Design of PM2.5 monitoring and forecasting system for opencast coal

The dust produced by transportation roads is the primary source of PM2.5 pollution in opencast coal mines. However, China's opencast coal mines lack an efficient A total of 1772 surface soil samples were collected, and the concentrations of eight major HMs were determined. The HM concentrations in this study were relatively lower than the Heavy metal concentrations of soils near the large opencast coal mine

Characterization of different road dusts in opencast coal mining

Observing the overall generation and characteristics of coal dust, it is suggested that coal dust from haul and transport roads of mining areas can be effectively collected and used as domestic fuel. Dust from haul and transport roads are the major source of air pollution in opencast coal mining areas. Dust generated during mining Recently, large-scale opencast mining activities in India have led not only to the increased generation of large volumes of overburden (OB) dump materials, but also to the transportation of huge volumes of loose geo-materials from coal faces to areas specifically designated for storing these materials in the form of external or internal Characterisation of overburden dump materials: a case study

Design of Haul Roads in Open Cast Mines in India—A

Dump materials as well as interface material, layer of crushed coal, waste rock at the base of the dragline dump are collected from the existing dragline dump of different mines. Dump and interface materials are compacted in the laboratory duly collected from 11 opencast mines of NCL as per principles of equivalent material modelling forSince, different capacities of dump trucks operate in surface mines to transport material from shovels to crushers or dumping points, the specific fuel consumption (SFC) is a good performance index for benchmarking.

Life cycle assessment of opencast coal mine production: a

Coal mining is one of the core industries and plays a positive role in the economic development of some countries (Masto et al. 2015).Coal provides 75% of primary energy requirements in South Africa (Mangena and Brent 2006).Coal is also an important raw material source of energy in China and has a significant strategic position in national Opencast mining is a mining technique of extracting minerals from the near-surface layer of earth, these raw materials can be then used for further processing, for example, in production of metals or buil-ding materials. Our product portfolio ranges from mining equipment (e.g., excavators) to crushers, belt conveyors and subsequent stackingOPENCAST MINING SOLUTIONS FOR THE GLOBAL

Online coal dust suppression system for opencast coal mines

India is the second largest producer of coal in the world. Coal India Limited, the state-owned coal mining corporate is the single largest coal producer in the world. It has 352 coal mines of which 158 are underground, 174 are opencast and 20 are mixed mines (Coal India Limited 2023). Most of the dust suppression sprinklers in these Air pollution in opencast coal mine areas is a critical issue, resulting in harmful severe effects on human health. Therefore, it is essential to understand the air pollution factors and to assess the risks to humans. This study evaluated the potential risks (carcinogen and non-carcinogen) of inhalation exposure to PM10-bound heavy metals Human health risk assessment of PM10-bound heavy metals

An approach to quantify heavy metals and their source

Mining activities in the opencast coal mines contaminate the surrounding soil by releasing coal dust containing heavy metals (HMs). The objective of the present study was to quantify the concentration of HMs like Fe, Cu, Mn, Ni, Cr, Zn, and Co in soil on profile and distance basis in the vicinity of the coal mines. This research also proposed the coal mine construction in China, the research and development, manufacture and control of opencast coal mine equipment has developed rapidly.

INNOVATIONS OF DEEP OPENCAST MINING WITH

The Coal vision 2025 of India estimates that the total domestic coal production is projected to increase to 1086 MT in 2025, of which the opencast production will be 902 MT (83%). In India miningAs a result, all the opencast mines have directly or indirectly are contributing to the air pollution. Even the associated activities of opencast mines such as unloading and loading of coal, transportation of coal, poor condition of roads, and huge quantities of open air coal burning by the villagers are the causes responsible for air pollution.Coal Mining and Local Environment: A Study in Talcher
