H BLASTING IN SURFACE EXCAVATION1 BLASTING IN SURFACE EXCAVATION Any blast optimisation programme calls for a clear understanding of the effects of principal blast parameters and their careful application. The degree of fragmentation of rock depends on: a. the rock's characteristics; b. the properties and quantities of explosives; c. blast geometry; d. blast size; e. the priming method; and f.
Drilling 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, tunnel or road construction. The result of rock blasting is .
Controlled Blasting Techniques In Granite Quarry. Extraction of marble blocks by controlled blasting techniques - a case study the successful water-coupling cutting blasting practice in the granite quarry has great potential to be applied in.
As a quarry blasting technique the Royex rock breaking system can be used both as a primary and secondary blast or rock breaking alternative. Since the system is very precise and causes minimal rock vibrations and fly rocks, drilling and blasting operations can be done simultaneously.

In normal blasting all holes do not blast at the same time. Bench blasting is normally carried out as short delay blasting. The firing pattern has to be designed so that each blasthole has free breakage. The firing sequence of a chevron pattern can radically alter the drilled burden and spacing into the blasted or effective burden (Be)

Oct 12, 2012· In these cases, the firing pattern can be used to control the blast direction in a more favourable direction and improve the blasting result. Before drilling, the blast direction should be set according to the orientation of the main jointing systems. Fragmentation, backbreak and toe problems are all dependent upon the blasting direction.
Noise from rock blasting and other quarry operations are responsible for loss of biodiversity particularly birds. Soil samples were collected at depths 0-15 and 15-30 cm from the three quarry sites and from a control, 1 km off the quarry sites, against the direction of drainage. Water sample was also collected from an abandoned
