The Directorate of Geology & Mining said the coal mine accident that killed six labourers and caused injuries to four others on January 25 in Ruchan village, under the Bhandari sub-division of Wokha district, Nagaland, was caused by the fire and explosion of methane gas.

In a releases, the department said the fire and explosion might have occurred due to a frictional spark while using a portable handheld drilling machine.
