In coal mining, as the mining depth increases, a complex mechanical environment of “high ground stress”, temperature”, karst water pressure”, and “mining disturbance”, namely “three highs one disturbance” appears. Many roadways have characteristics soft rock with large deformation, pressure, difficult support, high support cost, which brings severe challenges to safe efficient production mines....

Underground stope stability has important implications for the safety and efficiency of metal mining, especially when there are subsidence zones above. To analyze around area Hongling ore body, this paper innovatively adopts 3Dmine–Rhino3D–FLAC3D coupled modeling numerical method to model predict excavation process area; it monitors analyzes displacement stress-distribution changes in a selecte...

This paper presents a combination of geometric reconstructions of the Century Zn–Pb–Ag deposit, and finite-difference modelling of coupled deformation and fluid flow. Our intention is to demonstrate that these computer-based applications represent a new approach in testing ore genesis models. We use a ‘‘visiometric’’ approach, utilising GoCad 3D structural and property modelling. Computer visua...

To achieve a successful and effective operation, the transition from open pit to underground mining requires accurate planning analysis. Numerical modeling utilizing programs like FLAC3D has been an important tool for simulating analyzing complicated geomechanical behavior connected with this shift in recent years. The use of develop model switch coal soft rocks using room pillar method is expl...

There is significant interaction between the new supporting structure and existing adjacent retaining wall in dredging excavation project of urban rivers. In addition, three factors, spatial location, stiffness structures, soil conditions two sides will exert effects on bearing properties structures. Combined with an actual project, FLAC3D software was applied to analyze influencing rule U-shap...

Based on the engineering background of providing advance support for working face mining roadways, this paper studies reasonable technology roadway roofs by combining theoretical analysis, numerical simulation, and field tests. geological conditions 1304 Yineng Coal Mine, FLAC3D simulation software was used to compare analyze effects original single hydraulic prop bolt-mesh-cable without prop. ...

The Dayingezhuang orogenic gold deposit, located in the northwestern Jiaodong Peninsula, is hosted by Zhaoping detachment fault, but paleostress regime during mineralization period remains poorly understood. In this study, a series of numerical modeling experiments with variable stress conditions were carried out using FLAC3D software to determine orientation and fluid migration processes ore-f...

Uniaxial compressive stress-strain curves of several groups basalt fiber crumb rubber mortars (BF-CRM) with different contents are tested. By comparing the GZH model, improved values parameters BF-CRM constitutive model based on obtained. Then, taking supporting scheme main substation mine as background, using FLAC3D to simulate roadway support, replace ordinary in original and combining triaxi...
