Este curso introductorio sobre cianuro proporciona una introducción no técnica para el uso y manejo global del cianuro, incluyendo la producción de oro, química del cianuro, análisis, toxicidad, tratamiento, riesgos y manejo. Este curso está diseñado para proporcionar una amplia perspectiva del uso del cianuro y cómo se compara con otros químicos que se usan en el mundo. El cianuro fue utilizado por primera vez para la minería del oro en Nueva Zelandia y Sudáfrica hace más de un siglo. La cianuración sigue siendo uno de los métodos más eficientes para la lixiviación de oro y plata de las menas. El ácido cianhídrico (HCN) fue descubierto por el químico Sueco Carl Scheele en 1782. En gran parte, el temor y mal entendimiento que rodea al cianuro está relacionado con su uso en ejecuciones, como reactivo en guerra química y en incidentes como el de la cápsula de Tylenol y el suicidio en masa de Guyana hace muchos años. Existe mucha confusión y mala información en cuanto al impacto real del uso de cianuro en la industria minera de oro. Este curso introductorio intenta disipar los mitos y misterios que rodean al cianuro y proporcionar datos y cifras confiables. Cursos posteriores sobre el cianuro detallan aspectos técnicos específicos que se destacan en este curso introductorio. Este curso comienza con un examen de la producción, el uso y transporte del cianuro por el mundo, seguido por una discusión de sus propiedades técnicas, riesgos y manejo.

Underground Mine Backfill 1 - Introduction is the first in a set of two Underground Mine Backfill courses. This course is intended as an introduction to mine backfill properties, types, uses, mining methods and system layout. Underground Mine Backfill 2 - Slurry, Paste and Rock Fills reviews each backfill type and its preparation, distribution, stope preparation and placement practices as well as relevant safety and quality control issues. A review quiz can be found at the end of each section to evaluate your understanding of the material presented. The objective of the courses is to provide an overview of common underground mine backfill practices and technologies for mine technical personnel. The goals are to: Provide a standard from which operators can understand the basic principles and practices for using underground mine backfill. Provide an understanding of how critical the role of backfill and backfill personnel are for mining. Provide a common foundation for backfill training. Provide a uniform backfill terminology. Provide an understanding of the various stages of backfill systems. Provide an understanding of potential hazards to personnel and equipment safety in order to prevent backfill-related accidents. As many companies have site- and company-specific standards for their unique situations, training for specific operational duties is beyond the scope of this course and is left to mine site-training procedures. This course is not intended to replace existing mine training practices, but to complement them as a common reference. Authors James Archibald David O.

Underground Mining Methods and Equipment is intended as both a course and a technical reference for an audience of engineers, operators, contractors, consultants, regulators, practising geoscientists and students in the mining sector. The course provides a comprehensive introduction and reference for those who require a solid grounding in selection, design and development of mining methods and equipment. Mining method selection is based upon physical, geological, economical and environmental conditions and constraints. Equipment selection is based upon mining method and related production, performance and cost requirements. Principal course topics include the following. Introductions to underground mining methods, equipment and basic requirements. Mining methods and their application for room and pillar, sublevel stoping, shrinkage stoping, vertical retreat, cut and fill, longwall mining, sublevel caving, block caving, square set mining and other methods. Layout and design of underground mine development and equipment requirements. Equipment and selection for drilling, drifting, production, raising, shaft sinking, loading and hauling. Development and production estimation and costing (note - all costing and estimation information within the course were upgraded to current industry values as of 2012). This is a premium course which has been peer-reviewed by a committee appointed by the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) and the Society for Mining, Metallurgy and Exploration (SME).

Contouring of irregular spatial data by hand has been used by geoscientists for many decades. Contouring using a computer is relatively new and has become more widely used in the earth sciences only in the last 20 years. The availability of inexpensive microcomputer hardware and software makes the use of a computer for contouring affordable for nearly everyone. Gridding and contouring software has become flexible enough to satisfy nearly all needs for contouring with speed and convenience. Computer contouring is not perfect, so it is necessary to constantly be on guard and check results for artifacts and make sure the contour results are representative of the data. This course will help build awareness of what to watch for when using each contour method, when a method is most suitable, and when it is not. Since the early 1980's, we have experienced a significant increase in access to computer programs for contouring, as well as a large variety of computer algorithms. Books have been written about the algorithms and how they are used. The purpose of this course is to pull together information on the most commonly used contouring algorithms and reveal the 'secrets' of how and why they are used. These 'secrets' are not really secrets, but to find all this information you have to dig through many books, use the algorithms (hundreds of times) and observe results. We have explored all these resources for you and present the findings in this course. Hand contouring is still done by some people, and the first section of the course covers hand contouring methods, when to use them, and the pitfalls to avoid. Understanding hand contouring is a first step to using contour software effectively. Author Betty L. Gibbs Dr. Stephen A.
