Indicators sensitivity analysis for environmental engineering geological patterns caused by underground coal mining with integrating variable weight theory and improved matter-element extension model

This research utilized the variable weight theory (VWT) and improved the matter-element extension model (MEEM) to conduct an indicators sensitivity analysis of environmental engineering geological patterns (EEGPs) related to underground coal mining. First, four types of EEGPs, i.e., basically unaffected model, gradually restored model after destruction, gradually deteriorated model and disaster model, were defined. Subsequently, 13 indicators...
