Proactive Controls for Highwall Stability

Highwall instability, and sometimes referred to as ground failures, historically are a consistent contributor of mine injuries and fatalities within surface mines. To combat this several efforts, including those from NIOSH (CDC), to educate the mining community with insightful literature focused on hazard recognition and advances in ground monitoring systems have been performed. The question is can more be done or is this our last line of defense to manage potential dangers? Is there a more effective method to reduce hazards presented by ground failures including rockfalls?
