摘要

Most of the federal safety and health legislation has followed major mining disasters that received significant public attention. * Federal organizations - This bar shows federal agencies established to deal with mining safety and health problems and some of the organizational changes that have occurred. * Significant safety and health advancements-This section includes notable achievements in mine health and safety technology. Some of the highlights of the Bureau's work in its first five years included: * The demonstration that coal dust greatly increased the magnitude of mine explosions over those involving methane alone.n It has demonstrated an eight-hour time weighted average exposure reduction of 3 dB(A).The urethane coating also extends chain life by preventing chain link failures.
