· One of the most important aspects of mining is selecting a mining method. It determines the efficiency of the economy, technology, and the environment. As shown in Fig. 4.5, mining technique selection is seen as an issue with multiple decision-makers. In reality, some mines exclusively use one type of mining.

There are many guidelines and frameworks for mine closure and reclamation, but the great majority are based on processes – the ‘means’ rather than the ‘ends’, which are outcomes such as future use, performance and function. Success is often judged in the very short term, or is judged post-facto, with hindsight.
