example 1

[0057] Example 1: Determination of the optimal concentration of slurry when filling a single cavity.

[0058] One end of the slurry delivery hose 8 is connected to the inlet of the peristaltic pump 7 , one end of the slurry delivery hose 9 is connected to the outlet of the peristaltic pump 7 , and one end is connected to the central tube 10 . The auxiliary port plug 14 is screwed to all the auxiliary ports 18 on the chamber cover 13, the sleeve pipe 12 is screwed to the main port 19, the sleeve pipe 12 is provided with a liquid leakage groove 21 and the end is downward, and the liquid outlet 22 on the sleeve pipe 12 is connected with the External hose connection to waste. The cavity cover 13 is screwed onto the filling cavity 15, the central tube 10 is inserted into the casing 12, the central tube 10 is adjusted, and the bottom distance of the tube is fixed.

[0059]The filling chamber 15 is filled with brine. Pour industrial waste and brine into the mixing chamber 4 accordi...

example 2

[0062] Example 2: Determination of the optimum tube-to-bottom distance during double-cavity filling.

[0063] In the first mining area of ​​a salt mine, double-cavity mining is carried out by using the straight-flow method of wells. The well spacing is 74.78m, the average cavity height is 50m, and the simulated filling cavity height is 0.5m. According to the similar relationship, the distance between the two holes selected in the cavity cover 13 should be 0.75m. After measurement, there are two auxiliary ports with a distance of 0.75m.

[0064] Both the unused auxiliary port 18 and the main port 19 are tightened with the auxiliary (main) port plug 14. Take two auxiliary port hollow plugs 23, screw them on the selected auxiliary port, insert the central tube 10 into one of the auxiliary port hollow plugs 23, the outer end of the central tube 10 is connected to one end of the slurry delivery hose 9, and the liquid outlet hose 11 is inserted into the The other is a pair of hollo...

Abstract

The invention discloses a filling simulator for a salt rock cavern, which consists of a stirring device, a pumping device, a simulating salt rock cavern and an image collecting device, wherein the stirring device, the pumping device and the simulating salt rock cavern are connected by a mortar conveying hose and a mortar feeding hose; a camera of the image collecting device is arranged in the front of the simulating salt rock cavern and is controlled by a computer; and a master opening and auxiliary openings which are formed on a cavern cover are matched with a casing pipe, a central pipe, auxiliary opening hollow plugs, master opening plugs, so that the simulating salt rock cavern can realize the simulation of single caverns, dual caverns and multiple communicated caverns. The filling simulator has a simple structure, is convenient to use, distinct in equipment phenomena and multivariant in function, and can simulate the diffusion and settlement phenomena of filling slurry in cavernswith multiple shapes in brine under different filling processes and measure the horizontal migration distance and angles of repose of the caverns.

Description

technical field [0001] The invention belongs to the field of water-soluble mining tests of salt deposits, and more specifically relates to a salt cavity filling simulation device, which is suitable for the diffusion and settlement analysis of filling slurry in a salt cavity filled with brine, as well as the filling methods and methods of cavity bodies of different shapes. handicraft Research. Background technique [0002] Due to the good rheological properties of salt rock, the volume of abandoned salt caverns continues to shrink after the well is closed, which is likely to induce geological disasters such as ground subsidence, and in severe cases, large-scale sinkholes will appear, such as Dingyuan in Anhui and Zhoutian in Jiangxi recently. Large-scale ground subsidence induced by salt mine mining occurred, polluting the groundwater system and causing serious environmental pollution. Therefore, reasonable disposal of abandoned salt chambers has important environmental sign...
