Sistem de control al nivelului lichidelor in cadrul C.N.H. Petrosani - Liquid Level Control System for The N.C.H. Petrosani
The continuous level control of water and other technological liquids, is of great importance both from a continuous technological process inside mining exploitations point of view, measuring the level of the collector reservoirs and pumps aspiration pit, inside of cesspools of pits and inside eventual pit digging, and from work security point of view.

Timpul - factor important in procesul de deplasare si deformare a suprafetei terestre sub influenta exploatarilor subterane - The Time - An Important Element in Shifting and Deformation Process of The Terrestrial Surface under The Influence of Underground Exploitations
As a result of the underground exploitation of the useful mineral substance deposits the movement of the roof rocks is produced, affecting the integrity of the surface land. The size of the surface's degradation and the rock's movement character are influenced mainly by a number of factors. Depending on them, the rocks' ruination phenomena under the influence of the exploited space can transmit or not to the surface.

Contributii la elaborarea unor metode moderne de analiza si evaluare a riscurilor profesionale (I) - Contributions at The elaboration of Some Modern Methods of Analysis and Evaluation of Occupational Risks (I)
The evaluation of the occupational risk represents an operation whose purpose is to evaluate (assess) the risk for accidents and occupational diseases which can occur during the development of some hazards produced by human activities inside the working system, with the view to giving a qualitative and a quantitative size of this element.

Influenta Haldei de steril Valea Stiucani asupra dinamicii locale a reliefului (I) - The Influence of Stiucani Valley Sterile Waste Over The Local Dynamic of The Relief (I)
The Stiucani sterile rocks waste is overlaied on a small steep valley from north of plateau. In this paperwork we propose to analyse the influence of natural morfology and geomorphology processes about the dynamic of this waste. We mapped, on eary maps (from 1969), at detailed scale, all geomorphologycal processes from the area, and compared this product with the actual situation of processes occured on the waste.
