CDC - Mining Topic - Ventilation Overview - NIOSH

02/06/2020  NIOSH Mining developed models to predict methane emissions at underground coal mines and the effects of various methane drainage techniques on emission rates. In addition, ventilation models were used to investigate the effects of larger panels and increased production rates on bleeder ventilation system designs to control methane accumulations on the longwall face and at the tailgate

Chapter 1: Mine Ventilation – An Overview

Revolution brought a rapid increase in the demand for coal. Conditions in many coal mines were quite horrific for the men, women, and children who were employed in them during the eighteenth and nineteenth centuries. Ventilation was induced either by purely natural effects, stagnating when air temperatures on the surface and underground were near equal, or by fire. The first ventilating ...

Underground Mine Ventilation Technical Aspects of

In coal mines, relatively small methane explosions sometimes cause much larger explosions of coal dust which cause most of the fatalities and damage. Methane gas is sometimes present in quantities which make it economical to extract the gas itself before “mining,” through boreholes. This is called coal-bed methane. Coal can then be mined later under safe conditions. In coal and fiery mines ...

Underground mine ventilation - Wikipedia

Underground mine ventilation provides a flow of air to the underground workings of a mine of sufficient volume to dilute and remove dust and noxious gases (typically NO x, SO 2, methane, CO 2 and CO) and to regulate temperature.The source of these gases are equipment that runs on diesel engines, blasting with explosives, and the orebody itself. The largest component of the operating cost for ...

DANGERS OF COAL MINING - Coal Mining

Gas explosions in coal mines happen because of a build up of methane gas. This is why good ventilation in mines in so important. Without good ventilation the mine would explode. Gas levels have to be monitored at all times, and if the mine is not ventilated or to over ventilated all miners must be evacuated. Tools that are used in mines also have to be closely monitored because if the tool ...
