  • Optimized design of drilling and blasting operations in

    In this paper, a hypothetical open pit copper mine is considered, which needs to produce 30 million tonnes of waste and 25 million tonnes of ore based on its annual planning. This mine works 340 days a year, on which the drilling and blasting operations can be carried out. Thus, the time scale of the dynamic model is set as these operational days.Blasting Drilling of Open Pit Mining Hardrockdrills,Oct 23, 2018· Blasting Drilling of Open Pit Mining.

Karimi Nasab Mining Engineering Department, Shahid Bahonar University, Kennan, IranOpen-pit mining Wikipedia,Open-pit, open-cast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining.Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface.

Bench blasting is normally carried out as short delay blasting. The firing pattern has to be designed so that each blasthole has free breakage. The firing sequence of a chevron pattern can radically alter the drilled burden and spacing into the blasted or effective burden (Be)
