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。

The mining program of concentrated parallel bunch blast holes and floor-funnel mining features the ore blowing-down with concentrated parallel bunch blastholes.the drilling and haulage at same level, "three-in-one"actual mining of shaft drilling, funnel openingout and ore blowing-down. The program is suitable for mining the gentle- inclined, medium thick and above orebody with unstable roof and floor with advantages of simple structure, lower ratio of extraction-to-cut and loss labour intensity.

密集平行束孔落矿的底盘漏斗采矿方案的特点是:用密集严行束孔落矿;凿岩与出矿水平合二为一;实行“掘井、劈漏、落矿三位一体”的回采工艺。该方案结构简单、采切比低、工人劳动强度低,适于开采缓倾斜顶底围岩不稳固的中厚以上矿体。

On the basis of the analysis of the mining methods for extraction of gently inclined medium thicknes ore bodies and considering the current state of mineral resource in China,a new mining method for extraction of such ore bodies with greater value and higher grade ore was developed,the features of which are discontinuous roof caving with longhole blast, continuous mining,fewer working faces,high produtivity, simple stope structure, safer operation and good ventilation condition.

On the basis of the analysis of the mining methods for extraction of gently inclined medium thicknes ore bodies and considering the current state of mineral resource in China,a new mining method for extraction of such ore bodies with greater value and higher grade ore was developed,the features of which are discontinuous roof caving with longhole blast, continuous mining,fewer working faces,high produtivity, simple stope structure, safer operation and good ventilation condition. Structure characters of the me thod,development and cut-off workings, stoping operation, pillar recovery, treatment of stoped-out area and ventilation were discussed in detail. Stope productivity of the mining method was 100 t/d and the mining cost was 21.81 RMB/t.

在分析国内外缓倾斜中厚矿体所使用的采矿方法的基础上,根据我国矿产资源现状,寻求一种新的采矿方法,用于开采矿石价值、品位较高的缓倾斜中厚矿体,本法就是在这种情况下提出来的。该法采用深孔间隔放顶,连续回采,工作面少,生产效率高;采场结构简单,作业安全,通风条件好。本文详细介绍该法的结构特点、采切工程、回采作业、矿柱回收、空区处理及通风。本法采场生产能力为100t/d,采矿成本为21.84元/t。
