彬长矿区合理采煤方法选择的数学评价

摘要

以彬长矿区4＃煤层为工程实例，根据采矿工艺理论与矿井实际地质情况，对（特）大型矿井的具体情况应用定性与定量相结合的层次分析法对各影响因素进行了阐述和分析，最终建立了（特）大型矿井开采方法选择评价方法，为（特）大型矿井开采方法的确定提供了科学的依据，对特大型矿井可持续发展具有重要的指导意义和参考价值。%Taking №4 coal seam of Binchang mining area as engineering example , based on the mining technology theory and mine geological condition , the factors influencing ( ultra ) large-scale mine construction were analyzed by using the method of Analytic Hierarchy Process , and the evaluation method of selecting rational mining method of (ultra) large-scale mine was proposed .The research can provide scientific basis for determining the mining method in ( ultra) large-scale mine and has important guiding significance and reference value for the sustainable development of ultra large -scale mine.
