  • blast hole drilling: the basicprocess|rpm drilling

    Blast hole drilling is traditionally used wherever the mining company wants to explore the mineral composition or potential mineral yield of the area demarcated for their mining interests. Blast holes are thus a fundamental step in the exploratory mining process, and can be employed in both surface mining operations and underground mining operations to varying degrees with varying effects or results. Blast …

    6th May 2020 Jon Lawson. Mining is a hugely energy-intensive business. The drill and blast part of the process is very important in so far as how it influences other downstream processes. For example, the Coalition for Eco Efficient Comminution (CEEC) group of industry experts has recently compiled some thought-provoking figures

    The typical cycle of excavation by blasting is performed in the following steps: Drilling blast holes and loading them with explosives. Detonating the blast, followed by ventilation to remove blast fumes. Removal of the blasted rock (mucking). Scaling crown and walls to remove loosened pieces of rock

  • an integrated approach to the drill and blast process

    Aug 12, 2020 · Like many catchy mining phrases, “Drill to Mill,” “Pit to Plant,” “Mine to Mill” and “Mine to Market” are deceptively simple descriptions for complex, multi-layered processes. In the mining cycle, drill and blast (D&B) is arguably the first and most important step to get right. D&B operations impact the entire mining process, from mining equipment efficiency, through crushing and grinding circuit …

  • drilling and blasting | technical aspects of mining

    1. Drilling and blasting. By far the bulk of rock excavated in mining globally is broken by drilling and blasting. Mining is the largest consumer of civil explosives. Mining explosives are substances which detonate to produce a high-intensity shock wave and large volumes of gas which, being confined in a hole, expand rapidly, entering existing minor cracks in the rock, and creating new cracks to break the …

    Blast hole drilling is a continuous process and blasting is done once a day, typically in the early afternoons between 12h00 and 14h00, at each of the active mining areas within the mine pit. In 2007, Sishen Mine and Khumani Mine received DMR approval to mine the boundary pillar between the Sishen and Khumani mine pits
