Empirical Approach Based Estimation of Charge Factor and
Blasting with the aim to reduce oversize boulders in underground has many hurdles due to limited accessibilities and poor site conditions. Optimized drilling and blasting parameters can help to achieve this objective. The major challenges of the blast designers lie within deciding blast geometry, namely drill hole diameter, burden, and …Web

Reduction of Fragment Size from Mining to Mineral Processing
3.3.1 Drill Plan. A drill plan involves diameter, length, burden, spacing, subdrilling, number, and distribution of boreholes in a blast. The diameter of boreholes can be chosen empirically (e.g., Adhikari 1999). The diameter must be larger than the critical diameter of the explosive to avoid malfunction of the explosive (Zhang 2016a).
