Discontinuity Analysis at Ruschita Marble Quarry Using Televiewer and Scanline Techniques

Stone blocks, such as marble, granite, and sandstone, are natural materials with excellent properties. The most important dimension stone in Romania is Ruschita marble, a natural stone known for its resistance to wear and ability to maintain its natural beauty, regardless of its colour. Regarding colour palette, Ruschita marble stands out for its excellent quality to suit even the most demanding requirements. It is available in shades such as yellowish, orange, pale pink or pink, with a compact structure and characteristic veining. Ruschita is Romania's most famous marble deposit, exploited since the end of the 19th century. The quarry exploitation is conditioned by naturally occurring fractures and discontinuities, such as faults, joints, and fissures, precluding larger blocks excavating with more significant commercial value. This paper describes two largely used techniques for discontinuity investigation, namely the televiewer and scanline methods used at the Ruschita marble quarry

Environmental modelling - a modern tool towards sustainability

One way to solve environmental problems is through modelling. Humankind developed a series of models, from mental models, physical models to computer simulation models. Building a model assumes abstraction, simplifying the natural system by considering only the essential details and discarding irrelevant ones. Mapping the real worlds to the world of models is done by choosing an abstraction level and the corresponding modelling tool. The right abstraction level is paramount for any modelling project, depending on the real problem being analysed. In modern simulation modelling, there are three methods, each having a particular range of abstraction levels: system dynamics, discrete event (process-centric modelling) and agent-based models. Ecosystems and generally any environmental problems (real world) are complex dynamics that challenge our comprehension. Understanding the significant environmental challenges is vital to adopt adequate policies for a sustainable environment through modelling and simulation. Since our cognitive abilities are limited, we need a simulation of the environmental systems to see the dynamic patterns and how humans interact with the environment. Environmental modelling helps us understand complex systems by building mathematical models and running simulations using a high abstraction level. The system dynamics method of modelling and simulation is used to clarify the representation of the stocks and flows and the feedback process that control the flows and describe the dynamic behaviour (growth, decay, or oscillations) of complex systems over time. Modelling for prediction, understanding across time and spatial scales, and environmental systems disciplines is key for a sustainable future
