Research on Optimal Evaluation of Coal Pressing Under Buildings Filling Mining Scheme
The traditional coal pressing under buildings mining scheme is mainly determined by engineering analogy method,and the selection of the scheme lacks scientific rationality.In order to achieve the convenient and optimal selection purpose of the coal pressing under buildings filling mining scheme,based on the related theory of multi-attribute decision-making,research is conducted around the evaluation indicator system and evaluation model applicable to coal pressing under buildings filling mining.A multi-attribute evaluation indicator system considering three aspects of economic,technological,and safety is constructed;The traditional grey target decision-making model is improved from the perspectives of index weights and bull's-eye distance angle,and a game theory combination weighting improved grey target decision-making model is established.Taking the coal pressing under buildings mining in the fifth mining area of Tangkou Coal Mine as an example for model evaluation and inspection,the evaluation results show that the optimized scheme of this model is consistent with the actual adopted scheme of the mine,the economic benefits generated by applying this scheme are 189.531 6 million yuan,and the damage level of surface buildings is controlled within the damage range of level I.The mining economy and safety are the best,which indicates that the evaluation indicator system and evaluation model constructed in this article can reasonably and effectively op-timize the coal pressing under buildings filling mining scheme.
