摘    要：本文从研究重力场和振动场矿石放出规律着手,提出了放矿中的分流原理。模拟试验证明,应用这一原理,改变了放出体中矿石流动速度的分布规律,可在不增加采切工程量和能源的条件下,扩大矿石流动范围,增加放出矿石量,减少矿石的贫化损失。

Abstract: The author started with the investigation of gravity field and the law of ore draw from vibratory area and suggested the principle of split flow of ore draw.The simulation test proved that the application of this theory had changed the velocity and distribution law of ore flow in ore body to be drawn Under the condition without increasing engineering quantity of cut and energy source,the ore flowing range could be enlarged,the quantity of ore draw could be increased and ore dilution and loss could be decreased.
