Application of GIS-based decision-making model to evaluate safety of underground mining under Neogene aquifers

This paper presents a decision-making model to evaluate the safety of underground coal mining under the Neogene aquifers which are composed of sand based on geographic information system and entropy values. An evaluation index system, which contains the main factors that determine the safety of underground mining under the Neogene aquifers is proposed by considering the geological and hydrogeological conditions. Then, the thematic maps of the...
