Design and Development of a Scaled-Down Fully Automated Indigenous LHD Machine
As of the latest available data, underground mining contributes approximately 4% of India's total coal production, with the remaining 96% derived from opencast mining methods.imma.org.in This is notably lower compared to other major coal-producing countries; for instance, China obtains over 90% of its coal from underground mines, while the United States and South Africa produce about 37% and 50% from underground operations, respectively.The Financial Express
The expansion of underground mining in India holds significant potential, particularly as surface reserves become depleted and the need to access deeper coal deposits grows. Advancements in mining technologies, such as mechanized powered supports and longwall mining methods, are expected to improve the viability and safety of underground operations. These developments could lead to increased coal production, reduced environmental impact, and better compliance with land-use regulations, thereby supporting India's energy security and economic growth.
India possesses substantial coal reserves, with estimates indicating around 378.21 billion tonnes as of April 1, 2023. Coal India However, a significant portion of these reserves remains unexplored due to challenges such as deep deposits, complex geology, and safety concerns. Advancements in automated Load-Haul-Dump (LHD) technology can play a pivotal role in accessing these otherwise inaccessible reserves.
