Top Soil Technical Project



From  (Technische Universiteit Delft)

Introduction
As an owner of a contracting company, a proposal offer has to be made which gives the best most profitable price per bank cubic meter for a pre-stripping mining operation.
First,  the total volume that has to be excavated is calculated. Then, a plan has to be designed in what order the mine is excavated. Dumping sites and access roads influence the strategy in which the mine is going to be excavated. After this is done, different scenarios using different machinery are designed. Using these scenarios, different costs calculations can be made and a price per bank cubic meter can be offered. With this price, a conclusion can be made on what the best scenario for this project is and therefore the most profitable for the contracting company.

Pillar Design

The Safety Factor (SF) is the pillar strength divided by the pillar load.
Safety Factor = Pillar Strength / Pillar Load
                                    
Pillar Strength – is a function of both a size effect and a shape effect.
1. Size Effect
2. Shape Effect
Size Effect – The average strength decreases as specimen size increases. ....
