SUN Ji-ping(State Key Laboratory of Coal Resources and Safe Mining,China University of Mining and Technology(Beijing),Beijing 100083,China)  
The construction principles of the refuge chamber and rescue capsule underground the coal mine were presented.It includes no excessive output and excessive capacity power supply,no issues in safety,no influence with mine ventilation and safety production,responding the emergency quickly,maintenance-free or easily do it,economical and practical,etc.The survival section and device section in rescue capsule should not be separated,and the rescue capsule should not be built in tunnel.Several small or medium size refuge chambers and rescue capsules should be distributed within the specific region.The refuge chamber and rescue capsule should adopt high pressure gas expansion refrigeration;the air blower should adopt air power fan;it should use water of condensation to remove damp at the heat exchanger's surface of refrigeration system;it should use compressed oxygen to supply oxygen;it should not adopt storage battery or external power to supply illumination system.It should equip with the portable detectors which detect O2,CO,CO2,CH4,temperature,humidity;the sensor and its substation,staff location monitoring substation and dispatcher telephone should use matching equipment of existing system;the air vent holes of rescue capsule and the pipelines connecting with compressed air self rescue,supply water rescue,safety monitoring,staff location monitoring and communication system should be placed on both sides of lane.The soft rescue capsule should not be applied to the coal mine;lanes and workplaces should have no less than 2 safety walk paths to surface safely,excepting heading faces and temporary workplaces.
