Nov 05, 2020 Opencast nickel mining is common in natural forests of Indonesia. However, rehabilitation of postmining degraded land is difficult. We investigated the effect of opencast nickel mining on soil chemical properties and the growth of two fast-growing tropical tree species, Falcataria moluccana and Albizia saman . Soil was collected from post-nickel mining land and a nearby natural …
The Parsa mine – open cast mining involves digging for coal after removing all the vegetation and soil from the area -- came up for consideration of the environment ministry’s expert appraisal ...
Coal mining is one of the significant end-use industries in the surface mining equipment category Asia and Africa are going to be the fastest-growing regional markets for SE during 2017–2019 Demand from large developing countries, such as India, China, and Indonesia, could increase the size of the market
OBJECTIVES To answer the question whether living near opencast coal mining sites affects acute and chronic respiratory health. METHODS All 4860 children aged 1–11 from five socioeconomically matched pairs of communities close to active opencast sites and control sites away from them were selected. Exposure was assessed by concentrations of particulate matter with aerodynamic diameter 10 μm ...
Apr 04, 2019 Coal mining methods. In contrast to most global production, the majority of black coal mined in Australia is produced from open-cut (open cast) mines. This ratio of 3:1 open-cut/surface to underground mines also applies to the broader (i.e. non-coal) local mining sector.
Sep 26, 2020 Rio Tinto. Rio Tinto, one of the largest mining companies in the world, started out in 1873 as a copper operation in Spain but now has operations on six continents, with the largest presences in Australia and North America. Its products include aluminum, copper, diamonds, coal, uranium, gold, iron ore, and industrial minerals (borates, titanium ...
Oct 01, 2017 As the world’s top coal exporter, Indonesia has witnessed the effects of massive coal expansion: following deregulation of the coal sector in 1983 to attract foreign investment, transnational mining companies geared production towards export rather than domestic consumption due to the higher profit margins available, and propelled by demand ...
May 01, 2021 Several studies have demonstrated that the hydrological impact of coal mining is proportional to the upstream areal extent of mining (e.g., Petty et al., 2010, Bernhardt and Palmer, 2011, Lindberg et al., 2011). An implication of this is that the presence of multiple mines in a catchment is likely to have a more substantial impact on the ...

Dec 23, 2020 Being realistic about coal mine rehabilitation in Indonesia: An ecological perspective. Analysis by David Woodbury and Arbainsyah on 23 December 2020. Once covered in vast tropical forests, East ...
Open-cast mining increases the division between a relatively small work-force and a local impoverished proletariat. The open-cast drive explains the rapid increase of total CIL coal production from 200 Mt in 1992 to 430 Mt in 2010. In the following we have a brief look at the ‘controlled default’ of …

“Welcome to the tenth edition of PwC Indonesia’s Mining in Indonesia: Investment and Taxation Guide. Since the Law on Mineral and Coal Mining No. 4 of 2009 (the “Mining Law”) was promulgated, various implementing regulations, including a number of amendments, have been issued by the Government in pursuing the goals of the Mining Law.
Investments in export-oriented coal mining projects are under consideration in a number of countries. They are at various stages in the development process and here are classified as “more-advanced” and “less-advanced”1. More-advanced projects under development represent about 93 Mtpa of coal mining capacity, of which about 69% are for metallurgical (met) coal though it is less than 20 ...
May 27, 2020 Mining remains an essential and growing part of the modern industry. By some estimates, it makes up nearly 45% of the total global economy, and mineral production continues to increase as demand for raw materials grows around the world.. However, many mining techniques still in use can have serious impacts on both the mining site itself and the surrounding environment.
Nov 21, 2020 Mining of coal around the world is being continued to meet the ever-growing energy demand. Mining involves extensive clearing of ground cover, change in physiography, generation of massive solid and liquid wastes to reach coal and thereby alters ecology and environment of the mining site as well as the neighboring areas. Depending on the nature, origin and seam arrangement of a coal …
Mar 20, 2021 Ajit Patowary. The report of the Ministry of Environment, Forest and Climate Change (MoEFCC) fact finding team (FFT) submitted on February 18, 2021, on the Tikok open cast coal mining project of the Coal India Ltd (CIL) throws new light on the issue of diverting a 98.58-hectare area of the Saleki proposed reserved forest for coal mining.
Jun 05, 2020 Dehing Patkai: Chronological mapping of coal mines reveal degradation. Much has been spoken about the issue of coal mining in Dehing Patkai. The debate over whether it is an elephant reserve or a reserve forest or a wildlife sanctuary has taken people through a mental maze which only opens up more questions than it answers.
The findings from the interviews confirm that regional variation in follow-up implementation is a result of social, environmental, economical and political factors. To further explore these factors, three case studies of open cast coal mining were conducted.
Apr 04, 2019 Coal mining methods. In contrast to most global production, the majority of black coal mined in Australia is produced from open-cut (open cast) mines. This ratio of 3:1 open-cut/surface to underground mines also applies to the broader (i.e. non-coal) local mining sector.
Jul 27, 2012 Examples of environmental degradation caused by Freeport mine operations in Indonesia is presented by Chatterjee, P., Human Rights-Indonesia - US mining giant implicated in Indonesia atrocities, 1995; Press, E., Freeport: Corporate Predator, The Nation.
The Indonesian coal industry is rather fragmented with only a few big producers and many small players that own coal mines and coal mine concessions (mainly in Sumatra and Kalimantan). Since the early 1990s, when the coal mining sector was reopened for foreign investment, Indonesia witnessed a robust increase in coal production, coal exports ...
Dec 17, 2015 Indonesian Coal Mining Boom Is Leaving Trail of Destruction. Since 2000, Indonesian coal production has increased five-fold to meet growing domestic demand for electricity and feed export markets in Asia. The intensive mining is leading to the clearing of rainforest and the pollution of rivers and rice paddies. By Mike Ives • December 17, 2015.

Underground mining impacts directly on the health of those working underground. Opencast mining activities result in serious air qual-ity deterioration due to dust and gaseous pollutants in and around the mining areas (Ghose & Majee 2001). Coal gangues (mine tailings) are industrial residues that are discharged when coal is excavated
Dec 28, 2018 Impact assessment of coal mining of Gare IV/6 Coal Block (GCB) on river water (Kelo River) and groundwater and the interaction between them were studied through hydrological studies like water-level monitoring, short and long-term river flow measurements, isotopic characteristics, and groundwater flow modeling. The hydrological study reveals that the groundwater flow is towards the …
