wall control blasting in open pits

Wall Control Blasting in Open Pits, The best approach is to control blasting effects so the inherent strength of pit walls is not destroyed Presplit and trim blasting are two control blasting techniques used to accomplish this Both techniques are designed to create a low explosive energy concentration per unit of wall area at the perimeter of the pitFull page fax print, break-control blasting techniques reduces not only the quantity of rock to bc removed it lessens the hazard and cost of rockfalls , A cushion blast is a pit-wall blast in which back-row blastholes contain lighter charges and are drilled in a correspondingly smaller pattern (Figure 132) The diameter ofCase Study Wall Control Improvement, includes measurement and fragmentation control with advanced modelling and wall quality evaluation through KPI, with the technical support and products that support the Wall Control technology To control the instability the first priority is bench quality improvement, carrying out: Redesign of Drill and Blast parametersosmregov, osmregovPPT, Final Wall Stability in Metal Open Pit Mines Using Presplit Blasting An Image/Link below is provided (as is) to download presentation Download Policy: Content on the Website is provided to you AS IS for your information and personal use and may not be sold / licensed / shared on other websites without getting consent from its author.
