Quarrying. Quarries are of two different types, the pit quarry and the bank quarry. The pit quarry is one in which the stone is extracted from below the general level of the surrounding country, and, as a rule, the stone is elevated to the crushing and treatment plant on the surface. Some operations in limestone and granite are of this type.

A stone crushing plant is primarily involved in the manufacture of aggregates of various sizes (coarse aggregates, crusher run, rock sand and other fine aggregates) from basalt boulders. Coarse aggregates are usually used in ready mix concrete and asphaltic concrete. Crusher run is used for the bases and sub-bases for road making.

Dust is one of the most visible impacts associated with limestone quarrying due to the drilling, crushing and screening of the rock. The mine site conditions can affect the impact of dust generated during extraction, including rock properties, moisture, ambient air currents and prevailing winds, and the proximity to population centers.
Environmental hazards resulting from quarrying activities dates back to 1890's (BGS, 2010). The main issues of concern include visual impairment, damage to landscapes, traffic, smoke, noise, dust, damage to caves, loss of land, and deterioration in water quality (Iqbal and Shafig, 2010; Mate, 2012; Montgomery, 2012).
Among some groups of miners who live together in isolated locations, there is also risk of transmitting some infectious diseases such as tuberculosis, hepatitis (B and E), and the human-immunodeficiency virus (HIV). Miners' exposure varies with the job, its proximity to the source of hazards and the effectiveness of hazard control methods.
