在实验的基础上,分析了放矿口宽度对放出量和散体流动参数的影响,改进了随机介质放矿理论,揭示了放矿口宽度对散体移动规律的影响,并指出了其影响范围.将改进后的随机介质放矿理论与原来的随机介质放矿理论进行了对比,3个矿山实验结果表明,改进后的随机介质放矿理论与实际符合较好.提出了确定采场结构参数的新方法,当放出体为非标准椭球体时,上下分段菱形布置的放出体三点相切时可得到最优的采场结构参数.该方法的提出,进一步扩大了随机介质放矿理论的应用范围.
On the basis of the experiment, the influence of the discharge mouth width on the discharge and dispersion flow parameters was analyzed, the random medium drawing theory was improved, the influence of discharge mouth width on the movement of the dispersion was revealed, and its influence was pointed out The comparison between the improved random media draft theory and the original random media draft theory shows that the experimental results of the three mines show that the improved random media draft theory is in good agreement with the actual situation.The paper proposes a method to determine the stope structure The new method of parameters, when the emitter is a non-standard ellipsoid, the optimal stope structure parameters can be obtained when the emitter of upper and lower segment rhombus arrangement is tangent at three points.This method is proposed to further expand the random ore bed The application of theory.
