Two major series of crosscutting dikes (Dk1a and Dk1b) are common in Sungun porphyry deposit. Those are varying compositionally from quartz monzo-diorite to granodiorite. About thirty percent of the sungun stock is filled by Dk1a and Dk1b dikes. Presence of dikes will cause lots of errors in copper content estimation, so determination of dikes is very important. Ten percent of dikes volume could be identified through drawing strings and correlation between boreholes. For estimating and determining the other part o...

Shear flocculation characteristics of magnesite with sodium oleate as anionic surfactant have been investigated in this study. The effects of various parameters such as pH, stirring speed and concentration of sodium oleate on the shear flocculation of magnesite were determined. It was found that the shear flocculation of magnesite was not affected much by the pH changes of the suspension. However, the flocculation of magnesite showed strong dependences on stirring speed and surfactant concentration. By evaluation ...

The First step in analysis of slope stability in open pit mines is punctual definition of rock mass characteristics. Several rock mass classification systems have been presented so far in the area of geomechanics. One of the most widely used rock mass classification systems are the geomechanics classification (RMR) by Bieniawiski. The RMR classification is based on the definition of classic membership functions. So characterization of rock masses and determination of their strength may involve some uncertainties d...

In the detailed exploration and reserve estimation, with separating the alteration (as the controller of the grade) in ore reserve and estimating the reserve in each alteration, the estimation variance will decrease and the accuracy of the estimation will increase. This paper tries to quantify and separate the alterations using discriminant analysis, a multivariate statistical method, and distribute them through sequential gaussian simulation in the Sungun copper deposit. A simple linear discriminant function tran...

The uniaxial compressive strength (UCS) is one of the important input parameters used in rock engineering designs of underground spaces, or rock blasting, drilling, slope stability, excavation rate and many other civil and mining operations. Although, the method is relatively simple, it is time consuming and expensive; also, it requires well prepared rock cores. Therefore, indirect tests are often used to predict the UCS, such as Schmidt hammer, point load index and sound velocity. Besides, these indirect tests ca...

In this case will be easy to take preventive actions with regards to procetions workers health.

Sediment transport rates are a function of flow hydraulics, bed composition, and upstream sediment supply. Open-channel flow problems are relatively more difficult to solve than those of closed-conduit because the shape and size of a natural channel vary in a wide range from rivulets to large rivers. While the artificial (manmade) channel has a regular geometric shape, the cross-sectional shape of natural channels may be very irregular. In a movable boundary channel the cross section undergoes deformation due to s...

Implication of interaction matrix was realized here at private company owned underground coal mine. After clear description of the interaction matrix and its properties, selected mine workers and engineers worked at the studied underground mine were asked to evaluate predefined 21 evaluation parameters. During the evaluation of the matrix, the parameters were evaluated to obtain critical ...

In the detailed exploration and reserve estimation, with separating the alteration (as the controller of the grade) in ore reserve and estimating the reserve in each alteration, the estimation variance will decrease and the accuracy of the estimation will increase. In the other hand without any additional drilling, it is also possible to decrease the estimation variance by lowering the sill of variograms. In this method, we have categorized the data into different lithologies and different alterations such as skar...

Nowadays the importance of brown coal as a raw material is caused by growing needs of power in the Czech Republic. It namely concerns the only major domestic fossil raw material without which our country would become fully depended on the import of energy resources. Over 70\% brown coal reserves have been exploited in the North- Bohemian Basin today. Opencast mining of brown coal naturally led to vast landscape damages. Therefore reclamation work has acquired great significance. Brown coal is mined in four general...

Defining the mineral potential of the sea floor could be handled by different methods, but the prerequisites for each methods is to clear the conditions of precipitation environment such as physico – chemical conditions and also it depends on the type of precipitant. The appearance of any mineral in the sea floor strongly depends on the aqueous environment and the physical prosperities of the mineral. In this article, first of all, I considered the physiographic regions of the sea floor in entire the world, an a...

The southern edge of Eastern Pontids is covered by rock units belonging to two distinct continental crusts that reunited through a Late Upper Cretaceous-Eocene suture zone. In the north of the Suture zone (Olur), Paleozoic aged acid magmatits (Permo- Carboniferous) constitute the continental crust basement. On this basement, there is uninterrupted marine sediment which has disconformably developed between Upper- Lias Late Cretaceous. These sediments have deposited under the conditions of Lias- Lower Malm basic vol...

The construction boom along the Black Sea coast in Bulgaria made the contractors to seek sites near to precipices and landslide areas. Under these extreme geotechnical conditions, the construction has three basic aspects: 1/ Stability of slopes should be durably guaranteed; 2/ The connection between the leisure zone and the sea should be optimally designed, and 3/ The safety of people at the beach should be secured. A complex structural approach is necessary in order for the problems to be solved. It should includ...

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...
