    Consider that drilling and blasting are the first operations performed in any hard rock quarry operation. Therefore, the results of these operations will affect more down-line activities, such as loading, hauling and crushing, than any other processing operation. Photo by Tom Hingst.

The relation between blasthole diameter and face height is approximately: D = 0.001 to 0.02 H Burden (B) : This is the distance in metres from a blasthole to the nearest free face and has the following approximate relation: B = 25D to 40D Or B = 25D to 30D for hard rock B = 30D to 35D for

  • Selective limestone mining without drilling or blasting

    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. One benefit here is that the cutting pro-cess is always entirelyDRILLING & BLASTING OPERATIONS SanDiegoCounty.gov,DRILLING & BLASTING OPERATIONS Date Initiated: June 7, 1993 Dates Modified Updated: June 26, 2013 April 24, 2008 January 4, 1999 February 3, 1994 October 28, 1993 PROCESS DESCRIPTIONS: Some mineral product industry quarry locations require rock drilling and blasting to loosen desired aggregate deposits.
