Investigation on fire potential of ventilation ducts

Autor: Ankit Jha, Vinod Amar, Purushotham Tukkaraja

Publikováno v: Journal of Sustainable Mining, Vol 18, Iss 4, Pp 270-276 (2019)

Fires in underground mines can create dangerous conditions for personnel and cause severe damage to property. Because of the confined nature of the underground environment, these effects can escalate rapidly. In underground mines, air ducts/bags are

Numerical investigation of the effectiveness of radon control measures in cave mines

Autor: Kayode Ajayi, Khosro Shahbazi, Purushotham Tukkaraja, Kurt Katzenstein

Publikováno v: International Journal of Mining Science and Technology, Vol 29, Iss 3, Pp 469-475 (2019)

Ventilation is one of the radon control measures in an underground working environment. However, the dynamics related to the cave mining methods particularly in block/panel cave mines, complicate the design of effective ventilation system, and implem
