The flyrock from blasting operations can harm, damage or expose the workers of a particular worksite or the dwellers of a wider area of extractive activities (quarry, mine, construction site) to damage risks; in some cases even death might be caused, too. There are certain and different ideas and theoretical approaches regarding the evaluation of causes and the implementation of flyrock prevention measures to be taken, as well. This implementation, however, in practice requires a more delicate and rather professio...

Nickeliferrous laterite is a source of ferronickel alloy extracted by a pyro-metallurgical process. Laterite deposits found in Greece are mainly secondary depositions and their nickel content is about 1\%. Beneficiation of the run of mine ore is limited to the +1 mm fraction by magnetic or gravitational processes and its effect is rather unsatisfactory due to the insufficient liberation of the nickel bearing minerals. The mineralogical structure of the ore consists mainly of hematite nodules (pissoids) and quartz ...

PARAMETRICAL ADJUSTMENT OF GRAVIMETRIC NETWORKS BY INTRODUCING THE VELOCITY OF THE DRIFT AS AN ADDITIONAL UNKNOWN QUANTITY

(SGEM Scientific GeoConference, 2005, M. Ivanova)

Show more

A modification of the conventional adjustment model is proposed. Like this, the velocity of the drift is introduced as an additional unknown quantity. An argument about the priorities of the suggested approach, in comparison with the used at present methods for gravimetric measurements processing is done. The possibilities which the new adjustment model provide for an optimization of the whole measurements program in a gravimetric network are analyzed.

PETROLEUM SYSTEM AND PLAY CONCEPTS: DEEP WATER BALKANIDES - WESTERN BLACK SEA BASIN

(SGEM Scientific GeoConference, 2005, B. Wright, E. Higgins)

Show more

An ongoing geologic and geophysical investigation in the deep-water Black Sea, offshore Bulgaria reveals conditions suitable for hydrocarbon accumulations with giant field size potential. This potential lies within the buried offshore extension of the Paleogene Balkanide fold belt and its adjacent Eocene-Oligocene foreland basin, in water depths of 500-1,700 meters. With the benefit of onshore geologic studies and new offshore seismic acquisition and processing, it is possible to recognize and evaluate the basic e...
