Cement manufacturing begins with quarrying operations in which limestone in mines is quarried and brought to crusher for crushing Limestone quarries are opencast mines Often limestone appears as an outcrop right on the surface At other times it is under an overburden that can vary in depth but is generally less than 3 metres thick
In this study we investigated the impact of quarrying as an environmental ethical crisis The need for the study arose when we realised the deteriorating effect of the quality of life in our community which is located next to a limestone quarry To obtain a deeper understanding of the adverse impact on the environment and the quality of life of the people living in the
Electrical energy consumption was considered as the main driver of GHGs accounting for approximately % of total fossil fuel CO2 emissions A final point should be noted that data uncertainties in environmental assessment over the complete life cycle of limestone quarrying operation have to be carefully considered
The limestone is off white and has a microcrystalline structure The limestone layer is nearly horizontal with a strike of approximately 240° 280° and a dip angle of 15° 25° The surface coverage is a Quaternary loess layer Q 2 3 and an artificial soil layer The loess is sandy brown and contains caliche nodules
