Coal mine detect and rescue robot technique research

2009 International Conference on Information and Automation, 2009
Coal mine is a dangerous field, various fatal factors menace people. The rescuers have known the mine tunnel actual situation when a disaster in coal mine occurs. Especially, it is very dangerous to go into the tunnel without detect in advanced because second explosion may occur at any time. Aiming to the task, the rescue robot can be sent to explosion
