Permissible Electric Face Equipment and Other Mine Equipment Approved from January 1969-December 1974

摘要

This publication lists permissible mine equipment, except respiratory protective apparatus and explosives, approved by the Bureau of Mines and Mining Enforcement and Safety Administration (MESA) from January 1, 1969, through December 31, 1974, for use in underground coal and gassy noncoal mines. It also lists mobile diesel-powered equipment approved for underground noncoal mines. The Federal Coal Mine Health and Safety Act of 1969, the Federal Metal and Nonmetallic Mine Safety Act and the implementing federal regulations require that only permissible equipment, that is, equipment meeting specifications prescribed by the Secretary of the Interior to assure that such equipment will not cause a mine explosion or fire, may be used in or by the last open crosscut of an underground gassy mine. The purpose of this publication is to inform the public about approved equipment available to comply with these laws and regulations. (ERA citation 08:048553)
