Jul 31, 2019Pit. The dominant feature in an open pit or quarry operation is the "pit," a broad, deepened, often funnel-shaped area where material extraction and other active mining activities take place. The pit is created when the overburden, the rock or soil overlaying a deposit of minerals or stone, has been removed to access the material being mined.

Several 3-D models were constructed of both the entire pit and of the individual highwalls. The quarry pit models were used to track the mining progress to show newly formed interior highwalls (Figure 6 and Figure 7). Our geologic interpretation of the highwalls was based on our experience of mapping these same units in previous research [4,9

Blasting near open pit walls

Abstract: The topic of blasting near pit walls is one that invokes mixed reactions from different mining departments. For many mine operations and mine scheduling departments, it often represents a significant disruption to efficient work flow, while to geotechnical departments it represents a critical component in the task of delivering safe and competent pit walls and compliance with pit

PREVENTION OF ACID MINE DRAINAGE GENERATION FROM OPEN

Exposed, open pit mine highwalls contribute significantly to the production of acid mine drainage (AMD) thus causing environmental concerns upon closure of an operating mine. Available information on the generation of AMD from open-pit mine highwalls is very limited. Most likely, this is due to the difficulty and danger of physically working on or near the face of the highwall.
