2010 8 26 Mining Optimization Laboratory MOL University of Alberta, Edmonton, Canada . Abstract Long term mine scheduling is among one of the optimization problems. Block caving technique is a mass mining method in which gravity is used in combinationwith internal rock stresses to fracture and break the rock mass into pieces that can be handled by miners.
With a design ore production capacity of 12.5 million tonnes per year, the Pulang copper mine is China's second largest block caving mine. It is located 63 km northeast of the city of Shangri La in Yunnan Province. The orebody outcrop has an altitude of 3,868 4,023 metres above sea level masl and its bottom is below 3,500 masl.

In mining: Mining massive deposits. for such deposits is called panel/block caving. It is used under the following conditions: 1 large ore bodies of steep dip, 2 massive ore bodies of large vertical extension, 3 rock that will cave and break into manageable fragments, and 4 surface that permits subsidence.

2013 2 2 This is an important potential long term impact, and needs to be carefully researched and addressed. Block caving will most likely cause surface subsidence, and because the Pebble deposit is a sulfide deposit, the
2022 7 6 The C Zone block cave zone is around 550 m below Lift 1. Development towards the C zone is underway with production planned to commence with the first of 143 planned drawbells in the second half of 2023.
The most viable way to recover the ore body is by a well established underground mining method called block caving. Block caving is safe, environmentally sound, and cost effective for mining a large, deep orebody. In block caving, a large section of ore is initially undercut by drilling and blasting, causing it to collapse under its weight.
