Must non-combustible materials be used in the construction of ground gas extraction pump house?

I have to. According to the "Coal Mine Safety Regulations", the ground pump room must be built of incombustible materials, with a fire resistance rating of Grade II and a lightning protection device. Not less than 50m away from the entrance wellhead and main buildings, and protected by fences or fences. Therefore, the ground gas extraction pump house must be built of incombustible materials.
