Numerical Simulations of Geomechanical State of Rock Mass Prior to Seismic Events Occurrence: Case Study From a Polish Copper Mine Aided by FEM 3D Approach
Witold Pytel, Piotr Mertuszka, Tristan Jones +1
The biggest risk to operations in Polish copper is high-energy seismic tremors where hypocenters are located within the main roof strata. These phenomena occur often in the areas w…
Geomechanical Risk Analysis for the Historical Salt Cavern Saurau in Wieliczka Mine
Witold Pytel, Jozef Parchanowicz, Piotr Mertuszka
Based on the finite element method formulated in three dimensions, a selected area of the salt mine has been modeled, embracing totally 2 separated, historically valuable mine room…
Seismic peak partcile velocity and acceleration response to mining faces firing in a light of numerical modeling and underground measurements
Witold Pytel, Piotr Mertuszka, Adam Lurka +2
Extraction of the copper ore deposit in the Legnica-Glogow Copper Basin in Poland is usually associated with high seismic activity. In order to face this threats, a number of organ…
Roof fall hazard due to blasting activity in the light of numerical modeling and underground measurements
Witold Pytel, Krzysztof Fulawka, Piotr Mertuszka +1
One of the major problems associated with exploitation of the copper ore deposit in underground mines in Poland is the local disturbance in a state of stable equilibrium manifested…
Numerical modeling of rockmass behaviour due to blasting operations in underground mines
Witold Pytel, Piotr Mertuszka, Krzysztof Fulawka +2
Antropogenic seismicity is one of the most important geomechanical hazard encountered in Polish deep copper mines. Obviously, it may have a negative impact on the peoples safety an…
Blasting parameters alternate selection as a tool for elastic wave effect amplification at potentially instable locations within main roof strata
Witold Pytel, Piotr Mertuszka
The exploitation of copper ore deposits in Polish underground mines is performed primarily by the use of blasting technology which seems to be relatively well suited to the hardnes…
