In the field of environmental restoration, the method of bioremediation is highly adaptable, eco-friendly and rapidly growing. It converts the complex contaminants of an environment into less toxic or harmless forms. The most acceptable and successful implication of bioremediation starts with the initial stage of site characterization.

According to the production scheduling solutions, the NPVs of the proposed GA and SimSched DBS are 3459 M$ and 3351 M$, respectively. At the end of the mine life, the total NPV generated from the elected solution (close to the mean value) of the proposed GA is 108 M$ greater than the NPV achieved by the SimShed DBS, which …

The safety of miners is the primary concern in the underground coal mine. As mentioned earlier, major mine accidents occurred accompanying the explosion of CH 4 and coal dust, which took many miners' lives and hampered coal production (Tutak and Brodny, 2019; https://coal.nic.in (Anon, 2021a)). In recent years many researchers have …

The digital mine acts as a simulation and is a tool in the evaluation of mineral resources, the general planning of mining constructions, exploration design, mining engineering, production safety, geological disaster forecast, and management decisions (Wu and Xu 2013, 2014). A digital mine information system may be used to prepare …

Some examples of natural environmental hazards are bacteria, viruses, and poisonous plants. Physical environmental hazards include radiation, lifting heavy objects, and natural disasters. A couple ...

Mine abandonment, decommissioning, and repurposing can also result in significant environmental impacts, especially soil and water contamination.

Although mining has been an essential economic activity for centuries, it comes with significant environmental impacts. The mining industry's operations …

3. Air Pollution. Air pollution is an environmental problem that causes soil pollution, water pollution, and respiratory illnesses in humans, animals, and birds. Air pollution is what we call the suspended particulates that become part of the atmospheric gases that we breathe.

5. Self-reliant operation of a solution and easy configuration. Further speaking to the point that Mine Production processes are dynamic, providing solutions to execute these processes must also by dynamic and flexible. Control Room and Technical Services SMEs need to feel like they are in charge and not hindered by rigid controls or …

The environmental challenges from coal mining include coal mine accidents, land subsidence, damage to the water environment, mining waste disposal and air pollution. These are either environmental pollution or landscape change. A conceptual framework for solving mine environmental issues is proposed. Clean processes, or remediation …

The open pit mine production scheduling problem determines a sequence of three-dimensional, notional block extraction that maximises net present value (NPV) of future cash flows and satisfies technical and operational constraints such as precedence between blocks and resource availability.

Water scarcity and complex water inrush hazards present formidable obstacles to the advancement and application of coal resources in the Ordos Basin of the Yellow River Basin, where extensive and widely distributed Jurassic coal strata are found [4].The per capita water availability in the region is only 1318 m 3, with water resources …

Li et al. (2009) proposed a coal mine safety assessment index system including geological exploration, worker operation, safety hazard monitoring and management, production technology, machinery and equipment, and safety management. There are relatively many risk factors for coal mine gas disasters, and the classification …

Mine wastes, which include tailings and lowgrade waste rocks that were accumulated during the mine operation in these legacy mines, contain elevated potentially toxic elements (PTEs) values (e.g ...
