The design scheme of existing refuge chamber only provided an independent living environment without giving emergency hedge downhole emergency personnel to quickly rise well completely out of danger environment. Occurred in the coal mine gas and coal dust explosion and fire accident then rapid spread toxic or harmful gases, and the secondary disasters may occur at any time, At this moment the ground rescue personnel go down to rescue casualties may produce non-essential. To address this issue, Design the drilling of refuge chamber escape mode and Coal PINGSHUO Group Ltd. has been successfully applied. Drilling Escape model not only can provide a basic guarantee for the survival of emergency refuge personnel, but also can sent emergency refuge personnel to the ground through the emergency escape drilling to completely get rid of hedge personnel in hazardous environment.
