Identification of cost factors relating to mining incidents
By E. P. Preis, R. C. W. Webber-Youngman
The real cost of any mining incident has, empirically, proven to be estimation-driven, rather than factdriven. One of the main reasons for this lies with the complexity of the cost composition of any
