半连续半离散模型在矿山设计中的应用

Application of a semi-continuous and semi-discrete model to mine design

矿山设计中通常会建立块体模型或三维体模型,并通过模型来进行不规则体的体积计算.实际应用中发现两种模型有各自的不足,块体模型存在计算误差即离散精度问题,三维体模型存在计算耗时多及不稳定问题.本文提出了一个半连续半离散模型,给出了该模型算法及具体应用实例.实践证明,半连续半离散模型具有计算速度快、误差小和计算稳定等优点,是矿山设计中一种非常有效的计算模型.

Mining design generally needs to establish a block model or a three-dimensional solid model for calculating the irregular geometrical volume. It is found that in practical applications the two models have their own disadvantages. The block model has the problem of computation error, i.e. discretization accuracy, and the three-dimensional model has the disadvantages of long time consu- ming and instability. In order to solve these problems existing in the two models, this paper proposed a new semi-continuous and semi- discrete model and subsequently provided the model algorithm and practical cases. Research results illustrate that the proposed semi- continuous and semi-discrete model has the advantages of high computing speed, low error, and calculation stability, so it is a high efficiency method for mining design.
