Highwall Hazard Awareness And Risk Assessment

Top Of The Pit Highwalls If the geological formation permits, pre-splitting should be made a part of the mining method for final walls to reduce the potential for loose rock along the face. If a quarry has an exceptionally high face height, and if pre-splitting is a viable option, consider pre-splitting every shot. This is a

Highwall Concerns : Pit & Quarry

Jun 09, 2015 As mining advances, it is imperative that this monitoring system be relocated to those areas of concern. There is a growing trend for radar monitoring systems at mine sites to identify specific areas of instability along highwalls, waste dumps and tailing dams. Wall failures do not occur without warning if the failed area is being well monitored.
