In mechanical drilling, machines such as hammer drills, percussive drills or rotary drills are used depending on the nature of the rock. In the quarrying by blasting, the diameter, depth, number, and spacing of boreholes require very careful considerations for getting the most beneficial result.
Quarry generally needs feeder, crushing equipment, screening equipment, transport equipment and so on. Different production lines are configured according to different production requirements, small to dozens of tons per hour, large to hundreds of tons, thousands of tons. The crushing equipment includes coarse/primary crushing …

Before quarry operations begin, extensive investigation, modeling and definition of the available reserves are undertaken. Geological investigationGeological investigations are based on maps and field studies. Representative samples are taken from the site for chemical and physical testing, and to determine their suitability for calcination.

The depth of boreholes is controlled by the depth of the soil that is under the influence of bearing pressure of the foundation. The recommended borehole depth is equal to one to three times the width of the loaded area. This is because it is suggested that bearing pressure below this depth would cause detrimental effect on the structure.
