प्रश्न
Give geographical reasons:
Mining is developed in Chhota Nagpur plateau of India.
उत्तर
The distribution of minerals is highly uneven in India. The geology of Chhota Nagpur region is very rich in minerals. There is a concentration of minerals like iron ore, manganese, mica, copper, limestone, and lead in the Chhota Nagpur region. The government policy, capital investment in mining activities, technological development, availability of skilled labour, transport facilities, etc., are favourable for the development of mining activity in the Chhota Nagpur region. The development of many mineral-related industries is located in this area, which boosted the development of mining activities.

Primary Economic activity not related directly to latitudinal locations:
Mining is dependent on the extraction of naturally occurring minerals. Explain.
State the two groups of factors that affect the profitability of mining.
Which one of the following is not a method of mining?
Depending on the mode of occurrence and the nature of the ore, mining is of two types: Surface and underground mining. Surface mining is also known as open cast mining is the easiest and the cheapest way of mining minerals that occur close to the surface, overhead costs such as safety precautions and equipment are relatively low in this method. The output is both large and rapid. When the ore lies deep below the surface, an underground mining method (shaft method) has to be used. In this method, vertical shafts have to be sunk, from where underground galleries radiate to reach the minerals. Minerals are extracted and transported to the surface through these passages. It requires specially designed lifts, drills, haulage, vehicles, ventilation system for safe and efficient movement of people and materials. This method is risky. Poisonous gages, fires, floods, and cave-in bad to fatal accidents. The developed economies are retreating from mining, processing, and refining stages of production due to high labour costs, while the developing countries with large labour forces and striving for a higher standard of living are becoming more important. Several countries of Africa and a few of South America and Asia have over fifty percent of the earnings from minerals alone.
