2016
As regard to the problems exposed in the construction of emergency refuge system, including the poor reliability of hedging facilities, the contradiction between hedge and escape, time consuming, high cost and big risk of drilling rescue technology, etc., shaft drilling escape and rescue system is brought up, which is a combination of emergency refuge technology and drilling rescue technology. Through doing researches on man-loading experiment and live sheep lifting experiment, key parameters of drilling escape and rescue system are tested, like no-supply guarantee time, response time, human survival environment and so on. This paper also studies comfort and physiological parameters of experimenters and the influence drilling has over refuge chamber air supply system.
