Slope stability mining radar in mine slope stability monitoring at open cast mines. It is development on the radar technology, is now being widely used in several countries to provide real time monitoring and advance warning signals before any slope or dump failure in open cast mines.
The paper concluded that a comprehensive slope monitoring program is needed in a big open pit mine with great slope stability challenges. On the other hand, a combination of two or more of the techniques is needed is shallow open cast or open pit mines, where the lifespan of the highwall is short.

Maptek laser-based monitoring solutions allow operations to safely survey pit highwalls and dam walls from remote standoff. Stability analysis can be conducted on high resolution Maptek laser scans and accompanying digital imagery for monitoring risk.
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.

Highwall mining is a method of mining that originated from auger mining. The method differs in that continuous miners, rather than augers, are used to bore an entry adjacent to the coal seam of a highwall left behind in an open pit mine after excavation has been completed.
