• Description:
  A study was carried out to identify and develop improved techniques to alleviate a major cause of accidents and work stoppages when an oversize rock or boulder lodges in the throat of a crusher. The configurations and operations of various crusher types and sources of boulders in a mining operation are described and a detailed review is made of mining, quarrying, and construction regulations for all states, Canada, and the federal government for applicable provisions. Representative mines were visited and other operations were contacted to determine boulder handling techniques included mudcapping, bombs, and blockholing, often done crudely and inefficiently with poor practices. Various mechanical systems were used such as hooks on overhead cranes, impact hammers, and grapplers. Safety analyses of all methods pointed out the hazards associated with blasting in the open and the dangers of entering a crusher. [Description provided by NIOSH]
