Dust produced during quarrying is a major contributor to air pollution. However, it depends on the size of dust particles and their chemical impact, the particles’ concentration in the air, and the local microclimatic conditions. For instance, some quarries produce clouds of dust with high amounts of reactive alkaline, while others produce ...
fatal lung disease. Information on the chemical composition of the quarry dust is important as it forms a vital baseline for among others the detection of the undesirable health effects among the quarry workers. The aim of the study was to find out the occupational health risks posed by the dust to the quarry
Environmental Impacts Commonly Associated with Mining and Quarrying 3. Deep mining refers to the extraction of deep-lying mineral resources such as coal from subsurface workings. It usually involves driving a vertical shaft from the surface to the level of the mineral deposits, which are then accessed by means of horizontal tunnels.
Three of the key major hazards — dust, vibration and noise — are discussed below. Dust. Dust is present in all quarrying and opencast mining operations. While it is often considered to be more of an environmental issue, dust is a potential health risk and it is the nature of the dust …
Quarrying in the mining industry is not a new phenomenon ( shrock, 2002 ) dealing with the effects of quarrying intermediation and its underlying principle (Scholtens and Van Wenveen, 2000) Globally virtually almost all quarrying industries companies did not have the immune to the unprecedented period of economic unrest.
A. Dust from mining and quarrying operations, if allowed to enter the atmosphere creates an uncomfortable working environment, causes excessive wear on machinery, reduces visibility and increasing the risk of accidents.

Guide to the prevention and suppression of dust in mining, tunnelling and quarrying. The object of this manual is to indicate those operations in mining, tunnelling and quarrying which are likely to give rise to airborne dust, and to describe ways in which the concentrations may be determined and how they may be eliminated or reduced.
despite positive effects, there are several negative effects associated with quarrying activities. This includes loss of biodiversity, land dereliction, air pollution, and water pollution among others. There are several legislations enacted in Kenya which provide guidelines on how mining and quarrying …
Health Hazards of Mining and Quarrying. The principal airborne hazards in the mining industry include several types of particulates, naturally occurring gases, engine exhaust and some chemical vapours; the principal physical hazards are noise, segmental vibration, heat, changes in barometric pressure and ionizing radiation.
quarry dust to be used as an effective filler material in concrete instead of fine aggregate. Some studies were reviewed by Chandana et al., [22], on physical and chemical properties as per listed in Indian Standard. Table 1 and Table 2 show the physical properties and chemical properties of quarry dust and natural sand respectively.

The negative impact of quarrying activities, such as health problems and air pollution is among the ... A review of mining activities is necessary to understand where dust originates in mining operations, and the environmental factors affecting dust emissions. Since the focus of this research is on surface mining
An increase in quarrying, open-cast mining and road traffic suggest that dust deposition onto vegetation may be increasing. This review describes the physical and chemical characters of a range of dust types. The effects of dust on crops, grasslands, heathlands, trees and woodlands, arctic bryophyte and lichen communities are identified.
The impacts of quarrying on sur- face water and ground water (see below) can impact wetland riparian, and aquatic habitat which, in turn, can impact biota. Water Quality. Karst systems have very low self- puri fi cation capabilities (Kresic and others, 1992), which makes karst water very susceptible to pollution.
The impact of dust from a nearby mine on local amenity depends on the distance from the mine site and climatic conditions such as wind. Concerns about amenity from mine site dust often relate to visibility of dust plumes and dust sources. Visible dust is usually due to short-term episodes of high emissions, such as from blasting.

4 The specific objectives of the study are: 1. To identify the negative impacts of quarry activities on the local environment of the study areas. 2. To assess the views and awareness of communities on the impact of stone quarry. 3. To examine the health impact of stone quarry on site residents. 1.5.
All gravel quarries create and emit dust particles strongly associated with health problems such as lung cancer, 1 heart disease, 2 stroke, 3 and reproductive issues. 4 Dust created by blasting and crushing releases Air Quality Silica dust (crystalline silica). This particulate is a known carcinogen, naturally occurring in rock, and is a byproduct of aggregate processing (excavation, blasting ...

Jul 23, 2021 Haul road dust impacts include reduced visibility, respirable dust risks, fugitive dust emissions, excessive water consumption, and plant and roadway maintenance costs. The tough upper layer skin developed on the roadway surface. Quarry Mining has also developed a dosing system suitable for quarries and civil applications.
the quarry is located at the southern edge of the air force academy and dates to the 1900s. the first rock slide, on dec., brought 2 million tons of limestone crashing down the steep, stair stepped ledges in the center of the quarry, generating a dramatic plume of dust and lots of …
and its effects on public health, agriculture and the environment. In addition, the legacy of mining has left thousands of sites in Africa contaminated by mining and associated mine dumps such as tailings and slag material. On the other hand, the number of studies focused on the impacts of mining …
laws governing the quarrying and mining industries are observed through enhanced surveillance. Licenses of the quarry owners who do not adhere to the set laws should be revoked. Compliance monitoring visits to quarry sites should be undertaken routinely so as to minimize the negative effects of quarrying operations on humans

Aggregate mining is an extractive use of resources: mining alters the landscape and its natural hydrologic system. When a new pit or quarry is proposed or when an existing operation needs to expand, local governments and citizens typically have many questions about the impacts mining might have.
The most common processes that produce respirable silica dust in mining and quarrying are drilling, blasting and cutting silica-containing rock. Most holes drilled for blasting are done with an air powered percussion drill mounted on a tractor crawler. The hole is made with a combination of rotation, impact and thrust of the drill bit.
