摘    要：本文根据无底柱分段崩落法法开采倾中厚矿体的特点,运用椭球体理论,建立了放矿数学模型;应用电算数值模拟法,求得了这种采矿法的最优放矿参数和放矿指标;在此基础上,确定了这种采矿法开采倾斜中厚矿体的适用范围。 更多还原

Abstract: In this paper, by the use of ore draw ellipsoid theory and based on thespecificities of mining the inclined medium ore bodies with sublevel caving,the draw math model was finished. The best ore draw parameters and oredraw targets were got by the application of electronic computer numeralvalue similitude and the application range of this method was obtained ifthe inclined medium ore bodies were mined by the sublevel caving.
