Revista Minelor nr.12/2010 Cuprins Summary Krzysztof KOTWICA, Janusz, RES O nouă soluţie privind utilajele modulare pentru lucrări miniere mecanizate şi prelucrarea locală a mineralelor din cariere A New Solution of Module Unit Machine for Mechanical Mining and Dressing in Local Open Pits The proposal of a pilot project of a module unit machine for mechanical mining and dressing of minerals designed to meet the needs of road engineering and building industry in small local strip mines has been described in the paper. Separately working modules were described as well as the whole machine and operation technology with their application.
Octavian HERBEI Posibilităţi de utilizare a proiecţiilor cartografice Mercator şi U.T.M. în activităţi practice Possibilities for The Use of Mercator and U.T.M. Cartographical Projections in Practice The analyzed projections from this paper are cartographical projections of great importance in practice, solving cartographical problems regarding map drawing based on practical needs. These are the ones referring to terrain surfaces that will be represented, to the accuracy that must be obtained, as well as the ways to accomplish favorable and precise links with other kinds of cartographical projections.
Andrei ROMANESCU, Dragoş PĂSCULESCU Prezentarea şi simularea unei proiecţii homopolare moderne din sistemul energetic naţional Presentation and Simulation of a Modern Homopolar Protection from The National Energy System This paper presents a real study of the operation of a modern homopolar protection for overhead power lines through its analysis and simulation using a specialized software. We will present all possible faults, and will also highlight the need of a homopolar protection on transmission lines and power distribution lines.

Ionuţ PREDOIU Soluţie privind redarea în circuitul economic a haldei de steril Tismana I din cadrul Complexului Energetic Rovinari The Solution for Reinstatement in The Economic Circuit of The Tismana I Dump from The Rovinari Energy System In the present economic environment, marked by ever wider recognition of interdependence between environment and development, there is an increasing environmental demands of society, demands materialized in the regulations becoming more stringent. A particular activity / technology, produces, in addition to the direct
effects which have been designed, a series of indirect effects, some negative for the man and his environment and thus bring into question its actual utility.
Mariana RUDĂREANU Dreptul de servitute reglementat de Legea minelor Easement Right Regulated by The Mining Law Easement is a task which is imposed as a limitation of the exercise of the attributes of the land right by the right holder. By normative acts which regulate a certain field of activity, which is usually exploitation of goods which are the public property of the state, an easement law was instituted with its own configuration, diffe-rent from its treatment established by the Civil Code.
Constantin ŞTEFAN Sistem de conducere operativ “HMI”bazat pe echipamente programabile în industria tratamentelor termice ‘HMI’ Operative Control System based on Programmable Equipments in The Heat Treating Industry The control system is realized by an opened system that allows the subsequent developing (hardware and software) of the process and operator plants as well as the communication system. An operative control is the knowledge and the supervision of the running conditions from the operator panel (HMI) of each equipment without moving in the currently place to ascertain the non-operating equipment [1]. It is known that in the mining exploitation placed on tens and hundreds of hectares, the movement is very hard on the field to establish the nature of fault and what exactly was damaged. These systems come to help these operations by decreasing the time crashes, having the possibility to see forward the fault equipment, being attached on the control or operating panels. HMI - Human Machine Interface; PLC - Programmable Logic controller; VFD - Variable Frequency Drive
