The increasing size of loaders and haulers in both surface and underground mines has increased productivity. Technology Needs In simple terms mining involves breaking in-situ materials and hauling the broken materials out of the mine, while ensuring the health and safety of miners and the economic viability of the operation.
Open stopes, room-and-pillar, and sublevel stoping methods are the most common unsupported methods; cut-and-fill stoping when the fill is often waste from the mine and mill tailings is the most common method of supported underground mining Figure The shearer is much like a cheese slicer running back and forth across a block of cheese.
To increase productivity a truly continuous haulage system will have to advance with the advancing cutter-loader. The fallout from these changes is often unexpected. This method is commonly used in places where the topography and the deposit are generally flat.
Establishing and adopting better engineering approaches, analytical methods, and design methodologies, along with the other characterization technologies described above, would considerably reduce risks from ground-control failures and provide a safer working environment.
Transporting ore for processing can take considerable time and energy and can contribute significantly to the overall cost of production in both surface and underground mining operations.
The conveyor discharges the coal onto a conveyor belt for transport out of the mine. Kennecott Utah Copper Corporation.
Underground coal mining today is basically done by two methods: For this purpose the development of ore-grade analyzers to quantify the metal and mineral contents in the rock faces would be extremely useful.
On the other hand, the manufacturing and eventual disposal of new types of batteries or fuel could have environmental impacts. Evolutionary and Revolutionary Technologies for Mining. Advances in in-ground geophysics could lead to the development of new technologies for predicting geological conditions in advance of the mining face defined here as look-ahead technology.
The drawback is that the savings come at the cost of customer satisfaction. Ongoing work could be leveraged and extended to meet the needs of the mining industry.
Market share made it conservative, more concerned with maintaining its success than meeting new challenges. The environmental risks associated with in-situ mine-bed preparation by injection of explosives or other means of creating permeability will have to be evaluated.
All three areas should be pursued in parallel to effect progress in the development of a usable system. Early focus of this research should be on a better understanding of fracture mechanisms in rock so that better cutters can be designed NRC, b. Wikis and other sources of online information can help customers without assigning a staff person to explain things.
Geological problems encountered in mining can include local thinning or thickening of the deposit, the loss of the deposit itself, unexpected dikes and faults, and intersections of gas and water reservoirs.
In recent decades another driver has been a growing awareness of the adverse environmental and ecological impacts of mining. Because of the high costs associated with supported and unsupported mining methods, open stoping with caving methods is used whenever feasible. The third area of need is data display and visualization, which are closely related to the processing and interpretation of data.
The ore-grade analyzer must have both real-time analysis and communication capability so operations could be adjusted. Ground Control The planning and design of virtually all elements of a mining system—openings, roadways, pillars, supports, mining method, sequence of extraction, and equipment—are dictated by the geological and geotechnical characterization of the mine site.
New methods of explosive tailoring and timing would also have significant benefits. These failures often result in loss of lives, equipment, and in some cases large portions of the reserves.
Materials Handling The design and proper operation of clearance systems for transporting mined materials from the point of mining to processing locations are critical for enhancing production. Embracing the latest staff-cutting tech can leave customers with a negative view of your company.
Research could focus on powering heavy equipment with alternative energy sources, such as new-generation battery technology, compressed air, or novel fuel-cell technology.
However, larger equipment is associated with several health and safety hazards from reduced operator visibility. Electric equipment has similar disadvantages, even though it is cleaner and requires less ventilation, because power transmission and cabling for highly mobile equipment complicates operations.
