应用隶属函数对岩石可钻性进行分级

Apply Subordinate Function to Classfication of Rock Drillability

利用模糊数学中的隶属函数对岩石可钻性进行了分级，收到较好效果。该方法与其它分级方法相比，计算简便并克服了一些分级方法的不足，因此更加实用。

This paper applied subordinate function of fuzzy mathemetics to the classfication of rock drillability. It gained better result. The method counted simple and convenient and overcomes inadequacy of others, so more practical.
