·The need to achieve a balance between demand for aggregates and local communities desire to be protected from the potential negative impacts of quarrying is one which applies to both new and existing sites In particular quarry operators can be faced with significant resistance from local communities and action groups about the amount of dust generated
·Limestone is a fundamental raw material in various industrial sectors It is formed due to biochemical precipitation of calcium carbonate and further compaction over long periods of time
·The results of the dust measurement in the emission sources in the quarry were evaluated within the scope of Industrial Air Pollution Control and it was determined whether the dust prevention
·In industries including mining construction and machinery workplaces are prone to dust hazards [[1] [2] [3]] Dust is solid particles suspended in the air and people can suffer from a series of occupational diseases when they are exposed to dust environments for a long pollution has a tremendous impact on clean and safe production in Chinese
The exposure to respirable crystalline silica found in granite dust presents significant health hazards to quarry workers and nearby communities including silicosis and various respiratory ailments
From the laboratory results unhealthy conditions at the quarry site were confirmed and technical and administrative measures were suggested to reduce and control dust exposure at acceptable levels such as the implementation of an occupational health and safety management system integrated with other management systems
ensuring adequate ventilation; and use controls to minimise the amount of dust in the air such as on tool dust extraction local exhaust ventilation or wet cutting methods; using machinery or vehicles that have an enclosed cabin and ; using appropriate personal protective equipment including respiratory protective equipment
·Quarry dust can be used as a substitute for sand to improve the properties of lateritic soil Soosan et al 2001b by checking durability properties through the measurement of permeable voids

5 ·The dust suppression systems of the MobyDick Cannon Line utilise the principle of dust control through the finest water droplets A state of the art high pressure pump in combination with an efficient filter system and specially designed nozzles along with an aerodynamically shaped cone turbine ensure the optimal size and distribution of
·in filling subgrade in order to solidify the material and also to prevent dust Prevent coal ash and stone dust from dispersing Cover them properly in warehouses and piling yards except where they are to be used immediately Cover vehicles delivering materials to reduce spills Select asphalt mixing plant sites at least 500 metres away from human
·Hazard prevention and safety measures should be taken into account in the workplace either in the quarry or in the marble workshops with increased emphasis on risk management The risk management not only benefits in a healthier and happier workforce and increased productivity but also protects the health of the workers and promotes the
·The respirable dust limit formula suggests the first explanation a mine with a high silica % in the dust is required to keep the dust concentration low under the reduced standard
·Dust control maintenance of dust extraction equip ment and air filter systems Dust poses a potential health risk to quarry workers Dust is generated by drilling and sawing by blasting and excavation operations as well as by haulage There should be control measures in place to prevent dust reaching levels that could cause harm
·The exposure to respirable crystalline silica found in granite dust presents significant health hazards to quarry workers and nearby communities including silicosis and various respiratory ailments This study evaluates the efficacy of various pollution control measures implemented in granite quarr
·A large amount of mine dust may be produced in each production process of the mine For example when drilling without dust prevention measures the mine dust concentration in the operation site is close to 1 g/m blasting it is more than 1 g/m 3 sometimes even higher in the vicinity of the working higher the mechanization of mining the greater
·may be at risk from health hazards When it is considered that even with control measures in place people will still be at risk the occupational health surveillance will only be appropriate if the criteria listed are met Quarries Regulations 1999 In addition the Quarry Regulations require that pre employment medicals are undertaken These
