‘Self-heating water behind gas leak in Shinas mine’

MUSCAT: A gas leak at a mine in the Wilayat of Shinas was caused by an increase in temperature and the self-heating of water inside the mine, according to the director of the Earth Sciences Research Centre at Sultan Qaboos University.

“There is a need to examine the rising gases and water vapour for the possibility of containing sulfur gases,” said the director of the Earth Sciences Research Centre at Sultan Qaboos University.

The Ministry of Environment and Climate Affairs (MECA) has taken samples from the location as part of an investigation, and the results have not yet been announced.

In a statement the Ministry said, “The ministry has sent a specialised team, with the aid of the Public Authority for Civil Defence and Ambulance and the Public Authority for Mining, as well as a representative from the Shura Council, in cooperation with a consultancy, with the goal of discovering the nature of the gas and collecting samples.”

Professor Subhi Jaber Nasr, the Director of the Earth Sciences Research Centre, provided a scientific explanation of this phenomenon, noting, “There are a group of factors contributing to self-heating, temperature increases and the formation of hot spots in mine areas. Thus, heating the water in the mine’s surface and the cracks in its depths become steam that rises into the atmosphere with the effect of increased steam pressure.”

“These factors cause atmospheric humidity, increases in air temperature and oxygen uptakes, increased particle sizes, greater amounts of metal sulfides, greater ambient temperatures, and rising pH,” Professor Subhi said.
