STABLE CRACK PROPAGATION STUDIES IN MARBLE AND TRAVERTINE

(SGEM Scientific GeoConference, 2007, I. Ozkan, N. Bilim, H. Ozsen)

Show more

The crack propagation researches carried out on rock and rock mass are important in mining, petroleum and natural gas engineering studies. It is assumed that crack propagation is an important design parameter in underground and open-pit mining applications. It has positive effects in some mining activities such as drilling, blasting, excavating, block caving but also negative effects due to cracks formed around mine roadways, tunnels and in landslides. In this research, the marble and travertine were selected as n...

STUDYING THE EFFECT OF MECHANICAL PROPERTIES OF DISCONTINUITIES ON THE SLOPE STABILITY IN PART OF ANGOURAN OPEN PIT MINE, IRAN

(SGEM Scientific GeoConference, 2007, Z. Naghadehi, R. Torabi, K. Kakaie)

Show more

Evaluation of stability of slopes is an important part of open pit mines planning and design due to economic and safety considerations. Slope failure can cause disruption to mine operations, loss of lives and damage to equipments. The different kinds and origins of discontinuities play a dominant role in the failure of rocks and hence in mine slopes stabilities. In this paper, the effect of mechanical properties of discontinuities on these phenomena is investigated. Angouran lead-zinc open pit mine is situated app...

(SGEM Scientific GeoConference, 2006, P. Pavlov, V. Kashamova)

Show more

Geographic Information System (GIS) are gradually gaining greater importance in the course of modeling of processes and phenomena in the surrounding environment. The mining is also affected by those systems. They use not only powerful tools for modeling and visualization of real objects in the 3D, but also statistical analyses. Some of the features of ArcGIS [1] for 3D modeling, visualization and statistical analyses on quarry and mines are described in the article.

APPLYING THE BOTH GEOSTATISTICAL ESTIMATION AND THE SEQUENTIAL GAUSSIAN SIMULATION WITHIN THE CHOGHART FE DEPOSIT

(SGEM Scientific GeoConference, 2006, O. Asghari, A. Hezarkhani)

Show more

To carry out the geostatistical studies, a spherical model was fitted over an empirical variogram. Plotting the empirical variogram in different directions, and it showed that there are neither geometric nor regional anisotropy. For simulating via Sequential Gaussian Simulation (SGS) method, data were transferred to standard normal and then simulated 100 times (in this way 100 realizations were created). All of the realizations were honor to histogram and the variogram, so all realizations are valid. E\_Type and p...

ASSESSMENT OF THE CHARACTERISTICS AND METHODS FOR TREATMENT OF LANDFILL GAS, EXTRACTED FROM LANDFILL FOR NON- HAZARDOUS WASTE “SUHODOL”

(SGEM Scientific GeoConference, 2006, I. Ganev, B. Dimitrov)

Show more

The quantity and the content of the landfill gas, emitted/extracted from landfill for non-hazardous waste “Suhodol” have been studied. Modeling calculations have been executed and forecast data for the quantity of the emitted and utilized landfill gas for the period till 2040 have been done. Methods for the treatment of the landfill gas, as it consists of methane - a powerful greenhouse gas, have been presented. The applicability of the presented different methods for Landfill “Suhodol” has been assessed. ...

AUTOMATED SYSTEM FOR MANAGEMENT OF QUALITY OF THE EXTRACTED ORE IN OPENCAST MINE FOR MASS DETONATION

(SGEM Scientific GeoConference, 2006, M. Mazhdrakov, D. Benov)

Show more

The system is intended for operatively planning and management of the quality of extracted ore in real time. The system includes following features: Creating and maintenance of data base which contains the numeral samplers of the detonated fields, the needed technical and technological indicators etc. Planning of the extracted activities for period, day, shift and part of a shift by different optimization measures. Distribution of the extraction between the coal-faces. Reverse connection with GPS information relat...

BENTONITE LOCALITIES IN THE NORTH -BOHEMIAN BROWN-COAL BASIN AND THEIR POTENTIAL UTILIZATION AS CLAY SORBENTS

(SGEM Scientific GeoConference, 2006, M. Rehor, T. Lang, V. Cablik)

Show more

A significant range of the landscaped damaged by brown coal mining is one of the base problems of the region of the North Bohemian Brown Coal Basin. The proper application of fertilizable rocks to sterile and phyto-toxic sits is the condition of the success of reclamation works. Natural clayey sorbents are usually of very good use, but the North Bohemian Basin is quite poor with them. Bentonite deposits are significant exceptions. They are a part of tertiary vulcanodetritic strata of the subsoil of a coal seam. Th...

BIODEGRADATION OF HYDROGEN SULPHIDE (H2S) FROM THE WASTE GASES BY A PACKING MATERIALS COLUMN

(SGEM Scientific GeoConference, 2006, S. Dursun)

Show more

Many industrial processes and sewage treatment facilities produce odours, most of which are of decomposed sulphur compounds. Hydrogen sulphide (H2S), which is a very toxic and corrosive gas, may be the standard indicator among the obnoxious odours and therefore the amount released into the air is required to be regulated strictly. Hydrogen sulphide was efficiently removed from contaminated air by a pilot-scale bio-filter; a column prepared with soil, sawdust and activated sludge materials from the leather industry...
