Skip conveying system for underground mine - has pendulum mounted top skip chamber in filler opening of bottom one

摘要

The conveying system has the load space of the skip divided into several chambers one above the other. The top chamber comprises a pendulum-mounted open-top vessel (4) with a bottom flap (5) which can be opened and shut, situated in the filler opening (6) of the bottom chamber (7). The top vessel can be arranged to swing clear, to allow filling of the bottom one, as it is equipped with a lug for attachment of a tilting mechanism. The design allows the system to be used both for conveying the coal etc. to the surface and for returning slag underground for backfilling.
