Abstract

Modern mining industries focus on system efficiency much more than before. Simulation programs for ventilation networks and thermal environments are gaining momentum. However, it is difficult to achieve correct results for thermal environments through simulation programs. One of the reasons for this is the inaccurate estimation of heat from blind headings. In blind headings, the heat transferred from fragmented rock, explosives anddiesel equipment to the air could make the thermal environments much more complex. In order to verify the heat load, in situ measurements were carried out in Hishikari Mine. According to the air temperature variation with time, a new method for determining the heat load from fragmented rock and explosives is introduced in this paper. The heat from diesel equipment is also discussed. The theoretical calculation results showed good correlation with in situ measurements.
