expects that the pool of technology options will expand and shift away from highenergyuse, highmaintenance systems to lowenergyuse, lowmaintenance systems. Active or passive methods can remove or reduce the concentration of contaminants in MIW. The International Network for Acid Prevention''s GARD Guide considers active treatment as
The rise of Western European mining industry depended, of course, closely on the increasing weight of Western Europe on the stage of world history. Although the subject has sometimes been overlooked by historians, advances in Medieval mining and metallurgy made the flourishing of Western European civilization to a large extent possible.

MONITORING UNDERGROUND MINE DISPLACEMENT USING PHOTOGRAMMETRY AND LASER SCANNING Brent Slaker ABSTRACT Photogrammetry and laser scanning are remote sensing technologies with the potential to monitor movements of rock masses and their support systems in underground mine environments.
Each of the models is developed from first principles based on typical mining criteria for rock densities, swell factors, drill penetration rates, etc. Industrystandard estimating methods are used for equipment selection, personnel allocation, and cost estimation. These models are invaluable for early order ofmagnitude estimates.

Web hits and downloads continue as students and professors, miners, engineers, and mining executives embrace the Handbook as an invaluable source of practical
These test methods provide accurate and reliable analytical procedures to determine the chemical constituents of limestone, quicklime, and hydrated lime (see Note 1).The percentages of specific constituents which determine a material''s quality or fitness for use are of significance depending upon the purpose or end use of the material.
All of us are confronted daily – often unknowingly – confronted with geology: from the ground on which we live, past the concrete as part of a building''s foundation, to the copper in the mobile telephone, so much has to do with geology. ... ores and other mineral resources were already being extracted by mining methods 3500 years ago ...
MINE VENTILATION SYSTEMS Ventilation is the control of air movement, its amount, and direction. Although it contributes noth ing directly to the production phase of an operation, the lack of proper ventilation often will cause lower worker efficiency and decreased productivity, increased accident rates, and absenteeism.
