Добрый день, Коллеги. Важное сообщение, просьба принять участие. Музей Ферсмана ищет помощь для реставрационных работ в помещении. Подробности по ссылке
This report constitutes a new descriptive model for epithermal gold-silver deposits. It summarizes characteristics of known deposits, including their geological, geophysical, geochemical, and geoenvironmental aspects. Models concerning the genesis of epithermal gold-silver deposits are discussed. How descriptive and genetic aspects of the model can be applied to mineral exploration and resource assessment of undiscovered deposits is described.
This document provides an overview of the Deswik.CAD object model and scripting interface. The document does cover some specifics of the programming and vb language uses, but is not designed as an in depth programming reference. The Deswik Scripting language closely follows the VB.NET Framework 4 as much as possible. Bearing in mind that it does NOT execute the code in the .NET JIT compiler (it has its own compiler). For this reason it is possible to use the Microsoft VB.NET web resources when looking for syntax information. There are likely some code syntaxes and methods which Deswik has not encountered. Should you find one of these cases please contact support and we will rectify as quickly as possible. <...>
Мы понимаем, что некоторые участники курса Deswik «Проектирование карьеров для добычи металлов» могут быть новичками в проектировании карьеров и нуждаться в рекомендациях по выполнению проекта.
Эта статья написана с учетом этой потребности и предназначена специально для помощи в компьютерном проектировании карьеров, то есть в руководстве по геометрическому проектированию. Она не претендует на полноту охвата общих принципов проектирования и эксплуатации карьеров.
This tutorial provides an introduction to the common tools and functions contained within Deswik.CAD in an Open Pit Hard Rock operation, however as this tutorial is an introduction to Deswik.CAD functionality, the learning’s can be applied generally.
This tutorial is designed to be used in conjunction with the training data folder 3.01 Intro to CAD Open Pit Hard Rock containing all of the training data, software files and a completed set of CAD exercises. <...>
Deswik.SO (Stope Optimizer) is a strategic mine planning tool that automates the design of stope shapes for a range of stoping methods for underground mines. The goal is to maximize the value of an orebody given the constraints using a certain mining method and design parameters. The outputs (stope wireframes, section strings and reports) are suitable for use in strategic and tactical planning <...>
The following process flow illustrates the steps required to complete an open pit design by either slicing the pit into Bench’s by Elevations, or doing more detailed design and breaking it out into blast polygons <...>
Azimuth and gradient search parameters allow the user to define the search direction of the spatial link. Azimuth search parameters can be used to link from undercut rings to first task in drawpoint drive using defined azimuth search direction, this will drive the direction of the SLC front. Gradient search parameters are similar, an example being stope linking in narrow vein steeply dipping stopes. <...>
In recent years, an increasing number of studies have used single-grain age dating of detrital sediments to obtain information on sediment provenance, the thermal history and exhumation of sediment source areas, and landscape evolution. In order to highlight the value of this current development in geological research, we based this volume on papers presented in a session on detrital thermochonology at the 2002 Geological Society of America Annual Meeting held in Denver, Colorado. This Special Paper provides a short overview of the different, nowadays commonly used, dating techniques in detrital thermochronology, followed by discussion of some of the methodological aspects of detrital thermochronology (in the first two manuscripts) and of a variety of applications of detrital thermochronology, demonstrated in several regional case studies. <...>
