This document provides an overview of longwall mining technology in India and compares it to practices in other countries like China. It finds that while longwall mining was introduced in both India and China around the same time, China was more successful by taking a systematic approach and prioritizing large-scale adoption and indigenous development of equipment. In India, longwall faces experienced many issues like inadequate support capacities, poor matching of equipment, and management problems. Lessons from successful countries and focus on areas like developing local equipment suppliers, identifying more longwall blocks, and improving maintenance are needed to better realize the benefits of longwall mining in India.
