Regulations
The volume (expressed in cubic feet per minute or cubic meters per second) of air required to ventilate an underground mine is determined by mining- or geotechnical-engineers. It may also be regulated by the local governing body. However in some developing countries the mandated ventilation requirement may be insufficient, and the mining company may have to increase the ventilation flow, in particular where ventilation may be required to cool the ambient temperature in a deep hot mine. One method to arrange ventilation is to place huge burner on the bottom of the vertical hole. Heated air rises up and the replacing air brings fresh air to the mine.

Famous quotes containing the word regulations:
“If the veil were withdrawn from the sanctuary of domestic life, and man could look upon the fear, the loathing, the detestations which his tyranny and reckless gratification of self has caused to take the place of confiding love, which placed a woman in his power, he would shudder at the hideous wrong of the present regulations of the domestic abode.”
—Lydia Jane Pierson, U.S. women’s rights activist and corresponding editor of The Woman’s Advocate. The Woman’s Advocate, represented in The Lily, pp. 117-8 (1855-1858 or 1860)
“If it were possible to make an accurate calculation of the evils which police regulations occasion, and of those which they prevent, the number of the former would, in all cases, exceed that of the latter.”
—Karl Wilhelm Von Humboldt (1767–1835)
“The admission of Oriental immigrants who cannot be amalgamated with our people has been made the subject either of prohibitory clauses in our treaties and statutes or of strict administrative regulations secured by diplomatic negotiations. I sincerely hope that we may continue to minimize the evils likely to arise from such immigration without unnecessary friction and by mutual concessions between self-respecting governments.”
—William Howard Taft (1857–1930)
