The integrity of tunnel structures deployed in difficult geological conditions such as expansive soils can be improved by incorporating compressible layers the lining. Such lining materials obtained embedding weak inclusions (Expanded polystyrene, Expanded glass beads, Air voids) into a cement paste material. material properties these individual constituents well their geometry affect overall b...

The article describes the research of coal and gas outburst prediction technology and the new problems they face in the modern mining. It also describes the superiority of neural network technology in dealing with complex geological conditions. It refers to the possibility and necessity of combination of the coal and gas outburst prediction and artificial neural networks, and other hightechnolo...

1881). These provide a wealth of detailed information about Lyell's life, though with frequent and often tantalizing gaps, but they make no attempt to trace the development of his scientific work nor to estimate it critically. They shun controversy absolutely. In 1901 T. G. Bonney of Cambridge University issued a short popular life, Charles Lyell and Modern Geology, which, despite its brevity, ...

Reservoir heterogeneities exist at several length scales. Reservoir properties will depend on the scale that we are analysing on the reservoir (from core to grid block). Facies are normally identified in cores and classified based on microscopic and small scale features such as lithology, grain size, texture, sedimentary structure, colour and fossil content. However, facies information is only ...

Subject analysis of the potential of spontaneous combustion in coal layers with analytical and numerical methods has been always considered as a difficult task because of the complexity of the coal behavior and the number of factors influencing it. Empirical methods, due to accounting for certain and specific factors, have not accuracy and efficiency for all positions. The Rock Engineering Syst...

The use of digital information in geological fields is becoming very important. Thus, informatization in geological surveys should not stagnate as a result of the level of data accumulation. The integration and sharing of distributed, multi-source, heterogeneous geological information is an open problem in geological domains. Applications and services use geological spatial data with many featu...

to AI. An automated tool can do boring and repetitive reasoning, freeing experts to do more difficult and creative work. Indirectly, it can make explicit the knowledge and reasoning used by experts in the field. Finally, an automated tool can consider all possibilities, sometimes exploring scenarios that human experts may miss. This article discusses automating reasoning for dating geological l...
