toward the pit. Since this displacement cannot be detected from the pit floor, it is extremely important to frequently inspect the crests of highwalls above active work sites. Safe access should be maintained at all times to the regions immediately above the active mining. Frequent inspections may be necessary during periods of
Assessing and Monitoring Open Pit Mine Highwalls. This paper introduces various warning signs of slope instability so operators are better able to recognize hazards. The most common slope monitoring equipment and practical methods of installation are discussed as well as the limitations of these systems.

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.

Many of the current monitoring methods are also difficult to implement at mines where steep highwalls and lack of benches limit access to areas above the working floor. In addition, as mining progresses, it is necessary to monitor different sections of pit walls.

Radar, extensometers, prism monitoring systems and other geotechnical equipment have been used in open pit mines since the early 1990s. These high-tech systems are used to monitor for slope movement within the walls of open pit mines. The real-time data is used by engineers in combination with visual inspections from more than 800 workers trained
Coal mining was initiated at the study site in 1969, and has been ongoing for 31 of the past 35 years, using both underground room and pillar and open pit truck and shovel operations. The surface operations began in 1972. The current operator has been mining on the property since 2004. Open pit geometry is based on highwalls (pit slopes
practice in open pit mines. The application of sound geotechnical engineering practice is considered to be an integral component of Part 2 of the Mines Safety and Inspection Act 1994 (MSIA). It is emphasised that this guideline is not totally inclusive of all factors concerning the application of geotechnical engineering in open pit mining.

nisms. Open-pit mines often require ex-pit pumping to keep water away from the pit walls and ensure a safe and efficient mine. The lack of proper seepage investigation and monitoring can result in a lack of pit-wall stability. We have extensive experience in assessing, modeling, and mitigating groundwater and seepage problems.
