灰色系统预测急倾斜深部矿体初探

Preliminary Research on Applying Grey System to Prediction of Steeply Inclined Ore Body in Deep Level

矿山需要提前预测矿体深部钻孔控制范围以下的资源情况,以便为后续的工程设计提供地质参考数据。灰色系统模型对样本量没有过多要求,也不需要服从典型的分布规律,很适合于利用灰色GM(l,l)模型建立验证模型和预测模型对急倾斜矿体的深部埋藏情况进行定量预测,从而为矿山深部探矿和开采设计提供参考依据。

The prediction of resource conditions beyond the control of the drill hole is needful for a mine so as to provide the corresponding reference data for the further geology work in advance. The grey system model neither requires much for the sample amount, nor need samples to follow the typical regularities of distribution, so grey GM(1,1) model is very suitable for establishing the validation model and the prediction model used to quantitatively predict the occurrence state of steeply inclined ore body in deep level. The prediction results can provide references for the exploration and mining design of deep-seated ore body.
