LEVELLING STAVES COMPARATOR ON THE BASIS OF INCREMENTAL MEASURING SYSTEM

(SGEM Scientific GeoConference, 2008, D. Barkovic, M. Zrinjski, T. Debeljak)

Show more

Modern technology in the production of geodetic instruments and accessories needed for measuring basic quantities (distance and angle) has reached high level. In the filed of geometric levelling, colour layers are put on invar tapes very precisely with measuring uncertainty of 10–50 $\mu$m. These tapes present working scale on invar levelling staves. Using modern precise level (optical of digital) one can read the smallest detail on invar levelling staff with measuring uncertainty of 0.01 mm. Hence, it is obviou...

LONG TERM PRODUCTION SCHEDULING OF OPEN PIT MINES, A REVIEW OF OLD AND NEW ALGORITHMS

(SGEM Scientific GeoConference, 2008, S. M. ALI Hosseini, R. Kakaie, M. Ataei)

Show more

Since long term production scheduling deals with movement of ore and waste during the life of a mine, it has a significant effect on the cash flow of a mining operation. Therefore, mine planners often seek to optimize the production schedule with respect to a given criterion. The most commonly used criterion in long term scheduling optimization is to maximize net present value (NPV). The process involves sequencing of ore blocks or parcels to be mined in each period over the life of the mine subject to precedence ...

Show more

The Estonian kukersite is the largest oil shale resource in the world used industrially today. The majority of mined oil shale is utilized for electricity and heat production. About 20\% of all of the oil shale extracted annually is used for retorting shale-oil and shale-gas, after which large amount of environmentally hazardous solid retort residue – semi-coke is left over. Production of 1 tonne of shale-oil is accompanied by almost 3 tonnes of semi-coke waste. During more than 80 years of operation over 110 mi...

The objective is the study of filtering tissue permeability and the characterization by means of permeability tests, of the process of coal particles retention in breath protection filters. The porosity of a filter, defined as the ratio between the void volume inside its fibres and the total volume, is a static parameter that provides point source information about the initial conditions of the filtering tissue. When excessive deposition of particles on the fibres happens, there is an increase of resistance to the...

Environmental large-scale contamination in surrounding of abandoned Sb-deposits in Slovakia by toxic elements (Sb, As, Zn, Pb, Cu...) as result of long-time mining activity is still undiscovered field. Surroundings of abandoned antimony deposit Popro\vc bear high concentrations of toxic contaminants mainly of sulfide relative minerals. Pollution resulting from long-time mining activity was observed in area adjacent to adit Agnes showing Sb concentrations within values 4 700 – 10 000 mg.kg-1 and maximum As concen...

The Zbudza deposit is an important (major) deposit of halite within Slovakia but also Europe. It is possible establish that halite deposit Zbudza features attractive deposit about qualitative and quantitative aspect. It has important function on the part of selfsufficienty Slovak Republic in the production of salt and also in posse intersection to European trade. The economic effectiveness of financial investment is dependent from mining and process technology on the deposit. The investment efficiency is appreciat...

TECHNICAL CHARACTERISTICS AND POSSIBILITY OF USING LIMESTONE MASSIF "RGOTINA ROCK" NEAR BOR

(SGEM Scientific GeoConference, 2008, S. Krstic, M. Ljubojev, V. Ljubojev)

Show more

Limestone massif "Rgotina Rock" has, from a topographical point of view a remarkable, and from a mining point of view, a favourable position of occurrence. It extends in the form of a limestone reef, with the highest peak in its central part (top of Rgotina Rock). Mining has started in 1961. ”Kop 2”, in 1965. ”Kop 3” and in “Kop 5“ 1969. Mining, with changeable production volume and with occasional stopping of works, is in effect even today. Application of mineral raw material from this deposit, apart ...

TECHNICAL ECONOMICAL AND ENVIRONMENTAL EVALUATION OF VESTIGE MATERIAL EXPLOITATION FROM THE TREPCA MINES

(SGEM Scientific GeoConference, 2008, S. Kastrati, M. Hetemi, I. Zeqiri)

Show more

Actual circumstances of the old storages are treated, created from the enrichment processes in the Trepca Flotation plant, Kishnica’s and Albanik (ex Leposavic) mines. According to the existing documentation there are dragged out more than 60m ton of rich minerals with Pb, Zn, Ag, Au, pyrite and other minerals from Trepca mines. This process was developed in the flotation plants of Stanterg, Kishnica and Albanik mines, achieved in a dispersive complex, as well as during the physical-chemical process. The separat...

TEXTURAL DISTRIBUTION OF ARSENIC AND HEAVY METALS IN SOILS AFFECTED BY ABANDONED MINING WORKS: CONSEQUENCES FOR SOIL WASHING

(SGEM Scientific GeoConference, 2008, F. Gonzalez-Coto, C. Sierra, R.VILLA, J. R. GALLEGO J.M. Menandez-Aguado)

Show more

We introduce an example of a detailed study of soil texture and geochemistry with the aim of designing appropriate soil washing systems. Concretely, we have studied soils affected by the mining works of “Los Rueldos” (Asturias, Spain). After an initial characterization, composite, representative samples were taken and ICP-MS analysis was carried out. Results showed very high concentrations of As, and significant presence of heavy metals such Hg, Pb and Zn specially in silt-clay fractions obtained after wet sie...

This paper presents the results of ground vibration measurements and environmental issues occurred on tunnel blasting activities during KavacД±k-Beykoz waste water tunnel construction under a residential area in Istanbul, Turkey. Within the scope of the study, the blasting pattern of tunnel was engineered by using Tunnel 2000 design software. 5 events in 5 shots at S2 shaft tunnels, , 6 events in 6 shots at S4 shaft tunnels, , 32 events in 32 shots at S6-shaft tunnels and, 7 events in 7 shots at S7 shaft tunnels w...

THE APPLICATION OF FeO/H2O2 FOR COLOR REMOVAL

(SGEM Scientific GeoConference, 2008, S. Sahinkaya, A. Aygun, M. F. Sevimli)

Show more

The decolorization of C.I. Reactive Orange 36 (RO 36) by using Fenton-like process (Fe0/H2O2) was studied. Batch experiments were carried out for investigation of optimum operational conditions such as pH, H2O2 and Fe0 (iron powder) dosages. The results show that Fenton-like process is an efficient process to remove color from synthetic textile wastewater including RO 36 and polyvynil alcohol (PVA). The optimal conditions were experimentally determined and it was found to be initial pH = 3, [H2O2] = 50 mg/L, [Fe0]...

The demands existing at the European Union level impose a new approach of the problems concerning the mining exploitation from the point of view of the effects and pressure exerted by them over the environment and of all the consequences of the socioeconomic development. Starting from the strategic objectives imposed by the European programmes at the environment-protection level, corroborated with the rather slow rhythm of reform of the Romanian mining industry determined by the delay concerning the achievement, i...
