How to optimize dust pollution control in opencast coal
Introduction. Coal is the key energy source for industrial development. For a long time, China’s economic and social development has had a strong demand for coal, and the coal industry has developed rapidly [1, 2].Compared with other types of mines, opencast mines have higher safety levels, higher coal recovery rates, larger production Design of Haul Road Illumination System for an Opencast Coal Mining Project—A Case Study January 2014 LEUKOS The Journal of the Illuminating Engineering Society of North America Chowdhury(PDF) Study of Illumination System in Open Cast

3.6.4 Losses During Mining. Mining of coal is undertaken broadly using two methods: surface and underground. In the case of underground mining, losses are high compared with those of opencast mining; the main causes of these losses are enumerated in the following subsections. 3.6.4.1. Opencast MiningCont. iv) Coal Extraction Coal mining may be by : A single bench or two depending on thickness or quality of the coal seam. E.g at wankie colliery in Zimbabwe a 10 m thick seam is mined in two benches because the top 5 m is power coal and the bottom 5 m is coking coal. The main equipment here is the power shovel.Open-Cast Mining Method PDF Coal Mining Construction Equipment

Prediction of road dust concentration in open-pit coal mines
The problem of dust pollution in the open-pit coal mine significantly impacts the health of staff, the regular operation of mining work, and the surrounding environment. At the same time, the open-pit road is the largest dust source. Therefore, it analyzes the influencing factors of road dust concentration in the open-pit coal mine. It is of practical Mining and Mineral Processing 3.1 Opencast Mines Opencast mining is extraction of commercial minerals from the Earth’s surface using open-pit workings. About 60 % of metallic ores, 85 % of non-metallic ores, 100 % of non-metallics, and 35 % of coal are produced by this method. The distribution of mineral resources of the world is shown Chapter 3 Mining and Mineral Processing Springer

(PDF) OPENCAST COAL MINING AT LARGE DEPTH IN INDIA
R.N. Gupta. In Indian coal mining industry, most of the operations are restricted to single seam workings. Past indiscriminate practices have sterelised large amount of coal in multiple seamsChina has the largest coal production in the world due to abundant resource requirements for economic development. In recent years, the proportion of opencast coal mine production has increased significantly in China. Opencast coal mining can lead to a large number of environmental problems, including air pollution, water pollution, and solid Life cycle assessment of opencast coal mine production: a

Open Pit Mining IntechOpen
Open pit mining method is one of the surface mining methods that has a traditional cone-shaped excavation and is usually employed to exploit a near-surface, nonselective and low-grade zones deposits. It often results in high productivity and requires large capital investments, low operating costs, and good safety conditions. The main 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 Characterization of different road dusts in opencast coal mining
