Title: Physics Of Coal And Mining Processes Authors: Alexeev, Anatoly D. Abstract: Fossil coal is a “living witness” of prehistoric times (from the Carboniferous to Jurassic), when the Earth was covered with impenetrable jungles, and equisetums, lycopodiums, and ferns thrived. Due to seismic cataclysms, the jungles were first buried under water and later under various rock layers. That started the transformation of wood material into coal—a process known as metamorphism. Meanwhile, the world’s oceans witnessed a similar process—the transformation of plankton into petroleum. Description: USE ONLY FOR ACADEMY PURPOSE.

Title: Rare Earth Elements in Ultramafic and Mafic Rocks and their Minerals: Main Types of Rocks. Rock-forming Minerals Authors: Lesnov, F. P. Abstract: Nowadays lanthanides or rare earths are recognized as a group of elements of the periodic table with unique chemical properties and extremely important for science. Although these elements were discovered long ago and their chemistry is well studied, their application in geology was made difficult due to their extremely low concentrations in most natural media and to difficulties in obtaining correct data on their contents in particular samples. In the latter half of last century these difficulties were overcome mostly due to the development and introduction of new devices and methods which provided a rather high level of sensibility and precision for determining the low concentrations of rare earth elements (REE) not only in rocks but in individual mineral crystals as well. At present, REE are widely used for solving many geological problems, including reconstructions of the geochemical evolution of the Earth and other planets of the solar system.

Title: Technical and Geoinformational Systems in Mining. Authors: Pivnyak, Genadiy; Bondarenko, Volodymyr; Kovalevs’ka, Iryna Abstract: General requirements for induction heating of machine parts connections with a purpose of their dismantling are substantiated. The methodology for the specific surface power and other mode parameters determining that meet formulated requirements is developed. The influence of electromagnetic field parameters on the character of thermal process development is shown. Description: USE ONLY FOR ACADEMY PURPOSE.

Title: Performance of Explosives and New Developments. Authors: Mohanty, Bibhu; Singh, Vinay Kumar Abstract: A review of ideal detonation theory, thermochemical computer codes for calculation of ideal detonation behavior and applications of these to blasting engineering is presented. This paper provides background for a first stage analysis of the ideal detonation process in an explosive composition and estimation of detonation parameters such as velocity of detonation and energy. Both these are critical parameters in design of blasts. Description: USE ONLY FOR ACADEMY PURPOSE.
