How many of the statements given above are correct?
(a) Only one
(b) Only two
(c) All three
(d) None
Answer: (C)
Explanation: With large metal pieces hindering machine drilling in Uttarakhand tunnel rescue operation, now it has been planned to use Rat-Hole Mining method to drill the remaining few meters. Rat-hole mining is a method of extracting coal from narrow, horizontal coal beds which is prevalent in Meghalaya. The term “rat hole” refers to the narrow pits dug into the ground, typically just large enough for one person to descend and extract coal. Once the pits are dug, miners descend using ropes or bamboo ladders to reach the coal seams. The coal is then manually extracted using primitive tools such as pickaxes, shovels, and baskets. Once the coal seam is found, rat-hole-sized tunnels are dug horizontally through which workers can extract the coal. Rat hole mining poses significant safety and environmental hazards. The mines are typically unregulated, lacking safety measures such as proper ventilation, structural support, or safety gear for the workers. The mining process can cause land degradation, deforestation, and water pollution. They often persist due to economic factors and the absence of viable alternative livelihoods for the local population. The National Green Tribunal (NGT) banned the practice of rat-hole mining in 2014, and retained the ban in 2015. Hence, all statements are correct.
