Limestone is now mined using surface and underground methods. Surface quarrying is the most common method of producing limestone in Missouri. Also, it is typically the most economical method. Many surface operations are simply hillside cuts or open pit quarries.

Limestone. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth's sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is either limestone or dolomite. El Dorado Lime & Mineral Co Brief History Started as a narrow guage feeder line for the Central Pacific's Placerville branch, the El Dorado Lime & Mineral Co, was approximately a mile long serving a limestone mine.At some point, the original alignment of the line was abandoned with a new line being built from a new location.
1. Underground Mining Methods 1.1. Classification of Underground Mining Methods Mineral production in which all extracting operations are conducted beneath the ground surface is termed underground mining. Underground mining methods are usually employed when the depth of the deposit and/or the waste to ore ratio (stripping ratio) are The pictures below show that quarry, and beach rip rap, which is one use of the limestone. Most of the limestone is transported from this quarry by truck, but some is still moved by rail. In addition to limestone, Michigan also produces pure lime as well. Lime is purified limestone, and is often of more value to industry than is limestone.
Quarries are made when big deposits of commercially helpful minerals or rock are found close to the Earth's surface. Quarrying is a type of mining and is also called as open pit mining or strip mining. When minerals are found profound beneath the surface, a deep mine has to be dug to dig out them. 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 …

Granite is a common type of igneous rock. Igneous rocks are formed when magma is cooled underground creating a plutonic rock. This rock is extremely durable and hard, making it the perfect substance for construction uses in such items as countertops or flooring. Granite is formed underground by the cooling of magma. Mining is the extraction of valuable minerals or other geological materials from the earth from an orebody, lode, vein, seam, or reef, which forms the mineralized package of economic interest to the miner..
