Methane emissions from coal mining are well studied and expected to reach approximately 784 Mt of CO 2-equivalent (CO 2 e) by 2030 1.However, since coal mining itself is being directly targeted in ...
Mountaintop Removal Mining for retrieving minerals from mountain peaks and involves blasting the overburden with explosives above the mineral seam to be mined. The broken mountaintop is then shifted into valleys and fills below. ... The mine is decommissioned by workers or contractors who take apart the mining processing facilities and ...
1. Introduction. Mining activity is mostly represented by these four main operations: drilling, blasting, loading and hauling. For a proper mine planning and design, all of these operations need to be carefully planned in such a manner that can prevent extra loads such as operating costs, environmental footprints, etc. Amongst these operations, …
Optimal blasting. As with all parts of the mining process, the. concept of automation is being readily. discussed in blasting and explosives circles – whether that be using robots to load blastholes or automating the detonation procedure. Unlike other parts of the mining process, however, blasting remains today a largely
Direct reduced iron process with subsequent electric arc furnace process; In contrast to the direct reduced iron process, the blast furnace process can be operated on a large scale. The blast furnace …
As sensors, IoT devices, autonomous drilling systems and remote-controlled equipment become more commonly used in the mining industry, cycle times of the drilling and blasting process can be optimized – in effect reducing downtime, inefficiency and costs. With insights garnered from sensor data, mining professionals can more easily identify ...
A utomation in the mining industry has been burgeoning since the noughties, after the first successful commercial deployment of automated technology in open-pit mine haul trucks in 2007. Since then, it has proliferated to other mining equipment and both open-pit and underground mines. Along with haul trucks, which are arguably …

We know that open-pit mining operations mainly include drilling, blasting, mining, transportation and dumping. Blasting is a very important part of it. Blasting costs account for 15% to 20% of the total cost of open pit mining. Moreover, the quality of blasting directly affects the working efficiency and total cost of the mining process.
Mining is a significant economic activity in India. Even on a small scale, it contributes up to 6% to the total cost of mineral extraction. Pollutants and fugitive emissions from the processes involved in mining are suspended in the air and make it unfit for breathing leading to serious respiratory complications.
