露天煤矿数字地质模型的建立及在虚拟开采中的应用研究

为了对露天煤矿剥、采、排和土地复垦的进行预控制,需要对露天矿生产进行预演,计算相关数据。采用层面模型建立露天矿的地质模型,以"多对角线交换循环算法"结合"凸包推进算法"建立约束TIN结构层面。根据露天矿开采推进的特点建立以台阶为单元的分层式开采模型,在地质模型和开采模型的基础上,根据露天矿实际生产情况建立开采模板,采用"人工交互式推进"实现露天矿的虚拟开采。

Establishing of digital model of open-pit and its application in virtual mining

The production in open-pit is required to be rehearsed so as to compute the correlative data in order to carry through a pre-control for the peeling, mining, spoiling, and land reclamation in open coal mines. The lay model is utilized in the establishment of geological model for an open-pit, to install the restrict TIM restructure layers by means of combining the algorithm of multi-diagonals interchange circulation with the algorithm of convex package propulsion. According to the characteristics of step propulsion in open-pit, the mining model of delaminating type is structured with one step being as one unit. Based on the geological model and the mining model, according to the actual production situation the mining template is determined by using manual interactive propulsion style to realize the virtual mining in open-pit.
