ABSTRACT This paper proposes a real-time multi-agent fleet management strategy for autonomous underground mines vehicles. The fleet management strategy is based on multi-agent technology and includes a novel variation of the Contract-Net protocol. This paper also proposes a set of conflict management procedures to deal with the narrow nature of underground drifts, as well as the sequencing of trucks’ loading activities. This strategy is tested in a simulated environment based on an industrial case study. Both the strategy and the test environment were implanted using AnyLogic. More specifically, the fleet management activities addressed are dispatching, routing and traffic management of mining vehicles, which deal respectively with the assignment of the next destination to a vehicle that has just completed a task; the choice of the route to be followed to reach the selected destination; and traffic coordination in the underground transportation network, made up of one-lane bi-directional road segments. To evaluate the proposed solution, an agent-based simulation model of a Canadian underground gold mine is implemented with AnyLogic. Results show that the proposed coordination strategy outperform the one currently employed strategy by the mine under investigation.
摘要提出了一种井下自主车辆实时多智能体车队管理策略。该机队管理策略基于多代理技术,包括合同网络协议的一种新变体。本文还提出了一套冲突管理程序,以处理地下巷道狭窄的性质,以及卡车装载活动的顺序。该策略在基于工业案例研究的模拟环境中进行了测试。该策略和测试环境都是使用AnyLogic植入的。更具体地说,处理的车队管理活动是采矿车辆的调度、路线和交通管理,它们分别处理指派刚完成任务的车辆前往下一个目的地的问题;选择要遵循的路线,以达到选定的目的地;并且交通协调在地下交通网络中,由单车道双向路段组成。为了验证该方案的有效性,利用AnyLogic软件实现了加拿大某地下金矿基于agent的仿真模型。结果表明,所提出的协调策略优于该矿山目前采用的协调策略。

A new optimisation model for the selection of optimal cut-off grade using multi-sequential decision algorithm in open-pit metalliferous deposits 利用多序列决策算法建立了露天金属矿床最佳品位选择的优化模型

ABSTRACT The cut-off grade (COG) is a simple economic criterion that distinguishes between ore and waste, while the optimum COG demonstrates the best techno-economical strategy to utilise a geological reserve. The COG optimisation process is dynamic and, therefore, must be optimised at all processing stages. The classical approach of Lane’s algorithm is subjective in nature; he makes the mill’s head grade constant once and then makes it dynamic. So, to overcome these limitations, a new algorithm for determining a global optimal COG using a multi-sequential decision algorithm based on dynamic programming for open-pit metalliferous deposits has been presented in this paper.
摘要边界品位(COG)是区分矿石和废物的一个简单的经济标准,而最佳COG表明了利用地质储量的最佳技术经济策略。COG优化过程是动态的,因此必须在所有处理阶段进行优化。莱恩算法的经典方法本质上是主观的;他使磨机的原矿品位保持不变一次,然后使其动态。因此,为了克服这些限制,本文提出了一种基于动态规划的多序列决策算法来确定露天金属矿床全局最优COG的新算法。

ABSTRACT This study aims to research the implications of rubber powder utilisation, from tires recycling, in the deformability and strength properties of CPB. In the end, it will be concluded that mine paste backfill with recycled rubber materials contributes to the decrease of waste tire pollution and improve some mechanical properties of the filling body. For that purpose, tests were carried out to determine the uniaxial compressive strength, the elastic energy of deformation, Young’s modulus, and Poisson’s ratio in specimens made up of mine tailings, Portland cement, wastewater, rubber powder, and plasticisers. The analysis of experimental data determines that recycled rubber makes fresh slurry have better performance in flow characteristics. In the hardened state, recycled rubber reduces the uniaxial compressive strength of the specimens and Poisson’s ratio, but other features like deformability increase (Young’s modulus decrease) that enhance the ability to absorb elastic strain energy of the filling body. As a result, the study indicates that recycled rubber is applicable to rockburst prevention. The findings of this study provide both invaluable information and industrial applications for the efficient management of solid waste, based on sustainable development and circular economy.
摘要本研究旨在研究轮胎回收利用胶粉对CPB变形性和强度性能的影响。最后得出结论,采用再生橡胶材料进行矿泥回填有助于减少废轮胎污染,改善充填体的一些力学性能。为此,进行了测试,以确定由尾矿、硅酸盐水泥、废水、胶粉和增塑剂组成的试样的单轴抗压强度、变形弹性能、杨氏模量和泊松比。通过对实验数据的分析,确定再生橡胶使新鲜浆料具有更好的流动特性。在硬化状态下,再生橡胶降低了试样的单轴抗压强度和泊松比,但其他特征,如变形能力增加(杨氏模量降低),增强了吸收填充体弹性应变能的能力。研究表明,再生橡胶适用于岩爆防治。这项研究的结果为基于可持续发展和循环经济的固体废物有效管理提供了宝贵的信息和工业应用。

A Multiple Objective Hybrid Algorithm for Daily Ore Blend in Oil Sands Mines 油砂矿日混矿的多目标混合算法

ABSTRACT Oil sands mining contributes to the Canadian daily oil production by producing 1.617 million barrels per day. Processing oil sands is a complex operation with a critical sensitivity to the properties of the blended ore at the crusher that must follow the slurry pipeline and separation tank requirements. The blend optimisation in oil sands mines is a tedious work performed mostly manually by the mining engineers at the mine sites and requires fine-tuning as shovels move from one block to another in the same mining face. Miscalculations leading to deviation from the target properties cause inevitable economically and operationally expensive issues to the value chain including but not limited to sanding the pipeline, separation tank hick-ups, etc. Herein, we present a hybrid multi-objective algorithm addressing abovementioned issues in daily blending process and providing the operation crew with a clear practical production target at each mining face. The algorithm takes the processing targets as inputs and minimises deviations from each desired target by considering material properties at mining faces, the capacity of trucks, and production rates of active shovels.
摘要油砂开采为加拿大的石油日产量贡献了161.7万桶。油砂加工是一项复杂的操作,对破碎机中混合矿石的性质具有关键敏感性,必须遵循矿浆管道和分离罐的要求。油砂矿的混合优化是一项乏味的工作,主要由矿场的采矿工程师手动执行,并且当铲子在同一工作面从一个区块移动到另一个区块时,需要进行微调。导致偏离目标属性的错误计算会给价值链带来不可避免的经济和运营成本问题,包括但不限于管道打磨、分离罐增厚等,我们提出了一种混合多目标算法来解决日常混合过程中的上述问题,并为操作人员在每个工作面提供了一个明确的实际生产目标。该算法将处理目标作为输入,并通过考虑采矿工作面的材料特性、卡车容量和主动铲的生产率,最大限度地减少与每个期望目标的偏差。

Experimental study on the natural mixing behaviour of waste rocks poured in a paste backfill 废石在膏体充填体中的自然混合特性试验研究

ABSTRACT

Underground produced waste rocks (WR) are typically hoisted and stored on the ground surface as WR piles. The practice requires energy consumption for transporting the WR from underground to ground surface and generates additional operation costs. An alternative practice is to directly pour the WR into mine stopes being filled with paste backfill. However, the natural mixing behaviour of WR poured in a paste backfill has never been studied. To fill this gap, a series of physical model tests have been performed for the first time in the laboratory to understand the natural mixing behaviour of WR and paste backfill. The definitions of solids content by mass of WR and mixing degree are for the first time proposed to quantitatively evaluate the mixing behaviour between the poured WR and paste backfill. The test results show that the penetration of waste rocks into paste backfill and mixing degree can be improved through the use of paste backfill of low solids content, large particle sizes of waste rocks and/or through the increase of falling height of poured waste rocks. The proposed definitions can be used as good indicators to quantitatively evaluate the mixing quality of the natural mixture.

摘要地下废石通常被吊装成废石桩储存在地面上。这种做法需要将水水从地下运输到地面的能源消耗,并产生额外的运营成本。另一种做法是直接将水冷液倒入采场进行膏体充填。然而,在膏体充填体中灌入水凝土的自然混合特性尚未得到研究。为了填补这一空白,首次在实验室进行了一系列物理模型试验,以了解WR和膏体充填体的自然混合行为。首次提出了水回填体固体质量含量和混合度的定义,定量评价了水回填体与膏体的混合特性。试验结果表明,采用低固含量、大粒径废石的膏体充填体和(或)提高废石倾倒高度,可以提高废石对膏体充填体的渗透程度和混合程度。提出的定义可以作为定量评价天然混合物混合质量的良好指标。
