Jordan has huge limestone reserves which are used to produce aggregates for construction purposes. These reserves are very important economic sectors in Jordan, but many of these reserves belong to quarries that are located near urban territories. The mining operation type is mainly open cast and this activity has fugitive dust sources that contribute to increasing air quality levels in the ...
Globally, no research has yet been undertaken on the health effects of opencast coalmining operations which span such large spatial extents and decadeslong time scale as those pending for the Douglasdale area of Scotland.

Openpit mining or opencast mining refers to a method of extracting rock or minerals from the earth by their removal from an open pit or borrow. It is a form of surface mining. The term is used to differentiate this form of mining from extractive methods that require tunneling into the earth, like longwall mining.

It is used for con
A major part of iron ore, nonferrous metals, brown coal, building materials and minerals for industry is being excavated in opencast mines. This type of mining has a deep impact on the natural strata. Opencast mining changes geological, hydrological and geotechnical conditions. It influences the existing ecological system and landscape.
Openpit, opencast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mines are used when deposits of commercially useful ore or rocks are found near the surface.

Open pit mining. Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.
Effect of opencast mining on soil fertility Mrinal K Ghose Centre of Mining Environment, Indian School of Mines, Dhanbad 826 004 Received 05 June 2004; accepted 08 October 2004 In the process of opencast mining, several changes occur in physical, chemical, and microbiological properties of soil as a result of mining and storage.
With open cast mining the overburden, which may be covered in forest, must be removed before the mining can commence. Although the deforestation due to mining may be small compared to the total amount it may lead to species extinction if there is a high level of local endemism. Oil shale
What Are the Disadvantages of Opencast Mining? Opencast mining, also known as surface mining or strip mining, has disadvantages that include disturbance of the environment and local ecosystems, exposure of radioactive elements and contamination of freshwater sources. The use of heavy machinery and blasting techniques also create environmental ...
Anne‐Marie Baker and Alan Younger, The influence of nitrogen and early drainage on production from grazed and cut grassland restored after opencast mining, Journal of the Science of Food and Agriculture, 41, 1, (1727), (2006).
Open cast mining is a type of surface mining in which mineral resources are removed from the earth through large holes or pits dug into the surface. The term "open cast mining" is used most commonly in Great Britain. In the United States, open cast mining is usually called openpit or opencut mining.
Aug 26, 2008· Abstract. Mining is widely regarded as having adverse effects on environment of both magnitude and diversity. Some of these effects include erosion, formation of sinkhole, biodiversity loss and contamination of groundwater by chemical from the mining process in general and openpit mining .
The openpit or open cast mining method is the obvious choice for a property with wide area of mineralization exposed or exists close to the surface and continues to greater depth. The open pit is opening the orebody from the surface by separate removal of ore and associated waste rocks.
Discuss the negative effects of open cast mining on the environment. Answers (i) Large scale blasting of rocks leads to instability of the basement rocks. Water collects in the hallows left by open cast mines creating ponds which becomes habitats for disease causing organisms.
The open cast method of mining involving blasting has contributed to land dereliction. From the survey, 11% of the total respondents interviewed ranked land disfigurement and use of explosives in blasting fluorite as the most critical environmental hazards.
Business processes for mining include physical design methods, scheduling collections, expelling and removal of waste materials from the pit. In the United States, there are several open pitmining projects in operation, extracting daily to support three levels of economics; local, country and global, with commodities worth billions of dollars.
There has been no commissioned research into the effects of opencast coal mining on the health of Douglasdale residents. There has, however, been a single individual, Dr. Dick van Steenis, who has investigated the health impacts of opencast coal mining as a public service, and without payment.
