ABSTRACT

Heat and exhaust emissions are representing two of the major health and safety issues
induced by the presence of Diesel-mounted equipments in underground mines. The first
one has greater effects in deep mines, while the second one requires a careful
dimensioning of ventilation airflows in all mines. Taking into consideration the higher
exposure level of Diesel mounted equipment drivers at the noxious products contained
in the exhaust emissions, it clearly appears as a major safety concern the need for an
expeditious method of assessing the pollution degree. The paper presents the legal
requirements regarding the Diesel exhaust emissions in Romanian underground mines, a
new expeditious method aimed at assessing the mine air pollution degree and the results
of measurements and experimental data processing at Baia-Sprie and Şuior mines. The
measurements carried out in two metal mines from Baia Mare basin and the plotting of
individual and cumulated dependence curves, have confirmed the feasibility of using the
CO2 as a control index of pollution levels generated by underground operation of Diesel
mounted equipments.
