Abstract: In conduct mine transformation and upgrading and underground space deep development, various strategic ideas and technical prospects of contemporary scholars on mine tunnel transformation and upgrading and underground space deep development are deeply discussed. Based on the advanced existing cases in China and abroad, with the support of bionics engineering technology means and assembly building construction technology means, a design concept of using deep underground space of abandoned coal mine roadway to construct a lung convalescence system for COVID19 patients is proposed. The ambient temperature of mine roadway is suitable, and some of the roadways even contain substances beneficial to human bodies. The underground negative pressure air environment has been proved to be very beneficial to pulmonary recuperation. By transforming the main roadway of deep mine with long service life and stable structure into a deep convalescent system, it provides a suitable building environment for pulmonary convalescent.

Key words: abandoned coal mine roadway, mining area transformation, lung recuperation, deep medical treatment
