摘　　要：600m以上深厚表土层煤矿立井钻井井筒的支护需采用高强钢纤维混凝土井壁。根据钻井井壁的施工条件和性能要求,介绍了高强钢纤维混凝土的配制原则,选择了原材料,进行了大量的CF80-CF100高强钢纤维混凝土的配制试验。并在此基础上,采用多目标灰色局势决策的方法确定了CF80-CF100高强钢纤维混凝土的最优配合比。Aiming at the reinforcement for coal mine shafts in the deep alluvium under 600 m and more, steel fiber concrete shaft lining should be adopted.According to construct condition and performance request of drilling shaft lining, preparation principle of steel fiber concrete is introduced and raw materials are chosen.Preparation tests of CF80-CF 100 steel fiber concrete are done.On basis of these tests,multi-target gray situation decision-making is applied to receive the optimal mix ratio of CF80-CF 100 steel fiber concrete.
