The DUGL at the CJEM is located in a goaf that is 820 m below sea level and under 1470 m of rock (Fig. 1). The AGL was constructed in an office in an administrative building near the entrance of the CJEM (altitude 590 m). Accessing the DUGL from the entrance of the CJEM requires a 1600 m walk and three elevators, which takes 1.5–2 h. Six environmental parameters [radon gas (1,027, Sunnuclear, USA), O₂ (AR8100, Sigma, China), total γ ray dose rate (AT1121, Atomtex, Belarus) CO₂, air pressure and relative humidity (Testo480,Testo, Germany)] in the DUGL and AGL were monitored at sites 1 m from the incubators, 0.5 m from the ground and 0.3 m from the palisades (DUGL)/wall(AGL). To minimize the effect of natural light on cell growth, the windows of the AGL were covered with black material and the room was illuminated with the same fluorescent lamps as the DUGL 24 h/day. All measurements and the following experiments were conducted under ventilated air.

The air pressure, relative humidity, temperature (testo480, Testo, AG, Germany); total γ radiation dose-rate (AT1123, ATOMTEX, Belarus); and oxygen concentration
(AR8100, SMART SENSOR, China) in the CJEM in the aisles in goafs at 4 depths (with rock covers of 60 m, 300 m, 750 m, 1470 m) below ground were measured on January to April 2018. For each factor, at each recording site in the aisles with a 50 m distance to the shaft, the average of ≥3 measurements was taken. All measurements were conducted under air ventilation.

As reference, the environmental parameters in the aisles of the 12th mine of CPSG were measured from 1 to 6 November 2018. Five environmental parameters (air pressure, relative humidity, temperature, total gamma radiation dose-rate and CO₂ concentration) (Testo 480; Testo, AG, Lenzkirch, Germany) were measured 7 times. The depths of measurements were from 0 to 932 m with a vertical interval from 5 to 243.5 m underground. It is noteworthy that the measurements were conducted under air ventilation.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
