Development mining is largely in the orebody, and trackless equipment can be used to enhance the production capability. On the other hand, the necessity of leaving pillars leads to a low recovery ratio. Therefore, there is more ore loss when mining under high ground pressure because more and larger pillars are needed. Breast stoping: it is an open stoping method often used for mining gently
Underground Mining Underground mining isplex and more expensive than open pit mining. Where removing the overburden would be too costly or ineffective to reach the ore, the decision is made to go underground. Decline tunnels, known as ramps are constructed to access the orebody.

The grades or quality of the orebody are high enough to cover costs. Underground mining has a lower ground footprint than open pit mining. What is underground mining? The underground mining methods we use include room and pillar, narrow vein stoping and large scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive
12.4 Underground mining method Room and pillar mining Normally applied in flat lying stratiform or lenticular orebodies admitting an orebody dip up to about 30°. Rooms serve the multiple roles as ore source, access opening, transport drift, and airway. Pillars are normally arranged in a regular grid array to simplify planning, design and operation. Pillars may be permanently unmined or
Cave mining refers to all mining operations where the orebody caves naturally after undercutting and the fragmented material is recovered through drawpoints. Cave mining has the lowest cost for underground mining, provided the drawpoint size and handling facilities are appropriate for the caved material in a given mine Laubscher, 1994.
Underground Mining Operation Where the orebody is located underground at depth and requires a decline to be used. In Hardrock mining autonomous loaders boggers have been driving themselves around levels since 2006, however still require an operator to fill the bucket with rock. These are the remote bogger operator jobs you see everywhere on seek. This is

The orebody The underground orebody has been identified as a massive rectangle of approximately 600 000 m2. This is divided into four macro blocks, 200 to 250 m high. The orebody runs eastwest and has a near vertical dip.
The grades or quality of the orebody are high enough to cover costs. Underground mining has a lower ground footprint than open pit mining. What is underground mining? The underground mining methods we use include room and pillar, narrow vein stoping and large scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive
Once a decision has been made to go underground, the specific mining method selected depends on the size, shape, and orientation of the ore body, the grade of mineralization, the strength of the rock materials, and the depths involved. For example, if the ore is very high grade or carries a high price, then a higher cost method can be used.

Orebody modeling is the geological basis of your mine planning. SGS has the geologists and engineers to help develop the modeling program that is right for your project. These professionals have extensive experience developing models and evaluation procedures.
James Walchuk, manager of Bulys mining group, is equally impressed. The two biggest surprises, after the orebody, are the ability to work in Tanzania and the achievement of the underground crews. Even so, with grades concentrated in a narrow portion of the mining widths, selective mining must be exactly that
Sub level caving is an effective mining method for steep orebodies, allowing maximum extraction from the orebody with a high degree of safety. LKAB places great emphasis on refining every element of the underground mining process, in order to make it as efficient as possible. From the Kiruna mine alone, more than 75,000 tonnes of iron ore are mined per day, which is
Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually containing metals such as ore containing gold, silver copper etc. The mining method selected is determined by the size, shape, orientation and type of orebody to be mined.

There are two principal phases of underground mining: development mining and production mining.
Development miningposed of excavation almost entirely in non valuable waste rock in order to gain access to the orebody. There are six steps in development mining: remove previously blasted material muck out round, scaling removing any unstable slabs of rock hanging from the roof and sidewalls to protect workers and equipment from damage, installing support or/and reinforcement using

Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mininges prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on
Many underground mining methods rely on blasted rock moving under gravity to report to extraction points. Mining of orebodies dipping between 20 45 degrees poses a unique challenge for mining engineers in that a dip angle in this range will not allow the movement of broken ore down the footwall to the mucking horizon utilising gravity.
