A Short-term Production Planning Model for Dimension Stone Quarries
In this paper, problem of short-term production planning for dimension stone quarries was mathematically modeled using a binary integer programming. The model includes an objective function, which was founded as the minimization of the costs due to the total cutting planes of the blocks. This objective may cause to maximization of the net present value (NPV) in dimension stone quarries. During ...
متن کاملUtilization of Soft Computing for Evaluating the Performance of Stone Sawing Machines, Iranian Quarries
The escalating construction industry has led to a drastic increase in the dimension stone demand in the construction, mining and industry sectors. Assessment and investigation of mining projects and stone processing plants such as sawing machines is necessary to manage and respond to the sawing performance; hence, the soft computing techniques were considered as a challenging task due to stocha...
متن کاملProduction of artificial stone slabs using waste granite and marble stone sludge samples
In this work, the waste stone sludge obtained from the granite and marble stone processing factories was used for the manufacture of artificial stones using vibratory compaction in a vacuum environment. The results obtained showed that water absorption and density increased, and the flexure, compressive, and tensile strengths decreased with increase in the content of the waste stone sludge. The...
متن کاملInfluences of limestone stone quarries on groundwater quality
Rapid population growth and increasing demand for the modern settlement has led to the increase of environmental pollution. Limestone quarry is one among the activities that affect environment and ecosystem in Pemba Island-Zanzibar. Quarrying activities brought an inevitable destruction to the environments ranging from excavation, soil and land degradation, loose of biodiversity and water pollu...
متن کاملOccupational injury proneness in young workers: a survey in stone quarries.
OBJECTIVES Workplace injuries are of concern in adolescent and child workers. The factors of such injuries are important for injury prevention. This study explored the predictors of injury in such workers. METHODS This study was carried out in stone quarries and included 147 children and adolescent workers (81 males and 66 females). The mean age of the subjects was 11.3 years. An interviewer-...
