2021-3-30 Abstract: In many circles, brown coal continues to be viewed as a cheap source of energy, resulting in numerous investments in new opencast brown coal mines. Such a perception of brown coal energy is only possible if the external costs associated with mining and burning coal are not considered. In

Coal explained - U.S. Energy Information Administration (EIA) The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce. The rank of a coal deposit is determined by the amount of pressure and heat that acted on the plants over time.

In many circles, brown coal continues to be viewed as a cheap source of energy, resulting in numerous investments in new opencast brown coal mines. Such a perception of brown coal energy is only possible if the external costs associated with mining and burning coal are not considered. In past studies, external cost analysis has focused on the external costs of coal burning and associated ...

Pumps are used in mines for dewatering and consume about 18% of the total energy usage in an opencast coal mine. Quantitative estimation of water removal rate in a mine is necessary for designing an effective dewatering system and to minimise energy consumption. In this paper, a generic model is proposed to estimate water and energy requirement for pumping in an opencast mine based on the

Dump trucks are used for transportation in opencast mines and consume about 32% of the total energy use in mines. This paper presents a generic model to benchmark energy consumption for dump trucks in mines. The modelling framework estimates minimum specific fuel consumption (SFC) of dump trucks using mine equipment, engine characteristics and vehicle dynamics.

2019-8-7 Diesel consumption data for the opencast mining activity was estimated by multiplying the coal production data by specific fuel consumption (SFC) by diesel equipments like HEMMs. SFC for the diesel equipments in some of the opencast mines was reported by [18]. Average value of SFC by the diesel equipments was 2.835 liter per tonne of coal ...

2012-5-10 renewable source of energy is wasted. Introduction of surface miner in Indian opencast coal mine solves all the above mentioned problems. Here surface miner cuts coal, size and loads in one single pass which eliminates the need of HEMM for drilling, blasting, excavating and crushing etc. By selective mining of thinner coal seams quality improves.

2020-6-30 primarily aimed at opencast mining, the research should also be applicable to any surface activity associated with any deep coal mine operation. Health Impacts: Reducing coal extraction is required to meet decarbonisation targets and will reduce health risks for communities living near mines, along coal transport services and where coal is burnt.
