  • Limestone Extraction Without Drilling and Blasting Agg-Net

    For years, the limestone was extracted by drilling and blasting and then wet processed into clinker in the cement plant. In a move to increase productivity and reduce costs, IFCEM became the first cement plant in the Ukraine to initiate the transition from the wet process to a dry process, a measure that optimized the mining method for material supply.

    Limestone extraction underground mining techniques

    Surface limestone mining. All over the world, the limestones are generally mined from a quarry or the open pit mining. It is the easiest way to remove the limestone without causing much destruction. In surface mining or open pit mining, the top soil and the overburden covering the mineral is removed. Then by the process of drilling the rocks or broken. Overburden or large rocks that are difficult to break through drilling are removed by the explosives to extract the limestone

    Drilling. Most blasting in mines involves charging explosives into holes drilled in rock. The entrance or mouth of a drill hole is called the collar and the end is the toe. Drilling is still carried out in some cases, in the ASM sector, by hand, using a hammer and chisel. This is obviously tedious and slow, especially in hard-rock mining conditions. Hand-drilled holes seldom exceed 400mm in

    25/04/2017· Rotary cutting creates the hole by shear forces, breaking the rock’s tensile strength. The drill bit is furnished with cutter inserts of hard metal alloys, and the energy for breaking rock is provided by rotation torque in the drill rod. This technique is limited to rock with low tensile strength, such as salt, silt, and soft limestone not containing abrasive quartz minerals. Rotary crushing breaks the rock by high point load, accomplished by a toothed drill
