| 摘 要： | 底部放矿的崩落法在国内外金属矿山地下采矿中应用广泛．研究底部放矿理论可为设计改进采场结构、出矿工艺和出矿作业提供理论支持。本文系统地考虑二次松散的影响，推导出了放出漏斗和放出体方程，并分析了方程中各参数对放出体形态的影响，该方程与试验数据拟合程度高．具有很高的实用价值。

| Abstract: | The caving method with boltom discharging is widely used in underground mining in metal mines in the world, Studying the ore-drawing theory of bottom discharging can provide the support for designing and improving the stope structure and the process and operation of ore drawing Based on considerations of the influence of the second loosening, the drawn-funnel and drawn-body equation is deduced, and the influence of each parameter in the equation on the form of drawn-body is analyzed The equation fit highly with the experiment data and has high application value. |
