Draft:1994 Malangas mine explosions

In 1994, two explosions occurred in a coal mine owned by the state-run Philippine National Oil Company in Malangas, then part of Zamboanga del Sur, in the Philippines. The first explosion in a tunnel in March 1994 killed eleven.

The second took place on the evening of August 29, in the same tunnel. Municipal mayor Cecilio Tura said that the mine collapsed, making rescuers having difficulty to enter the tunnel. Provincial governor Isidoro Real Jr. reported that at least nine workers who had suffered burns were brought to Cebu City. Bodies were later found inside a flooded mine. By September 3, the death toll was 81, at least a worker was missing. It is the country's worst mining disaster.

PNOC Energy Corporation president Nazario Vasquez said that at that time of the accident, about 170 miners were working about 150 yards below the ground. The cause of explosion is unknown, although there were conflicting reports. According to an official, a pocket of methane gas was hit by miners. Mayor Tura said that it was triggered by dynamites.

Prior to the disasters, the country's largest underground coal mine produces 200,000 tons of coal annually.

In 2018, a memorial site, which includes a memorial cross and a marker, was erected in the Shaft 3 Area in Barangay Ladicha in line with the commemoration of the accident.
