This place is known for opencast coal mining since 1983 under North Eastern Coalfields, a unit of Coal India Limited. In 2018–2019, an international team of researchers discovered fossil impressions of two previously unknown species of bamboo (Bambusiculmus tirapensis and Bambusiculmus makumensis) in the Tirap coalmine. These fossils date back to about 25 million years ago, falling in the late Oligocene period. This discovery strengthened the theory that bamboo came to Asia from India and not from Europe. It also challenged the previous hypothesis that Asian bamboo spread from the Yunnan region of China to India.
