How would you describe cut and fill mining?

Cut and fill mining is a highly selective open-stope mining method considered ideal for steeply dipping high grade deposits found in weak host rock. In this method, mining begins at the bottom of the ore body or block and progresses upward.

What is stoping mining method?

Stoping, in mining engineering, the opening of large underground rooms, or stopes, by the excavation of ore. Stoping is practiced in underground mineral mining when the surrounding rock is strong enough to permit the drilling, blasting, and removal of ore without caving.

What is drift fill mining?

Drift and fill is similar to cut and fill, except that it is used in ore zones, which are wider than the method of drifting will allow to be mined. In this case, the first drift is developed in the ore, and is backfilled using consolidated fill. The stope is emptied when all of the ore has been blasted.

Under what condition you shall work Mechanised cut and fill stope with captive machines?

Mechanized cut and fill mining refers to cut and fill stopes that are accessible by rubber tired equipment from the regular mine access development. Mechanized cut and fill stopes can be very productive with stope widths in excess of 40 m in good ground conditions and stope lift heights of 4 to 8 metres.

When should I cut and fill?

Cutting and filling is the process of moving earth from one place to another to make ground more level. A ‘cut’ is made when earth is cut from above the desired ground height and a ‘fill’ is when earth is used to fill a hole to desired ground level.

What are the methods of mining?

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits.

What are the stages of mining?

The 5 Stages of the Mining Life Cycle

• Exploration and prospecting. The beginning of any mining project begins with the exploration stage; it’s where the magic happens.
• Mine-site design and planning.
• Construction.
• Production.
• Closure and reclamation.

What are the pros and cons of underground mining?

So, in these cases underground mining is more cost effective. The downside is that human health and safety are at greater risk from mine cave-ins, flooding from groundwater or sea water, methane explosions in coal mines, or failure of air ventilation equipment.

How is solution mining done?

Solution mining refers to the production of salt (or potash, or other soluble products) by pumping water into subterranean salt deposits, found in many parts of the world, dissolving the salts and pumping the brine to the surface for drying and further use.

Is cut and fill expensive?

Costs. Builders say that putting a concrete slab on a cut and fill site is cheap, and it is until you factor in extra costs to solve the drainage problems that occur after the builder has long gone. Putting in drainage after completion of the home is very expensive.

How do you determine cut and fill?

The cut or fill depth for each cell is found by subtracting the average existing level of the cell from the average proposed level. If the resultant depth is positive then this is a fill cell, while a negative value indicates a cut cell.

What are 4 types of mining?

There are four main mining methods: underground, open surface (pit), placer, and in-situ 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.

How is cut and fill stoping used in underground mining?

Cut and fill stoping is a method of underground mining used in vertical stopes and in mining high-grade irregular ore bodies. The rock mass surrounding the ore deposit is also usually weak unable to support loads over an extended stoping height.

When do you use cut and fill stoping?

Cut and Fill Stoping. Cut and fill stoping is a method of underground mining used in vertical stopes and in mining high-grade irregular ore bodies. The rock mass surrounding the ore deposit is also usually weak unable to support loads over an extended stoping height.

When to use an open stoping mining method?

Open stoping is applicable to deposits of strong, firm ore having strong, firm walls. In the narrower deposits (30 to 50 feet wide) the ore often can be mined the full width in one operation without the use of pillars.

What kind of equipment is used for cut and fill?

The geometry of the ore body dictates the size and type of such equipment including slushers, drills, and LHD’s. Cut and fill operations with large stope geometry may permit the use of drill jumbos and large LDH equipment whereas smaller stopes may preclude the use of stopper drills and smaller LHD’s.
