Environmental Hazards of Limestone Mining and Adaptive
Method of mining largely depends on the characteristics of mineral deposits. For minerals that occur near the surface and larger deposits, like limestone, opencast mining process is used. Underground mining is conducted for deep-seated minerals like coal (UNDP and UN Environment 2018).

Limestone Quarrying and Processing: A Life-Cycle Inventory
Limestone can also be chemical in origin as is the case with travertine. Chemical limestone forms when calcium and carbonate ions suspended in water chemically bond and precipitate from their aquatic sources. Because of its high calcium content, limestone is usually light in color, although many variations exist.

Wirtgen Surface Miners – Limestone mining without drilling
Meanwhile, the previous use of explosives for limestone mining was having a detrimental effect on neighboring residential areas due to the noise generated and the ground vibrations. IFCEM found the solution in Wirtgen surface miner technology: In 2012, the company purchased a 2200 SM, in 2015 a second, identical model and in 2017 a 2500 SM.

Environmental Hazards of Limestone Mining | Education
Limestone mines use two types of blasting. Small explosive charges set along drilled lines free blocks of stone to be removed for construction. Large charges reduce whole areas of limestone to rubble, which is removed for use as crushed stone. The noise, dust, and impact from explosions can result in noise pollution and dust.

Achieving Safe Limestone Mining
By adding a 2500 SM Vario, the company was able to mine a total of 32,000m³ of limestone in 2018 – a significant increase from the 22,000m³ mined in 2017. The 2500 SM Vario is particularly suitable for hard rock, as is the case in Ube. Thanks to the central-drum concept, the drum is located very close to the centre of gravity of the 135-ton

Mining crushed stone is more involved because the deposits are consolidated, meaning solid rock formations. The most common types of crushed stone come from deposits of limestone, dolomite and granite. To produce crushed stone, the massive formation first is drilled with a pattern of holes loaded with explosives by a licensed blaster.
