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 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 کاملRespirable Silica Dust Suppression During Artificial Stone Countertop Cutting
PURPOSE To assess the relative efficacy of three types of controls in reducing respirable silica exposure during artificial stone countertop cutting with a handheld circular saw. APPROACH A handheld worm drive circular saw equipped with a diamond segmented blade was fitted with water supply to wet the blade as is typical. The normal wetted-blade condition was compared to (i) wetted-blade plus...
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-...
متن کاملAirborne concentrations of chrysotile asbestos in serpentine quarries and stone processing facilities in Valmalenco, Italy.
Asbestos may be naturally present in rocks and soils. In some cases, there is the possibility of releasing asbestos fibres into the atmosphere from the rock or soil, subsequently exposing workers and the general population, which can lead to an increased risk of developing asbestos-related diseases. In the present study, air contaminated with asbestos fibres released from serpentinites was inve...
