| Abstract: | A fornltila for calculating the heading section of arbitrary three-centered arch and circular arch types was derived in this paper. The formula presented in Tom 3 of《Mining Design Manual》is for approximate calculation,the area value determined from which is some less than that obtained from the formula given here. |
