Blasting- Highly Technical Prescribed and Scientific Process
Blasting is a highly technical, prescribed and scientific process. To remove the maximum amount of rock with minimal impact, and to ensure the blast's reliability and predictability, there are a number of steps that must be taken. These include the sequencing and timing of a blast and analyzing the physical properties of the source material ...

Rock Quarry Blasting Home Damage Lawsuits
Proving Quarry Blasting Caused Damage to Your Home or Business. When the quarries are blasted with explosives to break up the rock, some energy from the blasts escapes into the atmosphere. This generates air-blasts or vibrations. Repeated exposure to these vibrations creates damage to structures near the quarry.

LCA analysis and comparison in quarrying: Drill and blast vs …
The PM2.5, PM10 and TSP emissions increased by 230%, 229% and 345%, respectively, when using blasting instead of blast-free quarrying. In contrast, the CO 2, CO, NO X and SO X emissions were reduced by 26%, 78%, 73% and 75%, respectively, using explosives. Table 4 includes the outcomes using the NPI (2012) approach.

The Environmental Impact of Asphalt Plants
A 2001 study2 compared emissions from an asphalt plant to emissions from other common community and industrial sources.

Dust emission from crushing of hard rock aggregates
All processes of aggregate production are potential sources of dust emission. Dust constitutes a major environmental concern in many quarries, with crushing suggested as the most significant source of it (Bada et al., 2013; Petavratzi et al., 2005; Sairanen et al., 2018). Dust from drilling has been previously examined in two natural stone ...

Air-Decking and the Environment | Agg-Net
As a practical example, a quarry producing 1 million tonnes of rock per year, using ANFO with a blast ratio (BR) of 7 tonnes/kg, would require 143 tonnes of ANFO, producing around 25 tonnes of CO2. However, if the BR was at the lower end, eg 4 tonnes/kg, that would require 250 tonnes of ANFO, producing some 44 tonnes of CO2, a …

After-Blast Fumes From ANFO Mixtures | Agg-Net
The key actions that can be taken to minimize the production of toxic after-blast fumes from ANFO are: Only use ammonium nitrate prills that are designed for ex-plosive manufacture, ie capable of absorbing 5.6% diesel. Add the correct amount of diesel fuel to achieve an oxygen-balanced mixture.

Dangers of Toxic Fumes from Blasting
Emulsion blasting agents are water resistant and may be loaded in bulk in wet boreholes. ANFO/emulsion blends exhibit water resistance to varying degrees depending on the ratio of ANFO to emulsion. The explosive supplier can recommend a mix ratio that is appropriate for a given application. 2. Determine where the blasting fumes are likely to go.

Emissions from the Crushed Granite Industry State of the Art
The major dust emission control method is the application of water to the haul roads from the quarry area to the plant. The quarry operations and the primary crushing take place in a pit and hence are only minor contributors to the overall plant emis- sions. The major contributor is the secondary crushing and screening unit.
