  • Chapter 8 BLAST DESIGN

    The economic analysis of the use of explosives is an important part of blasting operations in mining and construction. Explosives are energy, and the efficient use of this energy is a major factor in keeping rock blasting costs under control. High-energy explosives enhance fragmentation, which ultimately produces a positive effect on production costs.

    The blast hole size is the first consideration of any blast design. The blast hole diameter, along with the type of explosive being used and the type of rock being blasted, determines the burden (distance from the blast hole to the nearest free face). All other blast dimensions are a function of the burden.

  • What Are the Disadvantages of Opencast Mining

    Full Answer. Rock blasting creates fractures in the rock, allowing mine drainage leakage from abandoned mines into groundwater aquifers. Contaminated groundwater typically has a higher pH and total hardness, and contains dissolved sulfate. Radioactive elements produced from rock slurries can also pollute groundwater by leaking into fractured bedrock.
