of no segregation of slurry, no dehydration of the stope, good filling body homogeneity, and high strength. It is the best filling quality at present. A filling mode. However, due t...
