Research on the economic design of mine ventilation system

The basic ventilation equation of power equal a constant times quantity to the power three (P=constant x quantity(3)) makes it an extremely costly palliative as a long term measure. Provision of increased airflow is also limited by maximum tolerable levels of air velocity, the effect upon respirable dust and, in case of coal mines, spontaneous combustion. The paper high lights amelioration measures for climatic improvements at a lower cost. The paper has also shown a method for monitoring air pollution using laser technology.
