Underground Limestone Mining

Underground Limestone Mining by Robert M. McKay and Michael J. Bounk The production of limestone aggregate from underground workings requires machinery to illuminate the rock face and to hoist miners into position to clean drill holes and load explosives for blasting the rock.

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

Blast Hole Drilling: The Basic Process RPM Drilling

Blast hole drilling is traditionally used wherever the mining company wants to explore the mineral composition or potential mineral yield of the area demarcated for their mining interests. Blast holes are thus a fundamental step in the exploratory mining process, and can be employed in both surface mining operations and underground mining

I UNDERGROUND BLASTING Mining and Blasting

The blasting procedure is the same as discussed previously. The production work can be subdivided into two categories: short-hole and long-hole blasting. Short-hole blasting The diameter and length of shotholes are usually limited to 43 mm and 4 m respectively. Short-hole blasting is usually used in breast stoping for narrow,

Drilling and Blasting Technical Aspects of Mining

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.

Dangers of Toxic Fumes from Blasting

blasting agents used in large-scale surface mine blasting do not detonate properly in boreholes of 1-inch diameter or less (ISEE, 1998). If the blasting agent is diluted by mixing with drill cuttings at the top or bottom of the borehole it may not detonate properly and excessive quantities of toxic fumes may be produced (Sapko, 2002).

Environmental Hazards of Limestone Mining Education

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.
