BH2 & BH3 BLOCKHOLERS

The MacLean Advantage:

Rugged and reliable, the MacLean BH2 & BH3 Blockholers are designed to eliminate ore flow blockages and release trapped reserves in draw points and beyond draw point brows without endangering mine workers. Integrated Radio-Remote Control (RRC) allows tramming, drilling and blasting operations to be conducted from safe distances.

Benefits

  • Oversize is fragmented at source, minimizing draw point damage and ore flow
  • Productivity improvements by elimination of non-productive boulder re-handling
  • Boom configuration enables multiple boulders to be drilled from one set up
  • With RRC system, can drill and charge hang ups and operator never exposed to the risks of rock fall
  • Provides auxiliary drilling capability for service holes and rock bolting

Features

  • Fully self-contained drilling system; no air or water services necessary
  • Optional radio and video system designed for underground environment
  • Hydraulic rock drilling
  • Heavy duty frame construction
  • Four wheel drive carrier
  • Reliable, proven power train components

Applications

  • Any underground mine where bulk mining activities generate boulders too large to move, carry, drop through grizzlies or dump into crushers
  • Most effective where multiple draw points allow ore extraction to continue while block hole operations are conducted
