Capsule asylum cavern is in the process of the miners themselves, to provide a refuge. Asylum cavern is divided into temporary and permanent asylum cavern asylum cavern. So again! What's the difference between them.
Refers to the temporary asylum cavern set on mining area or mining area disaster avoidance route, researchers focused work no more than 500 meters, which has the function of emergency actions underground roadway heading for special purpose, mainly in the service of mining working face and its nearby area, length of service is generally not more than 5 years. The permanent asylum cavern shall ensure that during the period of service is not affected by mining. Temporary asylum cavern transition room should be not less than 2.0 m squared; Living room of the clear height of not less than 1.85 meters, each person should be not less than 0.9 meters 2 area of effective use, number of design safety rating of not less than 10 people, not more than 40 people.
Which has the function of emergency actions permanent asylum cavern underground roadway heading, dedicated service in the whole mine, horizontal or mining area, mainly in the bottom, horizontal alleys, mining area (panel) route to avoid disaster, the service life of not less than five years. Permanent asylum cavern transition room net area should not be less than 3.0 m squared; Living room of the clear height of not less than 2.0 meters, each person should be not less than 1.0 meters 2 area of effective use, number of design safety rating not less than 20 people, should be not more than 100 people.
Capsule safety management:
Capsule safety system management system, appoint specialized agencies and personnel for capsule safety system maintenance and management, guarantee the normal using of the state. Instructions on the use of the capsule should be concise, readable, guide the safe-haven miners used correctly.
Should every three months to equipped with a cylinder 1 allowance checks and system commissioning, the pressure in the cylinder is less than 8 million mpa, should be timely fill gas.
Maintenance and inspection should be conducted on a regular basis and supporting equipment, and replace product manuals on schedule needs regular replacement parts and equipment.
Safety facilities for 1 time every year systemic functional testing, including oxygen, power supply, air tightness and harmful gas processing, etc.
Should guarantee the storage of food, water, medicine and other always is in the warranty period, the outer packing should be clearly labeled expiration date and replacement time next time.
Should every 10 days of equipment power supply (including backup power) inspection and test for 1 time.
Enterprise technical documents shall establish emergency safety facilities, accurate records of emergency safety facilities installation, use, maintenance, accessories with product replacement and other relevant information.
After inspection found that the safety facilities can't normal use, should be timely maintenance process. Mining area of the safety facilities can't normal use, should stop mining operations.
