TRANSITION FROM OPEN PIT COAL MINE TO THE UNDERGROUND MINE IN SOFT ROCKS

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 explored abstract. It presents development analyze simulate complex dynamics transition. significant considerations that went into developing model, such as geotechnical characteristics, rock mass behavior, mine design parameters, are highlighted highlights how essential proper input data producing reliable simulations forecasts rocks. usage tracking wall stability during period, evaluating influence on nearby infrastructure, optimizing covered models flexibility allows investigation various conditions offers valuable insight about process. research emphasizes potential lead decision-making through detailed analysis choosing appropriate width main entrance cross section stopes their interpretation. it understand deposit, optimize mines ensure safety employees. utilized recover resources deep mines, results can help improve efficiency, sustainability, risk prevention.
