Rock blasting Research Papers - Academia.edu

Blasting is a process of breaking the rock mass to excavate the ore and materials. Many open blasting operations are faced with the apparently conflicting requirements of providing large quantities of fragmented rock and of minimizing the amount of damage inflicted upon the surrounding slopes.

Dangers of Toxic Fumes from Blasting

blasting agents used in large-scale surface mine blasting do not detonate properly in boreholes of 1-inch diameter or less (ISEE, 1998). If the blasting agent is diluted by mixing with drill cuttings at the top or bottom of the borehole it may not detonate properly and excessive quantities of toxic fumes may be produced (Sapko, 2002).

3. The Environmental Impacts of Aggregate Extraction ...

Aggregate is mined from the earth, either dug out of pits or blasted out of quarries. This process has many significant environmental impacts. [1] Creating the pits or quarries requires the removal of virtually all natural vegetation, top soil and subsoil to reach the aggregate underneath. Not only does this lead to a loss of existing animal ...

11.19.1 Sand And Gravel Processing

Industrial sand and gravel typically are mined from open pits of naturally occurring quartz-rich sand and sandstone. Mining methods depend primarily on the degree of cementation of the rock. In some deposits, blasting is required to loosen the material prior to processing. The material may

Blast-Casting Mechanism and Parameter Optimization of a ...

Specifically speaking, once the blast-casting technique is applied in opencast coal mines for overburden removal, 30–65% of the materials can be directly thrown into the mined-out area without any need for further handling (Figure 1); thus, it will reduce the stripping cost by more than 30% [1, 2]. As a matter of fact, blast-casting is the ...
