Description
Compressed air is a very important source of power in nearly all mines. In fact, no real substitute has been found for compressed air as a source of power for drilling holes for blasting in underground mining. Moreover, compressed air is used for many other purposes in and around the mine. Mucking machines, scraper-hoists, and ventilation fans are but a few of the machines commonly operated by compressed air. In most mines compressed air is supplied by one or more compressors and delivered to the drilling machines at the working face through a distribution system of pipes and hoses. What happens to the compressed air as it passes through the distribution system on its way to the drilling machine is rarely determined by the small mine operator; he rarely knows whether or not the compressed air arrives at the machine under the pressure recommended by the drilling machine manufacturer. Instead, he tends to be satisfied if the drilling machine will drill a hole. 32 p.
