A prerequisite for a safe working environment is that the pillars should adequately support the overburden and the pillar ribs and rooms should remain stable during mining. At present pillar dimensions are either based on experience at neighboring mines or on strength equations that were developed for metal or non-metal mines. This paper presents a pillar ...
MoreLimestone has a wide range of uses such as in cement, iron-steel, chemical and building construction industries etc. Limestone is also important as a reservoir rock for oil accumulations.

MoreLimestone forms when calcite or aragonite precipitate out of water containing dissolved calcium, which can take place through both biological and nonbiological processes. The solubility of calcium carbonate (CaCO 3) is controlled largely by the amount of dissolved carbon dioxide (CO 2) in the water.

MoreLimestone deposits are found throughout the world. They are “mined” in a process known as “quarrying.” This process varies depending on the use of the product. If it is to be made into cement, it is needed in small pieces so that it can be ground and calcined.
MoreMost limestone and dolomite are mined from open quarries, although in many areas economic and environmental considerations favor large-scale production by underground mining. The only carbonate materials not consistently recovered by surface or underground mining are shell products that are dredged from parts of U.S. coastal waterways.

MoreLimestone can also form through evaporation. Stalactites, stalagmites, and other cave formations (often called "speleothems") are examples of limestone that formed through evaporation. In a cave, droplets of water seeping down from above enter the cave through fractures or other pore spaces in the cave ceiling.
