  • Methods of and apparatus for winning reef
    Patent number: 4071095
    Abstract: A reef winning machine comprises a frame on which is mounted a saddle. The saddle carries a boom on which is mounted a drill. The saddle also carries a member on which is carried a mechanical rock splitter. The drill and rock splitter operate simultaneously, the latter acting in a hole that had previously been drilled by the rock drill. A jack moves the saddle along the frame in steps that are the same as the distance between the drill and rock splitter. An impact breaker may be used instead of a rock splitter.
