A Short Note on Surface Miner




 Surface miner 

It is a Continuous surface mining machine which is used in coal mines, lime stone mines and also in sand stone this machine is made by wirgton, takaraf, and vovest alpine company.


 Applicability 

1. It is applicable where the strength of materials is from 12 to 50 Mpa
2. It can be operate 2.5 cm thin coal seam or other bedded deposits and climbing inclination not greater than 15".
3. It can be used in flat surface not hilly terrains.
4. This machine is very effective developed areas where drilling and blasting is prohibited.

 Advantages 

1. Selective mining is possible..
2. Better exploitation due to lower mining cost.
3. Lower processing cost because the coal doesn't need pass through the beneficiary small plant.

 Production 

Q = Vm x h x b x 60 m ^ 3/h
Q = Quantity cut, (m ^ 3) / h
Vm= Machine speed, m/min.
h = Milling depth, m
b = Milling drum width, m

How to Calculate the Bench Width in a Mine

Image
Bench design plays a crucial role in the stability, safety, and productivity of open-pit mining operations. Bench width is an important factor when planning the excavation and haulage activities in open-pit mines. Proper bench dimensions help maximize ore recovery, provide safe working conditions, and optimize equipment usage. This article will offer a detailed explanation of how to calculate the bench width in mines, using a real-world scenario to demonstrate the calculations. We'll also cover the factors that affect bench width and provide an SEO-optimized guide for those looking to rank this article on Google.  What is Bench Width?  In open-pit mining, a "bench" refers to the step or ledge formed during the process of extracting material from a surface mine. A bench is created when layers of overburden and ore are excavated at specific heights. The bench width is the horizontal distance between two consecutive benches (also known as bench-to-bench distance). Bench widt...

Slope Stability in Mines: Prevention and Mitigation Strategies

Introduction Slope stability is a critical concern in mining operations. The failure of slopes can lead to significant economic losses, environmental damage, and, most importantly, endanger human lives. Effective slope stability management requires a comprehensive approach that combines geological, geotechnical, and engineering principles. This report delves into various methods for preventing slope instability in mines, including analytical techniques and before-and-after comparison data. Factors Affecting Slope Stability Several factors can influence the stability of a mine slope, including: Geological Conditions: Rock type, structure, and weathering patterns. Different rock types exhibit varying strengths and resistances to deformation. Faults, joints, and other discontinuities can weaken the rock mass, making it more susceptible to failure. Weathering processes, such as erosion and chemical alteration, can also degrade the strength of rock. Geotechnical Properties: Strength, st...

How surveying is done in a Mining site (Methods)

  Surveying is a critical element in the mining industry, playing an essential role in the development, operation, and closure of mining sites. It provides accurate, detailed information about the topography, boundaries, and geology of the mining area, allowing operators to plan and execute mining activities efficiently. This article aims to offer a comprehensive overview of surveying in mining, discussing various methods, processes, and the advantages and disadvantages of each approach.  What is Surveying in Mining?  Surveying in mining involves the collection of data related to the physical characteristics of a mining site. This data is vital for planning and executing operations such as exploration, drilling, blasting, excavation, and transportation. Accurate surveying helps mining companies determine the volume of material to be extracted, identify potential hazards, optimize workflows, and ensure that operations comply with regulatory guidelines. Surveyors use advanc...
