There are essentially two types of solution mining: 1) insitu and 2) inplace. Inplace solution mining requires permeability enhancement techniques such as blasting or previous mining activities ( blockcaving) to fragment or increase the permeability of the rock prior to applying a leaching solution to liberate ore from the surrounding ore body.
The New Mine Level Project is a 130 000 tonnes per day (tpd) panel caving project set to start in 2017. The high stresses, complex structural setting and high mining rates present major challenges
#0183;#32;As compared to other mining methods, sublevel caving allows for a quicker and less expensive mining process. However, sublevel caving leads to greater dilution and is therefore used for lower ore bodies. The costs for sublevel caving range from 58/tonne. Block Caving. Block caving is the logical stepup of sublevel caving.
Block caving relies on fragmentation and forces of gravity to cave an underground orebody to draw points, from where it is collected and taken away for processing. Monitoring the flow of the caved ore was only possible once markers, embedded in the orebody, exited at the draw points at the bottom.

Block caving with a rating of is the most preferred then Square Set Stoping, Top Slicing mining methods (Table 13). Block Caving was the most appropriate on consideration of the 8 factors
stoping, cutandfill, longwall mining, sublevel caving, and block caving. The second section describes underground mining equipment, with particular focus on excavation machinery such as boomheaders, coal cutters, continuous miners and shearers. 1. Underground Mining Methods Classification of Underground Mining Methods
Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight. It is the underground version of open pit mining. In block caving, a large section of rock is undercut, creating an artificial cavern that fills with its own rubble as it collapses.

#0183;#32;Block Caving
There are four main mining methods: underground, open surface (pit), placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
cial barrier blocks 01 and 1 on Level (210)(14) m. Block no. 2 is extracted by caving; block no. 1 is mined with stopes and backfilling. Block no. 1 is mined first. The artificial barrier pillar 54 m wide is formed in the course of mining in levels, with stopes 70 m high, 27 m long and m wide.
CAVE MINING HANDBOOK _____ Page 2 of 138 Chapter 1 INTRODUCTION The object of this handbook is to highlight factors which lead to problems in cave mining and to summarize the contents of the Manual on Block Caving so as to provide a reference on all facets of cave mining.
The Solution. At Snowden, we developed Block Cave Optimisor tool to optimise the footprint and column heights for a cave, considering all these important constraints. First, it applies vertical premixing to gain a more accurate view of mining grades.
Lowest mining cost per ton: Block cave mining operating costs are a fraction in comparison with any other underground mining method. Flexible production rate from cave mining methods : Block cave mining is driven by economies of scale, where production rates can reach up to 100 kilotonnes per day; however, there are smaller mines working successfully with lower production rates such as 15
