Dezvoltarea durabila si inchiderea minelor - Lasting Development and Mines Closure

ABSTRACT: The good practice in mines closure show that the closing and ecologization works performed without considering its durability involve the State to make additional expenses to remove/decrease the impact on the environment and lasting development of local communities on medium and long term.

Posibilitati de valorificare integrala a slamului steril rezultat in urma procesarii carbunilor din Valea Jiului in vederea reducerii impactului asupra mediului - Possibilities of Valorification of Slutge Resulted in The Coal Processing in Jiu Valley The View to Reduce The Impact on The Environment

The paper present the research done to attempt an entire valorification of the slutge resulted in the coal processing plant from Jiu Valley. These waste which represent about 5 milions tones is a potential souces of combustible mass. Also this waste can be use in builiding materials industry and to producing ecological bricks.

Utilizarea tehnologiei de inertizare cu azot in Europa - The Implementation of Inertization with Nitrogen Technology in Europe

The procedure of inertization with nitrogen was applied for the first time in Czech Republic in 1949; nevertheless, Germany implemented this procedure at industrial scale in 1974. This procedure was implemented with significant results in several European mine fields. This paper shows the manner used for the implementation of this inertization procedure in several European countries.

Impactul carierei Rosia de Jiu asupra dinamicii locale a reliefului - The Impact of Rosia de Jiu Open Pit on Local Dinamic of Relief

The open pit mine Rosia de Jiu is located into the flood plain of the river Jiu and it is extending on the river terraces and slopes. It is one of the largest open mines from Romania with a width of 2,75 kilometers and a length of about 4 kilometers. We proposed to analyse the influence of human activities about the changed of the relief from this area; and this in two ways, directly through activity of excarating and indirectly by geomorphological processes induced of this kind of activities like landslides, rock fall, mud flow, subsidence.

Particularitati structurale si functionale ale sistemelor de ungere centralizata ale excavatoarelor cu rotor - Structural and Functional Features of Centralised Lubrification Systems at Rotor Excavators

For the lubrication with fluid and dense lubricants, centralized semi-automated and automated lubrication systems allow to settle some of the most difficult problems that might occur in the current practice of lubrication. This paper shows the specific features of these category of systems that produce lubrication of the rotating and translating moving bodies and mechanisms belonging to the rotor excavators, important components for a flawless operation of the equipment.

Moduri de abordare a disponibilitatii morilor cu bile - Means to Approach The Availability of Ball Mills

The paper presents means to study the availability of ball mills and the manner of results interpretation, either based on real observations, but limited on time, or by stimulation of such equipments surviving. Regardless of manner of study, the conclusions turn to same solutions to increase the availability.
