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。
針對華北型煤田下組煤底闆突水脆弱性問題,在綜閤分析煤層底闆突水危險性影響因素的基礎上,攷慮到影響底闆突水因素的多麵性和不確定性,建立瞭煤層底闆突水脆弱性總體評價指標體繫。以山西紫金煤業11號煤層為例,運用基于改進AHP (三標度)的模糊綜閤評價法,對煤層底闆突水的脆弱性進行瞭綜閤評價。評價結果為:從井田中部嚮東西兩側,底闆突水脆弱性依次為中等、較脆弱、脆弱、中等。評價結果閤理可靠,為下組煤開採過程中奧灰水的防治提供科學依據。

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.
