TLDR
Based on sufficient investigation of existing refuge chamber product overseas,detailed expatiation and analysis were preseated to the oxygen supply,noxious gases removal, air conditioning,environmental monitoring, power supply, attaching supplies and technical indexes in refuge chamber, which provide guidance for analysing the status of refuge chamber technology in the world and the development of Chinese coal mine refuge chamber.Abstract:
In some countries with a well-developed mining industry such as South Africa、Australia,refuge chamber is an important underground emergency rescue equipment,in which trapped miners are protected when waiting for rescue after mine accidents.Based on sufficient investigation of existing refuge chamber product overseas,detailed expatiation and analysis were preseated to the oxygen supply,noxious gases removal,air conditioning,environmental monitoring,power supply,attaching supplies and technical indexes in refuge chamber,which provide guidance for analysing the status of refuge chamber technology in the world and the development of Chinese coal mine refuge chamber.read more

Simulation analysis on structure safety of coal mine mobile refuge chamber under explosion load
TL;DR: In order to check structural strength of coal mine mobiles refuge chamber, a refuge chamber model was established, then a finite element method was instituted for it to ensure the refuge chamber would not be severely damaged when gas or coal dust explosion suddenly happened as discussed by the authors.

Statistical analysis of major tunnel construction accidents in China from 2010 to 2020
TL;DR: Wang et al. as discussed by the authors conducted a statistical analysis on 48 cases of major tunnel construction accidents (MTCA), defined as an accident that results in more than three deaths in China from 2010 to 2020, and examined the accident characteristics, including classification, time, region, location, construction method, and risk source.
