عرض المزيدThe drill and blast process is one area where considerable benefits can be gained. Design accuracy. Firstly the design of the pit should be examined. How the material is to be moved and what equipment moves it, needs to be understood. A strip mine operation may utilise throw or cast blasts where the blast moves the material into the adjacent strip. This means the dragline or digging equipment ...

عرض المزيدIntroduction – Drill and Blast. The operations of drilling and blasting are critical to mining operations. The safety of a blast, the quality of the material fragmentation, the roads'' conditions, and the resulting slope stability all strongly depend on the proper execution of these jobs. The drilling itself can be treated as an activity composed of several steps and begins long before the drill rig even reaches the workbench.
