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 14 lines of surface rock movement in a mine, and the deformation values ​​of 18 monitoring points on the surface of the mining area were obtained through monitoring ( figure 1 ).

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

[0024] (1) For the mine described in step 1, select the rock mass deformation modulus E, the rock mass Poisson's ratio μ, and the filling body deformation modulus E * and filling Poisson's ratio μ * It is used as the deformation characteristic parameter of rock mass and filling body.

[0025] (2) Aiming at the current mining stage, establish a three-dimensional numerical model, and carry out E, μ, E * , μ * Orthogonal numerical experiment with 4 factors and 3 levels (E levels are 1GPa, 2GPa, 4GPa;...

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 decision-making method for mining engineering by filling method. Background technique [0002] Filling mining backfills waste rocks, tailings, waste water and other wastes into the underground stope to effectively control the pressure of the stope and reduce surface subsidence; it can also reduce waste discharge and realize green mining with no waste or less waste, thereby protecting Environment and Control of Geological Hazards. Compared with other mining methods, the backfill mining method is more complex and has lower mining production capacity, so the economic benefits of mining are relatively poor, and it is usually used for the mining of non-ferrous and precious metal ore bodies. As my country's environmental protection requirements for resource development become more and more stringent, not only the proportion of non-ferrous mine filling method mining has incr...
