With climate change, more intense weather phenomena can be expected, including pressure drops related to the arrival of an atmospheric front. Such drops of pressure are the main reason for gas emissions from closed mines to the surface, and a closed,

THE APPLICATION OF A JET FAN FOR THE CONTROL OF AIR AND METHANE STREAMS MIXING AT THE EXCAVATIONS CROSS – THE RESULTS OF NUMERICAL SIMULATION

Autor: Paweł WRONA, Zenon RÓŻAŃSKI, Grzegorz PACH, Lech DOMAGAŁA

Publikováno v: Management Systems in Production Engineering, Vol 23, Iss 3, Pp 156-162 (2016)

The paper presents the results of numerical simulations into the distribution of methane concentration at the intersec-tion of two excavations with a fan (turned on) giving the air stream to the area of the crossing. Assumed case represents emergency

Reversal Ventilation as a Method of Fire Hazard Mitigation in the Mines

Autor: Grzegorz Pach, Zenon Różański, Paweł Wrona, Adam Niewiadomski, Pavel Zapletal, Václav Zubíček

Publikováno v: Energies, Vol 13, Iss 7, p 1755 (2020)

Reversal ventilation is one of prevention methods against fire hazard in underground mines, but it is not recommended for the mines where methane is present. The authors introduce the new method of reversal and by conducting numerical simulations the

Influence of the auxiliary air-duct outlet and the brattice location on the methane hazard-numerical simulations

Autor: Pavel Zapletal, Grzegorz Pach, Zenon Różański, Dariusz Musioł, Paweł Wrona, Adam Niewiadomski, Marian Sofranko

Publikováno v: Energies; Volume 15; Issue 10; Pages: 3672

The article presents the results of research into the influence of the location of auxiliary ventilation devices on the distribution of methane concentrations at the outlet of the longwall in an underground mine. Since this area is crucial from the p
