Drilling and blasting - WikipediaDrilling and blasting is the controlled use of explosives and other methods such as gas pressure blasting pyrotechnics, to break rock for excavation. It is practiced most often in mining, quarrying and civil engineering such as dam or road construction. The result of rock blasting is often known as a rock cut.

Frequency and scale of the blasting events are increasing to boost line production. Mines are approaching close to inhabited areas due to growing population and limited availability of land resources which has challenged the management to go for safe blasts with special reference to opencast mining. The study aims.
Line 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 line to rubble, which is removed for use as crushed stone. The noise, dust, and impact from explosions can result in noise pollution and.

The Basics of Blasting Vibrations and Noise. Highway construction projects; placement of sewer, water, gas and electrical services; residential and commercial building projects; and mining frequently require the use of explosives. In these applications, rock must be broken loose from the ground and blasting is the only.
Such occurrences demonstrate incorrect determination of the bounds of the blast area. Flyrock from a line quarry traveled about 930 ft and fatally injured a resident who was mowing grass on his property [MSHA 1990b]. In underground mining situations, the mine roof conditions, ground support system, and ventilation.
