Is the return of activities to rehabilitate the damaged environment either caused by mining or other activities. Rehabilitation is done by re-planting or reforestation of areas damaged by the mining activities.
Some key terms associated with the reclamation, namely:
1. Environment
Unity with all things space, power, and living conditions; including man and his behavior that affect the survival peri-life and welfare of human beings and other living things.
2. Mine Environment
Environmental conditions in the mines which include elements such as: humidity, dust, gases, temperature, noise, water, lighting / lighting.
3. AMDAL (environmental impact assessment)
Abbreviations and environmental impact assessment, namely a study of the impact of planned activities on the environment, and the results used for decision-making process.
4. Environmental pollution
Entrance or the inclusion of living creatures, substances, energy, and other components into the environment and changing the order of the environment by human activities or natural processes, resulting in lower environmental quality to a certain level that causes the environment to be less or not work anymore accordance with the intended.
5. Mine Pollution
Entry of pollutant substances in the form of gas, dust, mud, smoke, energy, biota or chemicals into the environment components (air, water, and soil) as a result of mining and mineral processing so that the environmental quality decreases.
6. Water Pollution
Air containing one or more chemicals at concentrations high enough to harm humans, animals, plants, or material.
7. Environmental Inspection
Surveillance of the environment affected by mining activities and processing, MSL. Evaluating the implementation of EIA, and supervise the implementation of environmental control.
8. Health Inspection
Supervision of the factors that may cause health problems due to the work of environmental pollution, a chemical factor (non-particle and particle), physical factors (noise, vibration, temperature), and biological factors (yeast, worms, and other organisms) .
9. Safety Inspection
Supervision of the factors that may cause accidents due to mechanical motion, MSL. Crushed, buried, knock, fall, and stuck.
10. Mine Safety Inspection
Supervision of inspection in the field that includes the factors that affect safety, occupational health and hygiene company.
11. Mine Inspection, Mining Supervision
Supervision of mining activities which include supervision exploitation, mining, mining procedures, treatment, and supervision of work safety.
The impact of that arise with the existence of mining activities:
1. Positive impact
a. Adding revenue
b. Providing employment
c. Come enhance social development, economic and cultural
d. Allowing the transfer of technology
e. Strengthening environmental safety
2. Negative impact
a. Changing the face of morphology and physiology of the land (land use)
b. Damage the environment, because:
*) Soil fertility loss
*) Land to be bald so easily eroded
*) The flora and fauna disturbed so that the ecological damage
*) Polluting the river
*) Incurred dust (air pollution)
*) The use of mining machinery led to noise pollution / vibration and air pollution
c. Can lead to social and economic disparities
Efforts to control negative impacts:
1. Applying the correct way of mining
2. In the employment needs of local labor as optimal as possible
Environmental Management
1. Handling the problem of dust
2. Post-mining land reclamation
3. Mine water management
4. Waste Management
Challenges ahead
1. Mine production capacity grew, especially with the growing ability of equipment (example: Dump truck 350 tons)
2. Underground mining
3. The issue of industrial safety and environmental
4. Social-economic issues and relations with other sectors
5. Demand for skills and competencies of the higher
