The uncertainty propagation model in mineral resources predication
矿产预测评价中不确定性传播模型

Mineral resource prediction and assessment (MRPA) is a systemic project, which consists of collecting data, extracting information, integrating information, and so on, in which each stage contains some uncertainty due to the variability and complexity of geological objects and the incompletely of human knowledge, and the uncertainty in previous stage can be transferred to the subsequent stage, resulting in that the results of MRPA have high uncertainty. In this paper, the main sources of uncertainty are investigated and on expression model and the propagation model of the uncertainty are constructed.
