HORIZONS OF COOPERATION GERMAN MINERS AND THE CAUCASUS

Shubin N.E., Drebenshtedt K., Golik V.I., Gabaraev O.Z.

Article is devoted to the search for new areas of training mining. The system of coordination of training activities at the international level with the Technical University of Freiberg Mining Academy. Dana note on the history of mining in Germany and in the North Caucasus and the development of cooperation between German and Russian miners. Noted that the activities of TU PHA and SKGTU coincide , which confirms the possibility and expediency of their mutual agreement. Concluded that mutually beneficial cooperation at the international level between an element of the policy of the University to increase the level of training.

WAYS OF ENSURING A FAVORABLE ECOLOGICAL AND HYDROGEOLOGICAL REGIME IN THE COAL-MINING REGIONS

Sadovenko I.O., Inkin O.V.

On the basis of comprehensive studies substantiated technology stabilizing influence on the dominant physical and chemical processes, accompanied maintainer underground mining of coal within the mine field. By experimental and theoretical investigations have revealed regularities change the solid and liquid phases of coal-bearing strata in the process of their movement in the technological chain: coal-bearing rock - mine dump (land reclamation) - absorbing complex deposits in blood - flow in a mine and a natural watercourse. The dependence linking the appearance of anomalies in the concentrations of the chemical components of the order mining blocks mine field and the reclamation.

OPTIMIZATION OF THE AUTOMATIC GRAB SAMPLING AND PREPARATION FOR CONVEYING OF THE AVERAGED SAMPLE FOR ANALYSIS

Khmara V.V., Lobotsky Yu.G.

The paper dwells on the current status and main requirements for the automatic instrumental sampling of representative samples of flotation pulp during the automatic sampling of products at concentrating mills. It discusses the specific design features and the operating principle of the automatic sampler from the descending parts of the conveying pipes. It is noted that to optimize the process of the representative averaged sample composition from a set of sequential grab samples it is necessary to compress each grab sample proportionally using a special equipment. The paper also describes the main requirements, design and operating principles of the universal device for the automatic compression of the flotation pulp grab sample.

OPTIMIZATION OF VERTICAL TYPE CENTRIFUGAL MILLS DESIGN AND MODES OF THEIR OPERATION

Khetagurov V.N., Kamenetsky E.S., Minasyan D.G.

It is shown that the optimization of the vertical type centrifugal mill design is expediently carried out by computer simulation. Examples provided where such modeling has greatly improved parameters centrifugal mill. The design of the mill complex further improved are encouraged to consider the impact a number of input parameters , such as rotor speed, number and shape of the edges of the rotor, pole height of the material in the mill housing and their relationship with the output parameters which allow to design the mill with the specified characteristics.
