Abstract:
Purpose The purpose of this paper is to enhance the capability in managing the maintenance of the transportation process from a quarry to a crushing plant, measured by the availability value and the process capability value. Design/methodology/approach The maintenance management plan consists of plans for three levels of management: strategy, tactical and operational maintenance plans. The Deming cycle is a continuous improvement tool use for controlling and monitoring activities of the plans. There are three Deming cycles according to these plans, the first of which involves the improvement o

Abstract:
Regardless of the applied technology of coal mining, a technogenic resource of the open pit is formed – excess mined-out space. Excessive mined-out space should be understood as a part of the internal space of a pit that is not used for placing overburden in dumps. The excess mined-out space in the plan is limited by the following: on the flanks of the quarry field and along the uprising by the limiting contour of the quarry, along the inclination – by the possible position of the slope of the dump layer, as close as possible to the working area. The lower boundary corresponds to the position

Abstract:
Sand and gravel quarry planning must guarantee the public interest in the procurement of raw materials while ensuring environmental sustainability. An Analyzing Planning Support System for sand and gravel quarry plan can assist decision-makers during the planning process. The proposed Analyzing PSS uses integrating geologic, economic, environmental, and geographic information to quantify raw materials and the size of quarries. This kind of tool is useful to support public authority decisions. The study provides the results of an experience conducted in the province of Brescia (NUT 3 in Norther

The method proposed in the article is based on the mathematical apparatus for quantitative assessment of the reliability of majority schemes of structural redundancy of transport processes, which provide the availability and usage of several backup delivery channels in the transport process in case of any malfunction. The principle of multi-channel haulage is commonly used in quarries for transportation of overburden and minerals from benches by dump trucks, when excavators and dump trucks performing cyclic operations function as a single excavator-dump truck complex.

Abstract The highway project has a significant challenge in carrying out its work. The procurement of massive and constant materials is a significant problem. There are problems in basecamp selection: high transportation costs due to the distance to the raw material from the quarry, and on a managerial level, selection of basecamp location is the basis for construction firm management in controlling costs, time, and quality of the project. The literature review has mapped technical and non-technical factors in two decades. However, the lesson learned from historical data as a basis for decisio

Abstract. Large infrastructure building like the Florence Railway Station designed for high-speed rails requires a proper management of the huge quantity of waste originating from excavation activities. Such waste amounts require large areas for disposals, making abandoned areas or exhausted quarries and mines ideal sites for hosting the excavated wastes.A rectangular area of 500×70m delimiting the railway station has been excavated in two steps causing the removal of a 10m-thick soil layer per step: excavated earth and rocks would then be used for the environmental restoration of an area of 4

The City of Montreal, Quebec, Canada, took over the management, in 1988, of a former limestone quarry that was also used as landfill site. The surrounding population of this site was exposed to many nuisances related to the rock extraction and transformation and to the landfilling activities. So, the main goal of the city was to rehabilitate this degraded site, build a public park and give it back to the population. The site’s total area covers 192 ha. From this surface, 72 ha were devoted to the landfill. Over the years, 40 million tons of municipal solid waste have been landfilled. Building
