... Abstract The industrial exploitation of the Carrara Marble dates back to I century B.C. with the Romans. After a black out in the Early Mediaeval age due to barbarian invasions, since XIII century the Carrara Marble has becoming more and more used for ornamental purposes and appreciated...

... Abstract The exploitation of geo-energies often leads to difficulties that rock mechanics helps to overcome. These essentially consist of instability problems caused by changes in the state of stress, associated pore pressures, and temperature. Besides the classical near field problem...

... in dynamic load on the support there is instability and the rockburst phenomena in excavations are observed. The stress concentration zones linked to edges or remnants of the old exploitation are the places where rockbursts have occurred most often. The performed numerical modeling showed, that under...

... (Balearic Islands, Spain) in what is now a highly touristic area (Fig. 1). There are documents testifying to the existence of the mines from the XIV century, but the height of their exploitation was between 1867 and 1909, when they were abandoned due to flooding in the richest part of the mine. Strangely...

A methodology created by robust mathematical tools combined with other techniques for calculating the instantaneous state piezometric water on the slope of the mine is presented. This application achieves make the data...

... Abstract There are several factors that affect the formation of localized rockfalls in self-supporting underground mines. Between these factors we can point out the type of material, the environmental conditions, the process of exploitation or the redistribution of stresses. All of them...

... Abstract Coal exploitation in the Upper Silesian Coal Basin is associated with rockburst hazard. This hazard is minimalized by active rockburst prevention, where torpedo blastings in roof-rocks take very important place. The estimation of the torpedo blasting effectiveness becomes significant...

... ABSTRACT The exploitation of deposits is a limited activity in time and soon or later every mine exploiting the given deposit will come to a phase of liquidation, which is accompanied by termination of pumping out the mine waters. This is shown by a rise of the groundwater table in the region...

... ABSTRACT: This paper deals with rock mechanics studies for the optimization of the design lay-out in the Osceola Valley ornamental stone basin (north-west Italy). The exploitation planning has to consider the different structural and geological situations observed in this area. The most...

A mathematical technique is proposed for prognostic rock displacement evaluation allowing for this effect...
