“…Bernardi et al (2020) used an ARENA simulation model to compare semi-mobile and fixed IPCC systems for open pit mines in terms of NPV and proximity to the target production rate. The simulation was run for a simplified cone-shaped hypothetical mine with hourly costs, and results showed that SMIPCC generated 10% higher NPV and was closer to production targets.…”

“…The results from a copper mine show that while the CAPEX of SMIPCC is 60% higher than TS, the OPEX is 43% lower because of low maintenance and labour cost, which results in a 34% saving in net present cost over a LOM of 20 years.

In-Pit Crushing and Conveying (IPCC) has gained momentum in recent years to replace trucks partially or fully in large open pit mines because of the shovel-truck system's increasing fuel and labour costs and conveyor systems' low operating costs and less greenhouse gas emissions. This article reviews the most recent literature since 2010 on short-term planning, based on different formulation and solution approaches, and IPCC, based on primary objectives such as optimum crusher location, economic/environmental comparison etc., to find the research gaps and future research opportunities in short-term planning with IPCC. The review reveals that hardly any short-term planning model can generate mine extraction sequences with IPCC integration. Therefore, a short-term planning methodology considering the IPCC system would be a pioneering step in the mine planning literature. Hence, the authors propose a theoretical short-term planning framework with IPCC as a future research direction.

“…The model is used as the basis to develop a methodology for calculating optimal arrangement of the IPCC technology and the time for transfer. Paper [7] studied configuration of a mine field geometry and models discrete events in the IPCC system to evaluate the possibility of its application and identification of drawbacks. Study [8] compares cyclic and IPCC technologies of iron ore mining and transportation by analyzing the costs of previous feasibility study.…”

Purpose is to substantiate the use of an in-pit crushing and conveying technology at the open pits with complex structure of the working zone, which technological complex includes inclined and steeply inclined conveyors for improved economic efficiency of mineral mining at deep levels. Methods. The study applies a complex method including: technical-economical analysis of the practice of mining enterprises, experience of using conveying units at concentration plants and open pits; mining-geometrical analysis in terms of open pit sections – to identify the structure of the working zone of a deep open pit wall and its features along the depth; structural developments – to improve the design of a steeply-inclined conveyor; simulation modelling of the technological processes – to select optimal technical solutions. Findings. Basing on the performed studies, it has been identified that transfer to a new trend of the in-pit crushing and conveying technology, considering the structural features of the working zone of a deep open pit, is rather prospective. In this context, it is expedient to use inclined conveyors or deep-trough conveyors on the sites of an open pit wall with the inclination angle of 10-18°; in case of sites with the inclination angle of 30-36°, it is recommended to use steeply inclined conveyors. Originality. For the first time, a relation between the working zone of a deep open pit and formation of the structure of technological complexes has been identified. Dependences of the boundary inclination angle αn of a pipe conveyor on the angle of non-filling θ of its belt with the cargo at different coefficients of cargo-belt friction have been defined. Practical implications. The obtained results make it possible to widen the application sphere and increase the efficiency of mineral mining with the use of in-pit crushing and conveying technology.

“…On the other hand, semi-mobile IPCC systems have different strategic mine planning and sequence requirements than the truck-and-shovel counterpart; the crusher and conveyor cannot be relocated frequently due to the high relocation costs [8]. Moreover, the massive initial investment associated with IPCC systems forces the mine planners to design the mining strategy precisely in the long run, especially in large-scale mines [9].…”

In-pit crushing and conveying (IPCC) systems have drawn attention to the modern mining industry due to the numerous benefits than conventional truck-and-shovel systems. However, the implementation of the IPCC system can reduce mining flexibility and introduce additional mining sequence requirements. This paper investigates the long-term production scheduling and the crusher relocation plan of open-pit mines using a semi-mobile IPCC system and high-angle conveyor. A series of candidate high-angle conveyor locations is generated around the pit limit, with a crusher located along each conveyor line. Each conveyor location is solved independently by an integer linear programming model for making production scheduling and crushing station decisions, aiming to maximize the net present value (NPV) considering the material handling and crushing station relocation costs. The production schedule with the highest NPV and the associated conveyor and crusher location is considered the optimum or near-optimum solution.
