 · Blast Design: This is meant to be a toolbox for blast design in conventional rock quarrying and open pit mines. This write-up is not meant to give straight answers to the blast design parameters, as every single quarry is unique. However, the general relations between the main blasting parameters; geology, blastability and explosives, will be.

and waste materials. Furthermore, the geometrical characteristics, used to design and optimise the pit, are highly relevant to the project's economics and safety, as they are associated with acceptable design criteria, which determine the stability of the open pit's walls. Among these characteristics are bench.

17* Open Pit Optimization

ABSTRACT: The open pit design and scheduling problem is a large-scale optimization problem that has attracted considerable attention during the last 40 years The development of the "know-how" to improve economics of open pit mining projects through the use of mathematical optimization techniques goes back to early 's.

GEOTECHNICAL CONSIDERATIONS IN OPEN PIT MINES

The design of open pit excavations will endeavour to prevent hazardous and unexpected failures of the rock mass* during the operating life* of the open pit. The importance of a systematic approach to mine planning and design using soundly based geotechnical engineering methods cannot be over-emphasised. Open pit mines can.

Calculation and design of slip roads in different configurations, starting from the specified point in the open pit edge, as well as creating names for slip roads elements.

Open Pit Mine Planning and Design

 · Open Pit Mine Planning and Design: Step two. Produce a solid wireframe of the pit. The pit shell solid represents the shape and volume of material that will be excavated throughout the life of mine. At this stage, Interactive Wireframe Boolean can be used to boolean the pit DTM against a topographic surface to create a pit shell solid.
