Limestone is a karst-forming rock, which produce landforms that are formed by dissolution, and represents about 10 percent of the world’s land surface. But limestone cannot be mined without impacting the environment.
Other problems were high capital costs on plants and facilities due to environmental regulations and the requirement of zoning and mining permits. These two dominant factors lead to the adaptation and selection of other materials that were created and formed to design alternatives for limestone that suited economic demands.
Some Issues in Limestone Mining. Limestone is most often mined from a quarry. However, underground limestone mines are found at places in the central and eastern United States, especially in and near cities. Underground mining of limestone has some advantages over surface quarrying and will probably increase in the future.

Apr 09, 2020· Limestone mining can pollute water and create sinkholes. When limestone dissolves while it's still in the ground, caves and gullies form, a natural phenomenon known as karst. Although this doesn't hurt the environment in its natural form, once the limestone is mined out, sinkholes can form and disrupt underground waterways.
Mar 08, 2017· Many cite coal mining and the subsequent environmental impacts but limestone quarrying should not be equated with mining and obtaining nonrenewable fossil fuels.

Jan 06, 2021· There have been many improvements and advancements in the application of neural networks in the mining industry. In this study, two advanced deep learning neural networks called recurrent neural network (RNN) and autoregressive integrated moving average (ARIMA) were implemented in the simulation and prediction of limestone price variation. The RNN uses long short …
Health and Safety Mining is a dangerous profession. The traditional occupational hazards such as coal dust inhalation, damage to hearing due to the noise in a mine and chemical hazards still stand but the changing nature of mining has led to a raft of new issues. As mines are getting deeper, the risk of collapse has greatly increased.
