为了有效提高露天非金属矿产资源开采量的预测精度，降低勘查误差，提出了露天非金属矿产资源综合勘查模型构建研究。利用矩阵分析法，将生态环境保护和经济发展作为划分的约束指标，根据露天非金属矿产资源勘查功能区划分原理，划分了矿产资源的勘查功能区。采用数学几何法，将非金属矿产资源分割成一系列的几何形状，根据非金属矿产资源的类别，计算非金属矿体的体积。基于非金属矿体的矿石量，计算了露天非金属矿产资源储量；利用变异函数，计算了矿产资源勘查区的品位值；结合露天非金属矿产资源的富集系数，构建了露天非金属矿产资源综合勘查模型，实现了矿产资源的综合勘查。实验结果表明，模型可以提高非金属矿产资源开采量的预测精度，降低勘查误差，具有更好的勘查性能。

Construction of comprehensive exploration model of open-pit nonmetallic mineral resources

In order to effectively improve the prediction accuracy of mining volume of open-pit non-metallic mineral resources and reduce exploration errors，a study on the construction of comprehensive exploration model of open-pit non-metallic mineral resources is proposed.Using the matrix analysis method，taking the ecological environment protection and economic development as the constraint indexes for the division，the exploration functional areas of mineral resources are divided according to the division principle of open-pit non-metallic mineral resources exploration functional areas.The non-metallic mineral resources are divided into a series of geometric shapes by using the mathematical geometry method，and the volume of the non-metallic ore body is calculated according to the category of the non-metallic mineral resources.Based on the ore quantity of non-metallic ore body，the open-pit non-metallic mineral resource reserves are calculated.The grade value of mineral resources exploration area is calculated by using variation function.Combined with the enrichment coefficient of open-pit non-metallic mineral resources，a comprehensive exploration model of open-pit non-metallic mineral resources is constructed，and the comprehensive exploration of mineral resources is realized.The experimental results show that the model can improve the prediction accuracy of non-metallic mineral resources exploitation，reduce exploration errors，and have better exploration performance.
