Embodiment 1

[0022] Step 1: Use GPS deformation monitoring technology to monitor the surface deformation of the mining area in real time. 18 GPS deformation monitoring points were set up for the surface rock movement on the 14th line of a mine, and the deformation values ​​of 18 monitoring points on the surface of the mining area were obtained ( figure 1 ).

[0023] Step 2: Obtain the deformation characteristic parameters of the rock mass and the filling body at the current mining stage.

[0024] (1) For the mine mentioned in step 1, select the rock mass deformation modulus E, the rock mass Poisson's ratio μ, and the backfill deformation modulus E * Poisson's ratio μ * As the deformation characteristic parameter of rock mass and backfill.

[0025] (2) According to the current mining stage, establish a three-dimensional numerical model to perform E, μ, E * , Μ * Orthogonal numerical experiment with 4 factors and 3 levels (E level is 1GPa, 2GPa, 4GPa; μ level is 0.16, 0.18, 0.20; E * The level is ...

Abstract

The invention discloses a safe and highly efficient filling mining engineering decision method integrating monitoring technology, a backstoping scheme decision method and stope catastrophe and unstability risk probability calculating, so that the filling-method mining can achieve scientific backstoping scheme decision-making and rationalization of catastrophe risk control so as to further achieve safe, highly-efficient and low-cost production of filling-method mining in complex mines which are difficult to mine.

Description

Technical field [0001] The invention belongs to the field of filling mining, and in particular relates to a filling method mining engineering decision-making method. Background technique [0002] Filling method mining backfills waste rock, tailings, waste water and other wastes to the underground stope, effectively controlling the stope site pressure and reducing surface subsidence; it can also reduce waste discharge, realize no waste or less waste green mining, thereby protecting Environment and geological disaster control. Compared with other mining methods, the filling mining method is more complicated and the mining production capacity is lower, so the mining economic benefits are relatively poor, and it is usually used for the mining of non-ferrous and precious metal ore bodies. As my country's requirements for resource development and environmental protection become more and more stringent, not only the proportion of non-ferrous mines filling method mining is rapidly incre...
