Problems solved by technology

[0003] Due to the particularity of underground filling conditions in each mine, the use of retaining walls is not exactly the same, and there is no complete set of design specifications for reference
At present, a lot of research has been done at home and abroad on the design strength of the filling retaining wall, but the design value is often too high, resulting in excessive strength and high cost of the retaining wall
At present, there is no systematic research on the force change law of the filling retaining wall, so it cannot provide reference for the design of the filling retaining wall

Embodiment Construction

[0035] Figure 1~5 It is the best embodiment of the present invention, below in conjunction with attached Figure 1~5 The present invention will be further described.

[0036] A device for simulating and testing the force change law of a filling retaining wall, including a test tube and a measuring device, the test tube is vertically arranged, the side of the test tube is provided with an opening and is closed by an elastic film 8, the measuring device is connected with the elastic film 8, and detects The force that the elastic film 8 is subjected to. The measuring device can measure the force on the elastic membrane 8, so as to measure the pressure of the mortar in the test tube on the elastic membrane 8, and then simulate the change law of the force on the filling retaining wall, and obtain the force of the retaining wall under different filling conditions. It can provide a reference for the design of the filling retaining wall. The test device has a simple structure and i...

Abstract

The invention discloses a test device and a test method for simulating the force variation law of a filling retaining wall, which belong to the technical field of mining engineering. It is characterized in that it includes a test tube and a measuring device, the test tube is vertically arranged, the side of the test tube is provided with an opening and is closed by an elastic film (8), the measuring device is connected with the elastic film (8), and detects the elastic film (8) received force. The force change law simulation test device of the filling retaining wall can simulate the force change law of the filling retaining wall, and obtain the force change law of the retaining wall under different filling conditions, so as to provide reference for the design of the filling retaining wall. This test The device has a simple structure and is easy to assemble. It can simulate the force change of the retaining wall under different filling materials and has a wide range of applications. The test method is simple to operate and can simulate the force of the retaining wall under different filling conditions. The pressure-time line graph can It well shows the changing law of the force on the retaining wall during the settlement of the tailings slurry, and the performance is intuitive.

Description

technical field [0001] The invention discloses a test device and a test method for simulating the force variation law of a filling retaining wall, which belong to the technical field of mining engineering. Background technique [0002] With the application of filling mining method in metal mines, related filling mining technology has been extensively studied, among which filling retaining wall technology plays a vital role in whether the goaf can be safely filled, and must be completed before filling. an important work. However, due to the unique role of filling material and the different characteristics of slurry pipeline transportation, many mines have encountered problems in the design and calculation of filling retaining walls. Due to the improper design of the retaining wall, the retaining wall collapsed or the slurry ran out during the filling process in some mines, causing serious losses. Therefore, when using the filling mining method, in order to ensure the safe m...
