厚煤层开采方法是煤矿高产高效生产的关键因素之一。根据王庄煤矿8101工作面采矿地质条件，针对厚煤层采煤方法选择的模糊性和不确定性因素，确定了影响厚煤层采煤方法选择的因素，运用多级模糊综合评判方法进行综合评判；建立了基于 BP 神经网络的厚煤层开采方法评价模型，对王庄矿影响因素归一化结果进行了预判。研究结果表明，大采高一次采全高的模糊综合评判向量 B 值最大，为0.41233；BP 神经网络方法指数最高，为0.7479，可作为王庄矿厚煤层开采的首选方法。
厚煤層開採方法是煤礦高產高效生產的關鍵因素之一。根據王莊煤礦8101工作麵採礦地質條件，針對厚煤層採煤方法選擇的模糊性和不確定性因素，確定瞭影響厚煤層採煤方法選擇的因素，運用多級模糊綜閤評判方法進行綜閤評判；建立瞭基于 BP 神經網絡的厚煤層開採方法評價模型，對王莊礦影響因素歸一化結果進行瞭預判。研究結果錶明，大採高一次採全高的模糊綜閤評判嚮量 B 值最大，為0.41233；BP 神經網絡方法指數最高，為0.7479，可作為王莊礦厚煤層開採的首選方法。

Mining method in the thick seam is one of the key factors for the high production and high efficient mine. According to 8101 working face mining geological conditions of Wangzhuang Coal Mine,the selection of mining method in the thick seam fuzziness and un-certainty,the factors affecting the selection of mining method in the thick seam,the multilevel fuzzy comprehensive evaluation method for comprehensive evaluation;thick coal seam mining method for construction of made based on BP neural network evaluation model,the in-fluence factors of Wangzhuang Coal Mine,the normalized results predicted. The results show that fuzzy comprehensive evaluation vector B maximum of once large mining fully height overall height is the largest,0. 412 33;"JP index" BP neural network method is the high-est,0. 7479,it can be used as the preferred method for thick coal seam mining in Wangzhuang Coal Mine.
