L'un des paramètres les plus importants utilisés dans la conception des structures rocheuses est le module de déformation. Cependant, ce paramètre est considéré comme une valeur fixe dans presque toutes les conceptions. Le module d'élasticité du matériau rocheux est utilisé dans les formules utilisées lors du calcul du module de déformation. Le module d'élasticité du matériau rocheux change avec la profondeur, c'est-à-dire la quantité de contrainte. Le module d'élasticité variable du matériau rocheux nécessite que le module de déformation de la masse rocheuse soit...

Coal produced in underground coal mines is transported to the earth by means of belt conveyors throughout long roadways. The combustion of belts in underground mining operations causes large number of employees to face great risks. Underground collieries have a different feature compared to other underground mines and structures. The main reason for this difference is that the transported material carries high-carbon containing coal. The most important cause of belt fires occurring in this type of underground mines is the hidden burning feature of coal. The combustion process that starts with...

Seismic waves carry all the geological and geotechnical characteristics (fault, number of discontinuities, discontinuity direction, slope, rock quality, groundwater, etc.) of the units they pass along the route they travel on. Therefore, seismic waves can be called the signature of the route it passes through. Let's call the blasting point as the zero point (source). If the zero-point form of the blast-induced seismic waves measured at a certain distance from the zero point (on the target) can be revealed and this form can be integrated into the dynamic numerical model, the effects that will...
