Faults in Underground Mining: Issues & Solutions

Surfaces formed as a result of the pressures exerted on each other by rock masses movements on the Earth in a certain direction as “cracks” (joints), and if there is a significant movement of the masses around them, we define these cracks as “faults”.
The movement of blocks that travel a distance laterally and/or vertically relative to each other in 3 dimensions is the term we call as “slip”, “displacement”. As a result, the use of the term “fault” instead of “crack”(joint) is determined by the presence of a “significant” slip, as it is possible to observe a slip of a few centimeters or “hundreds of meters”. Simply put, the amount of slip that will cause you discomfort or anxiety in your mineralization will constitute a “fault” for you.

The term “fault” was first used in the late 18th century by Scottish geologist (physician, natural historian, chemist, agriculturalist) James Hutton (1726–1797), known as the father of “modern geology” in some circles. The word “fault” originated from the Old French word “faute” which meant “opening, gap; failure, flaw, blemish; lack, deficiency” was first used in the late 13th century, thought to be derived from Vulgar Latin word “fallita”.
