Exploration and Mining
The Valea Jiului coal basin is the largest mining basin in Romania and includes from east to west the mining fields: Lonea, Lonea-Pilier, Petrila-Sud, Petrila, Livezeni, Salatruc, Dalja, Iscroni, Aninoasa, Vulcan, Paroseni, Lupeni , Lupeni-Sud, Barbateni, Uricani, Valea de Brazi and Campu lui Neag.
The first opening works in the Lonea perimeter began with the excavation of the Rascoala gallery, in 1870, a gallery supported by brickwork. Also in the same period, the up-to-date exploitation of the outcrops from the Jiet Valley area and the neighboring valleys is proposed.
The general ventilation of the Lonea mine is ascending under the influence of the general depression created by the three main ventilation stations. The analysis performed on the Lonea mine ventilation network leads to the conclusion that the mine ventilation network is particularly complex, a complexity amplified by the large number of air control and regulation constructions.
In order to evaluate in perspective the influence of the changes that will occur in the ventilation network of the mine regarding the distribution of air currents both in size and in the direction of their flow, of the locations of the constructions for directing and regulating air flows, as well as the types of ventilation mining constructions that are necessary for the desired distribution, modeling and simulation programs were used that allow the option of visualizing the network in three and two-dimensional system, for the representation of the ventilation network of the Lonea mine.
This paper presents the analysis of the complex ventilation network of the Lonea Mine with the help of specialized programs.
