Problems solved by technology
The segregation of the aggregate in the paste filling will inevitably lead to settlement. During the transportation process, the settlement of the slurry will cause the pipeline to be blocked
Blockage not only affects the normal filling operation, but also causes significant economic losses to the entire filling system
The settlement of the aggregate reduces the strength of the filling paste, which may not achieve the expected control effect

Abstract
The invention discloses a device for testing settlement of aggregate in filling paste. The device comprises a test piece drum and a polarizability testing device, wherein the test piece drum is an organic glass cylinder provided with a base plate, the polarizability testing device comprises a power supply, an electrode, wires, a singlechip, a signal amplifier, a signal converter and a PC computer; the electrode is divided into a power supply electrode and a measuring electrode, the end of the upper part of the measuring electrode is connected with the signal amplifier by virtue of the wire, the signal amplifier is connected with the signal converter, and the signal converter is connected with the singlechip by virtue of the wire. The device disclosed by the invention has the advantages that whether the aggregate settles or not in a solidification process of the filling paste is judged by measuring changing situation of the polarizability of the test piece at different positions in a testing process, and the polarizability can be different because ions can be different at different positions; settlement of the aggregate in the filling paste is judged by measuring the polarizability at different parts, and time required for test is short; and test efficiency is high, and whether the aggregate settles can be rapidly judged.
Description
technical field [0001] The invention relates to a testing device and method for aggregate settlement in filling paste, belonging to the technical field of paste filling in coal mining. Background technique [0002] Paste filling mining can solve the damage caused by my country's coal mines to water resources, land, buildings, etc. Compared with traditional caving mining, it can prevent the collapse of gobs and protect the environment; it is conducive to improving the safety of mining ; It can effectively liberate the remaining coal pillars of the "three downs", improve the utilization rate of resources, and prolong the service life of the mine; effectively use abandoned gangue, etc., and carry out comprehensive utilization of waste. [0003] Paste filling refers to the method of making the material into a paste-like slurry with "no critical flow rate and no need for dehydration", through pump pressure and gravity, passing through the pipeline conveyor belt under the mine, and...
