Limestone deposits exist throughout the world. These alkaline sedimentary rocks were laid down mostly as deposits on the beds of ancient seas. A valuable natural resource limestone has many uses in construction agriculture and industry. Limestone quarries can be above ground or underground and can cover large areas. Environmental hazards from mining operations depend in part on the location characteristics and extent of the mining operations.

Limestone mining can affect ground water conditions. Limestone deposits often occur in association with karst a topography where limestone slowly dissolves away underground. The deposits result in sinkholes caves and areas of rock fractures that form underground drainage areas. When mining occurs in karst disruption to natural aquifers or flows of underground water can result. Often mining operations remove ground water to expose the quarrying site which can lower the water table and change how water flows through the rock formations.

Environmental Impacts Of Quarrying Limestone

Environmental Impacts Of Quarrying Limestone

Streams and rivers can be altered when mines pump excess water from a limestone quarry into downstream natural channels. This increases the danger of flooding and any pollutants or changes in water quality affects the surface water. In Germany salty water pumped from limestone quarries into rivers has degraded the water quality according to the International Mine Water Association. Upstream surface water features such as marshes ponds and wetlands can lose volume as their waters drain into the mine and are pumped out.

As water and rock are removed from mines the support they give to underground features is gone. Sinkholes can develop where the roofs of underground caverns are weakened or collapse. Collapse can be gradual or sudden. Although natural sinkholes develop over time man-made ones predominate in mine areas. Sinkhole formation can cease after mine dewatering is stopped and the water table is allowed to return to normal levels.

Limestone Mining Activities Uses Environmental Concerns

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. Underground forces from the blasts can cause sinkholes or change the drainage and water quality of underground aquifers. Construction equipment such as large trucks crushing machines and earth-moving equipment also contribute to noise and dust.

Apr 09 2020nbsp018332Although this doesnt hurt the environment in its natural form once the limestone is mined out sinkholes can form and disrupt underground waterways. This changes the natural water table. The actual mining process also changes existing waterways adding additional water to streams and other bodies of water that not only floods the surrounding area but adds pollutants to it as well.

Limestone is the raw material used to manufacture cement. Limestone is mainly mined at Athi River near Nairobi and at Bamburi near Mombasa. The limestone along the Coast extends to Mombasa Island and is mainly formed from remains of corals. Limestone rocks are dug up in large masses using open cast method and crushed using large mechanical rollers.

Limestone is a sedimentary rock that is composed primarily of calcite calcium carbonate CaCO3 and dolomite calcium magnesium carbonate CaMgCO32. It can vary in purity consistencyand hardness. The limestone can be a soft chalky material with microfossils a hard recrystallized mass a grainy sand-lime mass or a mass of fossil corals urchinsand shells.
