Airflow stability and diagonal mine ventilation system optimization: a case study
(2018-09-01)
Article
Accés obertAirflow reverse is a severe problem in an underground ventilation system. In addition, the airflow stability and safety production can be seriously affected by the problem of air velocity overrun in the roadways. In this ... -
Analysis of a historical accident in a Spanish coal mine
(2019-09-26)
Article
Accés obertThere has been a long history of coal mine accidents and these, usually, involve serious injuries, fatalities, and the destruction of facilities. In the seventies, an explosion killed 28 miners in a Spanish coal mine. This ... -
Analysis of the fire propagation in a sublevel coal mine
(2020-07-21)
Article
Accés obertA fire has been analyzed in a real underground coal mine, using a sublevel method, duringan entire year. The study was focused on the collapsed area, reproducing a real mixture formed bycoal, waste, and air gap. The analysis ... -

Creació d'eines per a la gestió de la ventilació en ArcGIS
(Universitat Politècnica de Catalunya, 2016-01)
Projecte Final de Màster Oficial
Accés obertLa funció principal del sistema de ventilació en una activitat subterrània és la proveir d’aire fresc les zones necessàries, i així diluir els gasos nocius, regular la temperatura i assegurar unes condicions bones de ... -
Friction factors determination and comparison in potash mines
(2015)
Text en actes de congrés
Accés obertFriction factor is a crucial parameter for assessing and modelling the ventilation system in underground mining. However, the development of a mine along its life can complicate the airflow supply required to the working ... -

Mine fire behavior under different ventilation conditions: real-scale tests and CFD modeling
(Multidisciplinary Digital Publishing Institute, 2020-05-13)
Article
Accés obertFires in underground spaces are especially relevant due to their potential mortality. However, there is not much research in real-scale spaces done so far. In this study, several fire scenarios were analyzed in an underground ... -
Some approaches to improve the ventilation system in underground potash mines
(Universitat Politècnica de Catalunya, 2016-04-25)
Tesi
Accés obertMine ventilation is a crucial factor for the sake of underground operations. Not only does it affect efficiency and effectiveness rates, but it also influence the health and safety of the employees. Despite it is a topic ... -
Temperature prediction model in the main ventilation system of an underground mine
(Multidisciplinary Digital Publishing Institute, 2020-10-16)
Article
Accés obertA model to forecast the underground temperature in a mine ventilation circuit was developed on the basis of a case study and actual data describing temperature, airflow, and drift length collected over several years. A ... -
