Introductory Mining Engineering by Howard L Hartman :: Free Ebook in PDF



A beginning text and elementary reference book in mining engineering which adopts both a quantitative and a numerical approach. Provides in-depth treatment of the applications of mining engineering while reinforcing material with clear, complete analyses of special topics as well as numerical examples and problems.
Initial chapters are devoted to fundamentals, explaining the four stages of mining - prospecting, exploration, development, exploitation- and the unit operations of mining. The text continues with coverage of surface mining and underground mining. Highlights novel methods and provides case studies, answers to selected problems, extensive references and bibliography, and both English and SI or metric units.

CAPITAL AND OPERATING COST ESTIMATING SYSTEM


CAPITAL AND OPERATING COST ESTIMATING SYSTEM A MANUAL FOR MINING AND BENEFICIATION OF METALLIC AND NONMETALLIC MINERALS EXCEPT FOSSIL FUELS IN THE UNITED STATES AND CANADA Mining relies on anomalies within the surface of the earth for a base of activity. Mining and evaluation engineering are confronted repeatedly with problems of determining how and at what rate a particular deposit can be mined, how to get the equipment, personnel, and money for mining and processing, and how to set up the related infrastructure. When these problems are resolved, the engineer becomes involved in financial considerations. For example, what is the ratio of equity capital to borrowings, and what is the rate of return that may be achieved before a recommendation for the approval or rejection of the property can be made to management? Articles on cost for site-specific operations appear frequently in the technical literature. They may be useful if an engineer is considering a similar property, but this is seldom the case. Often the engineer is required to consider specially designed extraction and treatment methods applicable to unique or nearly unique deposits. In addition, the engineer is plagued by rapid changes in capital and operating costs. Recognizing this situation, the Bureau of Mines undertook the development of a methodology or cost system, usable by a mine evaluation engineer in generating capital and operating costs applicable to a feasibility study of a particular property or operation. This handbook, the product of this undertaking, is not intended to be the final solution to the problem of cost determination; it is also not a "black box" usable by the unskilled. It will, hopefully, be a useful adjunct to the "tool kit" of mining engineers responsible for property evaluation. Periodic updating and refining of the important data on which the handbook is based will improve its usefulness in the future

TALPAC software tutorial (English, spanish, Indonesian)

TALPAC is a software system that is used for determining the productivity and economics of truck and loader haulage systems, using logic that models real haulage situations.
TALPAC allows the study of most factors affecting productivity and the sensitivity of productivity to these factors.
Within TALPAC, you specify the haul route the truck is to operate over, which truck or group of trucks is to be used, the loading unit to be used and the operating limitations (eg. speed limits, surface conditions, etc). You also specify the loading strategy, material characteristics and work roster applicable to the fleet. TALPAC takes this raw data and performs a number of functions on it, including production analysis, loading analysis, discounted cost analysis and optimisation of fleet size, motor power, payload, etc.
