·The belt conveyor is the most commonly used conveying equipment in the coal mining industry As the core part of the conveyor the belt is vulnerable to various failures such as scratches cracks wear and tear Inspection and defect detection is essential for conveyor belts both in academic research and industrial applications
·A state of the art assessment was carried out as well as a case study applied to a large iron ore mine located in Brazil The main advantages identified in the use of conveyor belts were the lower exposure to the risk of accidents and the ability to overcome high angles On the other hand trucks had high operating flexibility and lower Capex
An important and very attractive feature is the ability to suspend the conveyor from the roof in an underground mine as shown in Fig 2 leaving more room for improved housekeeping and allowing passage of face service equipment haulage vehicles and other mining equipment The conveyor s open construction allows quick and easy visual
2 ·Advantages of Using Coal Energy Coal has been a massive contributor to our lives With its practical uses it has managed to create a benchmark in many spaces Coal mining is a big business that is majorly labor intensive Hence unlike other energy sources it creates several job opportunities for drivers miners cleaners loaders
In surface mining the ground covering the coal seam the overburden is first removed to expose the coal seam for extraction The elements of a surface mining operation are 1 topsoil removal and storage for later use 2 drilling and blasting the strata overlying the coal seam 3 loading and transporting this fragmented overburden material called spoil 4 drilling and blasting the
The coal flow of the belt conveyor will be mixed with anchor rod angle iron wood gangue and lump coal This will easily lead to the tearing of the conveyor belt the blockage of the transition and even the breakage of the belt It is difficult for the inspection robot of the belt conveyor to efficiently and accurately recognize foreign objects in the environment of uneven lighting and
·Coal has been a backbone of past and present economies Currently coal is the largest source of electricity generation and the second largest source of primary energy in the world IEA 2021a While coal fired electricity generation has declined in 2019 and 2020 mainly due to the COVID 19 pandemic and fluctuations in gas prices the growing electricity demand
·Fully mechanized mining FMM technology has been applied in Chinese coal mines for more than 40 years At present the output of a FMM face has reached 10 million tons with Chinese made equipment In this study the new developments in FMM technology and equipment in Chinese coal mines during past decades are introduced The automatic FMM
