Available in PDF, EPUB and Kindle. Book excerpt: The Denison-Potacan Potash Co. mine site is located southwest of Sussex, NB. As a follow-up to work done in Phases I and II, a study was conducted to assess the hanging wall response to mining, based on concern that the overburden rocks may be capable of storing a large magnitude of strain energy such that sudden brittle failure of that sequence would result in significant seismic activity. A microseismic system was installed to determine if hanging wall deformation occurring in response to mining was accompanied by seismic activity, and geomechanical codes GEOROC and VISCOT were verified by comparison of output with in-situ closure and stress measurements.

Download or read book Potash written by D.E. Garrett and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 744 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potash is the term generally given to potassium chloride, but it is also loosely applied to the various potassium compounds used in agriculture: po tassium sulfate, potassium nitrate or double salts of potassium and magne sium sulfate (generally langbeinite, K S0 • 2MgS0 ). Sometimes the var 2 4 4 ious compounds are differentiated by the terms muriate of potash, sulfate of potash, etc. When referring to ores, or in geology, all of the naturally found potassium salts are called "potash ores". However, originally potash referred only to crude potassium carbonate, since its sole source was the leaching of wood ashes in large pots. This "pot ash" product was generally recovered from near-seacoast plants, such as the saltwort bush, whose ashes were richer in potassium than sodium carbonate. Inland plant's ashes were generally higher in sodium carbonate, giving rise to the word alkali from the Arabic word for soda ash, al kali. The term was then carried over after potassium was discovered to form the latin word for it, kalium. The recovery of potash from ashes became a thriving small cottage industry throughout the world's coastal areas, and developing economies, such as the early set tlers in the United States were able to generate some much-needed income from its recovery and sale. This industry rapidly phased out with the advent of the LeBanc process for producing soda ash in 1792, and the discovery about the same time of the massive sodium-potassium nitrate deposits in the Atacama Desert of Chile.

Download or read book Geodesy written by P. Vanícek and published by Elsevier. This book was released on 2015-06-03 with total page 714 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geodesy: The Concepts, Second Edition focuses on the processes, approaches, and methodologies employed in geodesy, including gravity field and motions of the earth and geodetic methodology. The book first underscores the history of geodesy, mathematics and geodesy, and geodesy and other disciplines. Discussions focus on algebra, geometry, statistics, symbolic relation between geodesy and other sciences, applications of geodesy, and the historical beginnings of geodesy. The text then ponders on the structure of geodesy, as well as functions of geodesy and geodetic theory and practice. The publication examines the motions, gravity field, deformations in time, and size and shape of earth. Topics include tidal phenomena, tectonic deformations, actual shape of the earth, gravity anomaly and potential, and observed polar motion and spin velocity variations. The elements of geodetic methodology, classes of mathematical models, and formulation and solving of problems are also mentioned. The text is a dependable source of data for readers interested in the concepts involved in geodesy.
Download or read book Urban Surveying and Mapping written by T. J. Blachut and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea of writing a textbook on urban surveying and mapping originated with the Commission on Cartography of the Pan American Institute of Geography and History (PAIGH) because of the urgent need for planned and integrated surveying and mapping in urban communities of the American Hemisphere. It is obvious, however, that, with the exception of some European countries, the same situation exists in most cities of the world. The undersigned was asked to undertake the task. The task was not simple. The only available comprehensive text in the field 1 is Geodezja Miejska , which was published recently in Poland and reached the authors only after most of the present text was written. It is tailored to a very specific market and different requirements. Although it is an impressive book, it differs vastly from our own approach. Other reference texts are fragmentary or obsolete. During the last two decades, revolutionary changes have occurred in survey ing and mapping technology which have had a profound effect on actual procedures. In addition, the traditional concepts of urban surveying and map ping are undergoing rapid evolution. It is recognized that administration and planning require a great variety of continuously updated information which must be correlated with the actual physical fabric of the community, as de termined by surveying and mapping. Modern urban surveying and mapping is therefore the foundation of the broad and dynamic information system that is indispensable in any rational municipal effort.

Download or read book Three Dimensional Modeling with Geoscientific Information Systems written by A. Keith Turner and published by Springer Science & Business Media. This book was released on 1992 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geoscientific modelling has some unique requirements. Modern geological applications require increasingly quantitative and accurate rock property characerizations within the three-dimensional subsurface environment. this problem differs from that faced by most other fields due to a variety of technocal and economic constriants. Three-dimensional geoscientific modelling often relies on complex stochastic concepts and thus requires the extraction of information from large multiparameter data sets, and the representation and modification of complex, and uncertain geo-objects of interest.

This book was released on 2012-12-06 with total page 621 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the period April 25th to May 10th, 1984 the 3rd Course of the International School of Advanced Geodesy entitled "Optimization and Design of Geodetic Networks" took place in Erice. The main subject of the course is clear from the title and consisted mainly of that particular branch of network analysis, which results from applying general concepts of mathematical optimization to the design of geodetic networks. As al ways when dealing with optimization problems, there is an a-priori choice of the risk (or gain) function which should be minimized (or maximized) according to the specific interest of the "designer", which might be either of a scientific or of an economic nature or even of both. These aspects have been reviewed in an intro ductory lecture in which the particular needs arising in a geodetic context and their analytical representations are examined. Subsequently the main body of the optimization problem, which has been conven tionally divided into zero, first, second and third order design problems, is presented. The zero order design deals with the estimability problem, in other words with the definition of which parameters are estimable from a given set of observa tions. The problem results from the fact that coordinates of points are not univocally determined from the observations of relative quantities such as angles and distances, whence a problem of the optimal choice of a reference system, the so-called "datum problem" arises.
