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.
In mining design, block model or three-dimensional model is usually established, and the volume calculation of irregular body is carried out through the model.It is found that the two models have their own deficiencies in practice, the calculation error of the block model is the discrete precision problem, The problem of time-consuming and unstable calculation of the body model is presented.In this paper, a semi-continuous semi-discrete model is proposed, and its application and practical application examples are given.It has been proved that the semi-continuous semi-discrete model has the advantages of fast calculation, small error and calculation Stability and other advantages, is a very effective calculation model in mine design.
