Wardha Valley Coalfield (WVC) is a NW–SE elongated structural basin with its coal bearing zone spreading over an area of 800 sq km along a length of 116 km situated towards the south of the city of Nagpur in the central region of India (Fig. 1).This coalfield has around 40 opencast coal mines, which are largely of medium scale type with …
Opencast mining dominates coal production in India and a survey was conducted to evaluate its local atmospheric impact, revealing high pollution potential due to suspended particulate matter and consequent impact on human health. Opencast mining dominates coal production in India. A survey was conducted to evaluate its local atmospheric …
Thus, the behaviour of opencast mines (physical, chemical and biological) is inextricably linked with the hydrology of the catchment as initial behaviour of the catchment is completely changed by them (Choubey and Rawat 1991). Jharia is one of the largest coal fields in India covering about 460 km 2 of area. Opencast and
With the advent of mining activities at Raniganj coalfield in India, the natural topography has been defaced in some elongated tracts by either excavation or dumping. This paper deals with opencast mining induced defaced topography of Raniganj coalfield, which needs to be reclaimed properly right after mining. This paper …
In India, coal mining is conducted using two methods: underground and opencast methods. The underground method is suitable for extraction of deeper coal seams, whereas opencast method is suitable for shallow …
Surface mining is the dominant driver of land use land cover (LULC) change in the Raniganj coalfield region in West Bengal, India. Owing to its multifaceted consequences on soil, water, and ...
It lies between 23°09′ to 23°12′ N-latitude and 82°19′ to 82°22′ E-longitude. A pilot study was undertaken in representative open cast mine area of about 0.80 km 2, which is 12.3% of the total area (6.49 km 2) under opencast mines of Chirimiri. The exact location of study site is depicted in Fig. 1. The climate of the study area is ...

Slope stability analysis forms an integral part of the opencast mining operations during the life cycle of the project. In Indian mining conditions, slope design guidelines were not yet formulated for different types of mining practices and there is a growing need to develop such guidelines for maintaining safety and productivity.
Coal is a major source of nonrenewable energy in India. Most of the Industries depend on the coal to meet the energy demand of the country. ... Opencast mining of coal is contributed to 93.31 % o ...
Abstract. Opencast mining dominates coal production in India. A survey was conducted to evaluate its local atmospheric impact. Emissions data were utilised to compute dust generation due to different mining activities. Work zone air quality, ambient air quality and seasonal variations are described revealing high pollution potential due to ...
In India, coal mining is conducted using two methods: underground and opencast methods. The underground method is suitable for extraction of deeper coal …
With growing demand for mineral resources and favourable policy towards the mining sector, developing countries have become investment hubs for mineral extraction, which has changed the socioeconomic and ecological scenarios particularly in rural areas. Extractive industries such as coal mining generate negative externalities …
This paper presents the analysis of large mining machinery related accidents in Indian opencast coal mines. The trends of coal production, share of mining methods in production, machinery deployment in open cast mines, size and population of machinery, accidents due to machinery, types and causes of accidents have been analysed from …
A general pattern of the lay-out for open casting, whether it is below ground level or above ground level, is to form benches or stepped working-faces. Opencast mining in India is practiced in manganese-ore mining in Madhya Pradesh and the overburden benches are 30 ft (9 meters) high. Blast-hole drilling is employed and power shovels are used ...
A total of 158 UG mines of CIL produce 25mt fuel at an average of 1.6 lakh tonne a mine a year. In FY23, output per manshift (OMS) in CIL was 16 tonne in opencast and only 1.05 tonne in ...
