Abstract: | In recent years there has been growing interest in Britain in the possibility of opting for underground, rather than surface, extraction methods for low value aggregates. Such a policy would lead to reduced environmental impact and could, under particular circumstances, offer cost advantages to the producer. An assured supply of aggregates at acceptable cost is essential to any modern industrialised country. There is therefore a need to devise a technique capable of assessing the financial implications of a switch from surface to underground production of aggregates in any region. This paper reports the development of a computerised simulation programme, able to calculate the costs of underground working with sufficient accuracy to facilitate strategic decisions on the merits of more detailed analysis in any area of interest. An example is reported of the use of the programme to evaluate underground stone mining potential in the South East of England. |
