Embodiment Construction

[0038] The inclinometer used in this example is the SAA inclinometer produced in Canada.

[0039] Below, the implementation of this patent will be introduced by taking the Qianyanshan Iron Mine from open-pit to underground mining and the model test research on waterproofing measures at the bottom of the pit as an example.

[0040] In this embodiment, the device for simulating the shifting of iron ore from open-pit to underground mining to induce rock formation movement is as follows: Figure 2 to Figure 8 As shown, it includes model box 1, ore body simulation box 3, masonry module 4 and transmission system 2;

[0041] The model box 1 is used to place the ore body simulation box 3 and the masonry module 4 after size reduction according to the actual mining area. The ore body simulation box 3 is a simulated ore body similar material to be excavated. Extract the box body of the ore body simulation box 3 to simulate the deformation and stress changes of similar materials in the o...

Abstract

The invention belongs to the technical field of mining rock mass mechanics engineering, and specifically relates to a device and a method of simulating iron ore open pit-into-underground mining induced strata movement. According to the device, a 3D physical model taking the actual joint fissure condition of a rock mass into consideration is built by use of a most similar material proportioning plan, so as to reproduce the whole process of strata movement and destruction induced by mining and the laws of deformation and destruction and to provide reasonable and effective suggestions for the prevention and control of geological disasters in a mine environment.

Description

technical field [0001] The invention belongs to the technical field of mine rock mechanics engineering, and in particular relates to a device and a method for simulating the movement of rock layers induced by iron ore open-pit to underground mining. Background technique [0002] Mineral resources are the material basis for the development of the national economy. With the continuous development of economic construction, the demand for mineral resources in our society is increasing day by day, and the depth of mining is also increasing. For a long time, we have paid attention to the economic benefits brought by mining to the society, but to a certain extent, we have ignored a series of problems in the process of mining. For example, mine environmental geological problems, unreasonable development lead to mine ecological environment damage, etc. These problems not only affect the safe production of mines, but also restrict the development of social economy. Among them, mine e...
