Mine-filling pipage test method and special equipment

Abstract

The invention relates to a mine-filling pipage test method and special equipment, which belong to the technical field of cemented filling of full tailings of mines. The technical scheme is as follows: the special equipment comprises a hopper (1), a delivery pipe (2), a detachable pipeline stopper (4) and supports (5), wherein the delivery pipe is arranged on the supports and is provided with an L-shaped pipeline structure formed by a horizontal pipeline and a vertical pipeline; the hopper is vertically distributed and is connected with one end of the vertical pipeline of the delivery pipe; and the other end of the horizontal pipeline of the delivery pipe is provided with the detachable pipeline stopper. The test equipment disclosed by the invention is simple, is easy to operate and is dispensed with any on-line detection instrument, such as a concentration meter, a flowmeter, a pressure gauge, and the like; and only simple common measuring tools such as a stopwatch, a box ruler, and the like are needed, the flow characteristic of the tailings in the delivery process and on-way resistance losses of the pipelines can be mastered within a short time, the yield shear stress of slurry, the rheological factor of the slurry and resistance losses i of the pipelines at different flow rates are obtained, the requirements of mine-filling designs and the production are satisfied, the cost is low, and the popularization and the application are easy.

Description

technical field [0001] The invention relates to a mine filling pipeline transport test method and special equipment, in particular to a pipeline transport test method capable of quickly grasping the transport characteristics of full tailings high-concentration cemented slurry, belonging to the technical field of mine full tailings cemented filling. Background technique [0002] The high-concentration filling system needs the best self-flowing conveying parameters in the design and commissioning process, such as flow rate, concentration, filling line, etc. If these parameters are not selected properly, the slurry is prone to blockage, dissatisfaction during the conveying process, and pipe The purpose of the pipeline transportation test is to obtain the following parameters: the yield shear stress of the slurry , Slurry rheological coefficient and pipeline resistance loss i (Pa / m) at different flow rates. Due to the different ore properties and beneficiation processes in ...

AI Technical Summary

Problems solved by technology

The loop pipe transportation test of the background technology has the advantage of being able to measure the loss of the slurry at different speeds and flow velocities on site at different ratios and different concentrations, and obtain design parameters suitable for high concentrations and paste filling systems. The existing problems are: The test consumes manpower, material resources and takes too long to be carried out in all mines
