针对华北型煤田下组煤底板突水脆弱性问题，在综合分析煤层底板突水危险性影响因素的基础上，考虑到影响底板突水因素的多面性和不确定性，建立了煤层底板突水脆弱性总体评价指标体系。以山西紫金煤业11号煤层为例，运用基于改进AHP （三标度）的模糊综合评价法，对煤层底板突水的脆弱性进行了综合评价。评价结果为：从井田中部向东西两侧，底板突水脆弱性依次为中等、较脆弱、脆弱、中等。评价结果合理可靠，为下组煤开采过程中奥灰水的防治提供科学依据。

For floor water burst problem in down-coal of North China coalfield , considering multiformity and nondeterminacy of influ-encing floor water burst , floor vulnerability evaluation index system of water burst was set up on the basis of analyzing influence factors of floor water burst.Taking 11 Coal-seam of Shanxi Zijin Coal Industry as an example , applying modified AHP fuzzy comprehensive e-valuation method , floor vulnerability of water burst was evaluated.results showed that from middle part of coal-field to east and west side, the vulnerability of floor water burst were respectively medium , weaker, weak and medium.Evaluation result was reliable and this provided scientific reference for Ordovician limestone water prevention in down -coal mining.
