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.

Apr 04, 2017 Mine workers may become ill or die if they remain in an area where toxic fumes levels are high. Between 1994 and 2005, eight miners were injured by exposure to blasting fumes. Surface blasting breaks up rock and frequently throws rock away from the blast site. Mine workers may be killed or injured by rock thrown by a blast.

Procedures For Blasting

blast. Modification of blasting procedures should include limiting the size and frequency of blasts to limit the production of noxious fumes, and stripping of the overburden prior to blasting and excavating the shot rock immediately after blasting to allow the venting of gases. The use of vent holes or vent pits may also be necessary.

Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15 of the Earths 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.

Wirtgen Surface Miners Limestone Mining Without Drilling

Oct 16, 2018 In order to ensure that the material extracted from the quarry is as dry as possible, a radical change in the mining method was necessary. Meanwhile, the previous use of explosives for limestone mining was having a detrimental effect on neighboring residential areas due to the noise generated and the ground vibrations.

Investigation Of Crushed Aggregate As Stemming Material

Jul 12, 2015 The drill cuttings and crushed aggregates were used as stemming material as shown in Fig. 1a, b for conducting the trial blasts. The blast trials have been conducted in a leadzinc mine, on the top overburden rock formations Fig. 2a, b. The geology of the mine entailed a stratiform, sediment-hosted leadzinc deposit that occurred in pre-Cambrian banded gneissic complex BGC.
