This publication presents th e assessment studies of two important characteristics, limiting the utilization of the geological envi ronment for various pu rposes, especially construction. The first is the character of the pre-quaternary bedrock, other is the rock workability. Character of the pre-quaternar y bedrock and its depth is important primarily for the complex foundation engineering. They carry the greater load caused by the weight of the structure itself. Therefore, it is often necessary to carry the weig...

Many researches have been carried out in field of “Roof rock behavior in coal mines", most of them concentrated on mines devel opment networks; but a less attention have been paid to assessment and classification of roof strata behavior over long wall coal mining panels. In this paper, It has been a ttentioned to roof strata behavior over long wall coal mining panels in East Alborz coal mines. Intens ive field work and laboratory analyses that discuses the influence of various parameters on roof rock behavior of t...

THREE VIEWS ON KINEMATIC ANALYSIS OF CRANK MECHANISM IN EDUCATIONAL PROCESS

(Stef92 Technology, 2011-06-20, Šmeringaiová, Anna)

Show more

The article deals with the kinematics analys is of crank mechanism realized by three methods followed by comparison of achieved results. The crank mechanism is the most commonly used mechanism in practice; it is the part of the various machines and almost every car. It belongs to the fundamental mechanisms whereon the kinematic characteristics of mechanism are investigated by students on FMT TU Košice with seat in Prešov within the scope of Technical mechanics lessons. Ar ticle hints as the utilization of suitable...

SENSITIVITY ANALYSIS OF INVESTMENT IN SARBISHEH BASALT-ANDESITE MINE, BIRJAND, USING OF MONT CARLO SIMULATION

(Stef92 Technology, 2011-06-20, Aryafar, Ahmad)

Show more

Investment in the mine scope is one of the most risk able fields. In the new management skills, risk management is a ve ry important feature. During of the execution of a mine project, the variation of each effective factor can affect on the execution, production and efficiency, therefore a mining project ma nager must be knowledge about of any effective parameter such as Annual productivity, annual benefit, annual cost and exploitation time, in project The net present value (NPV) is one of the most important meth...

NEW PLANT TAKSONS FOR THE REPUBLIC OF KOSOVA

(Stef92 Technology, 2011-06-20, Millaku, Fadil)

Show more

During the research of flora and vegetation of Sharri Mountains we have found five new taxons for Kosovo’s flora. As part of the Sharri Mountains we have also researched Mushtisht Mountain which occupied the northeas tern part of the Sharri Mountains and range in altitude 480 - 2092 m (Maja Pashallare). These terrains are rich with rare endemic and relict species to the Balkans and that species have been preserved very well especially at the valley of the Rusenica. During research the Mushtisht Mountain flora’s, w...

A STUDY OF WET DEPOSITION FLUX USING THE SEQUENTIAL SAMPLING TECHNIQUE

(Stef92 Technology, 2011-06-20, O. Akkoyunlu)

Show more

The influence of washout scavenging on the removal processes of SO 4 2-, NO3 - and Cl - ions were investigated using sequential ra in sampling. For this purpose this study investigates the variation of these ions in precipitation using the sequential rain sampling and relationships of the wet depos ition flux to the rain intensity and ion concentration were introduced. We carried out sequential rain sampling for five different rain events sampled in Istanbul on a) March 14 th, 2008 b) March 20 th, 2008 c) March 25...

THE NEW LA-ICP-MS LAB FACILITY IN THE GEOLOGICAL INSTITUTE AT BULGARIAN ACADEMY OF SCIENCES - FIRST RESULTS FROM TRACE ELEMENTS DETERMINATION AND U-PB AGE DATING OF METAMORPHIC ROCKS

(Stef92 Technology, 2011-06-20, Ganev, Valentin)

Show more

The new lab facility at the Ge ological Institute of the Bu lgarian Academy of Sciences was set up in the end of 2009. The main equipment consist a state of the art PerkinElmer ELAN DRC-e ICP-MS and New Wave Research UP-193FX excimer laser ablation system. Combined together, it is a precise instrument for geochemical research and geochronology. One of the leading research topics is quantitative determination of trace and ultra trace elements in rocks together w ith their age dating clar ification. We report our fi...
