Condizione: Hervorragend. Zustand: Hervorragend | Seiten: 688 | Sprache: Englisch | Produktart: Bücher | This book represents a comprehensive geo-mechanical study of the magmatic rocks represented by a wide range of varieties; it is structured into three parts, experimental and interpretation of experimental data, showing the methodology to assess the quality of igneous rocks analyzed, and the results of theoretical and experimental research carried out on the analyzed rock types. A new ranking method is proposed, based on considering the rock characteristics as indicators of quantitative assessment, and the grading system, by given points, allowing the rocks framing in admissibility classes. Applying this evaluation system allows determining the specific parameters of the rock quality requirements, namely the conformity and unconformity degrees, and more specifically the safety level that these rocks can provide if they are used in the construction field, either as aggregates or as construction materials. The proposed method represents an appropriate tool for assessment and verification of the requirements regarding the quality of rocks used in construction. The last part includes a general classification of analyzed magmatic rocks based on the geomechanical assessment model.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book includes own research studies and results regarding, on the one hand, to the problem of stability - reliability of mining works in difficult conditions in geomechanical terms, and on the other hand, the research had also been subject to exploitation of rock salt, meaning micro and macroscopic behavior analysis of salt based on detailed laboratory geomechanical research and in situ, but also by analyzing the stability of underground workings executed in salt massif during operations, and the idea that underground voids created will have another destination after the exploitation of salt deposits. Particularly, the results of observations and in situ measurements performed in underground are presented, the correlation between the parameters that influence the stability of underground works, critical depth from which one can define the vertical behavior of the rock deformation, that is, limits the separation zone from the elastic behavior of the plastic behavior. A mathematical model was developed, which is based on the concept of entropy, a model that can analyze the stability of the pillars of any shape. 384 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book includes own studies and results obtained by the author in the field of rocks rheology and its implications in the stability - reliability of underground mining works; it was done out of a desire to open the knowledge horizon of rock mechanics and highlight its role in the underground constructions. Particularly, are presented the results of observations and in situ measurements performed in underground, the rheological results of studies conducted in the laboratory and the methodology to establish the rheological behavior models of the analyzed sedimentary rocks from Jiu Valley basin - Romania. Based on these results, it has been studying the mechanism of interaction rock - support taking into account the time. The geomechanical placement conditions of the main horizontal mining works, observations and in situ measurements well as results of their stability analysis showed that ensuring the reliability of main horizontal mining works should be achieved through imposed stability; that can be solved only by considering the time parameter, namely taking also into account the behavior of rocks in time. 548 pp. Englisch.…
