In this study, based on the Changjiu Shenshan limestone aggregate mining project in China, large-scale blasting experiments were conducted to investigate the influence of rock properties and blasting parameters on the size distribution of post-blast fragments and fines content.
Blasting plays a key role in mining operations, and its results can directly affect downstream operations, including crushing and milling. Therefore, predicting a blast performance helps engineers control blast fragmentation and control and minimize negative effects of blasting like ground vibration and flyrock.
Blasting plays an important role in mining and quarrying operations, primarily serving to break down hard rock formations into smaller, manageable pieces. This process is crucial for accessing valuable minerals, ores, or aggregates embedded deep within the earth. By utilizing controlled explosions, miners fracture rock masses, facilitating ...
