Slope stability in opencast mines and quarries
and slope failures. The best control for protecting people working near faces is a quarry/ mine plan or design that has considered your site's particular geological and geotechnical characteristics. Planning for excavations requires a good understanding of ground conditions and identification of ways to avoid potential ground failure.

Failure Analysis
Root cause failure analysis helps a business get to the source of a product failure. More importantly, it provides the manufacturer with the information needed to address and correct the issue causing the failure. Root cause failure analysis is usually a multidisciplinary process. The tools NTS uses during an analysis include visual inspections ...
The Failure Analysis Process: An Overview
Failure analysis of the physical object is often defined as a part of a larger investigation whose intent is to prevent recurrences. If we are to take the broadest view of what is required to prevent failures, there is one answer that stands out: education. Education needs to happen at multiple levels and on multiple subjects within

Introduction to Failure Analysis and Prevention
The importance and value of failure analysis to safety, reliability, performance, and economy are well documented. For example, the importance of investigating failures is vividly illustrated in the pioneering efforts of the Wright Brothers in developing self-propelled flight. In fact, while Wilbur was traveling in France in 1908, Orville was ...

Plane failure in rock slopes – A review on stability analysis
In rock slopes plane, wedge, toppling and rock fall are common modes of failures ( Tang et al., 2016, Lee and Wang, 2011, Yoon et al., 2002, Hoek and Bray, 1981, Hocking, 1976). Plane mode of failure generally occurs in slope formed by stratified sedimentary and meta-sedimentary rock formations. The plane failure in rock slope …

This method was chosen in the absence of actual traffic data. Using a CBR of 3 percent, pavement thicknesses of 533 mm (21 in.), 610 mm (24 in.), 660 mm (26 in.),
What is FMEA? Failure Mode & Effects Analysis | ASQ
Begun in the 1940s by the U.S. military, failure modes and effects analysis (FMEA) is a step-by-step approach for identifying all possible failures in a design, a manufacturing or assembly process, or a product or service. It is a common process analysis tool. "Failure modes" means the ways, or modes, in which something might fail.
