【正文】 ng districts and 2 worked faces. Time of constructing shaft is months. This worked fece is middle 1 and right 1 worked face, ords 330 days every year. Adapt “ threeeight” work situation, work face is 200 meters length of circle is , and times is 8 one day. Because my limit working ability and time. There must be lots of faults in this design. I plead with dirextors point them out and redify it, and I will accept it sincerely and humblely.
