Limestone is particularily suitable as a road building material due to its high compressive strength and binding ability. Gleeson Quarries is one of the leading producers and suppliers of Clause 804 and Clause 810 road materials to the local authorities and contractors for road building and improvement schemes.
material from which aggregate, cement, lime, and building stone are made. For the purposes of this report, limestone will be used as a sample for crushed rock. One product of limestone mining is lime. A wide range of industries use lime for a myriad of uses. It is used in many of the products and materials Americans use every day,
over drilling and blasting is that the limestone can be loaded directly onto trucks by means of a powerful transfer system. Eurocement makes use of further loading methods, however. If, for example, material is required for a temporary embankment stabilization, the surface miners discharge the cut limestone sideways onto a pile.

Bench – A horizontal ledge from which holes are drilled downward into the material to be blasted. Binary Explosive – A blasting explosive formed by the mixing of two plosophoric materials, for example, ammonium nitrate and nitromethane. Blast Pattern – The plan view of the drill holes as laid out for blasting.
The drill and blast method is used in many quarries to win stone for crushing, but there are alternatives. Patrick Smith reports. European restrictions on blasting operations are now so rigorous that some quarry operators have abandoned the practice in favour of other methods.
