CHANGSHA - A manufacturer in Central China's Hunan province announced that its safety shelter can sustain 10 people for 111 hours during mine accidents.

China's top safety administration has called on all mines to finish construction of emergency relief systems by 2015 in a directive that is driving more than 100 companies in the country to develop the chambers for a market potentially worth 400 billion yuan ($63.3 billion), according to insiders.

"It is a place that I can move into and sleep and eat well inside," said Wang Ying, coming out of the closed compartment on Sunday after 111 hours with other nine people.

"From biscuits and water to magazines and cards, all the necessities normally found on a train can be found there," Wang said, referring to how he passed the "boring" days.

Resembling a train carriage, the box chamber went through tests in which electricity and air supply were cut off from it, and surrounding temperature was constantly kept at 55 C.

Wang Shengchu, deputy general manager of the manufacturer, said the steel shell of the mobile capsule can withstand pressure as high as 60 kilograms per square centimeter.

And easily accessible meters in the insulated compartment give a reading of the temperature as well as the concentration of gas and toxins outside.
