Answer: (D) Flooding

Coal mine disasters in West Bengal are mainly due to flooding. The Raniganj and Jharia coalfields are located in areas with high water table and intersecting underground water channels. Flooding from underground water ingress is the primary hazard. The Bord and Pillar method of mining in old workings also makes mines prone to collapse when flooded.
