Research on the protection system of refuge haven of underground mine
GAO Na1,JIN Long-zhe1,FAN Jing-guang1,2,ZHAO Yan1,HUANG Zhi-ling1,ZHANG Xiao-chen1(1.School of Civil and Environmental Engineering,University of Science and Technology Beijing,Beijing 100083)(2.China Chemical Safety Association,Beijing 100713)
The research determines that the whole protection system is composed by fireproof anti-explosion airtight system,oxygen supplying system,desiccant cooling system,monitoring and supervision system,power system,communication system,position system,lighting system,medical system,food,water,health system,according to the protection functions of refuge haven.The anti-explosion influence factors of fireproof anti-explosion airtight system are reflected pressure,incident pressure,static loading,materials and safety factor according to the theoretical analysis.The minimum air quantity of air supplying system is 36 m3/min of the refuge haven which can accommodate 100 people and the minimum oxygen quantity of other air supplying modes is 60 L/ min according to calculation.The research supplies scientific basis and authentic data for the study of refuge haven protection system,establishes the foundation for the study of emergency rescue system.
