Bme Training Module Presplitting And Wall Control Design To alleviate these hazards, deep hole pre splitting blasting is employed to control periodic fractures in thick hard roof seams in datong mining area. Pre splitting case study free download as pdf file (.pdf), text file (.txt) or read online for free.
Pre Splitting Case Study Pdf The study consisted of using the presplit concept for final crown wall protection from an existing drill design pattern to prevent wings instability after blasting effects . By creating a pre defined fracture line, presplitting protects critical areas, such as final pit walls, from blast induced damage. proper design, including optimized hole spacing, charge distribution, and timing, is essential for achieving effective results. Pre splitting and roof cutting technology is widely used in reducing residual coal pillars and safe pressure relief mining, which has become the crucial technology for pillar free mining methods. Presplitting method was used to protect wall from getting damaged due to production blasting operations at north mara gold mine.
