| Abstract: | Through the analysis of the fracture reason and of the stress state of the danger point of the shaft wall,the measure used to prevent the fracture of shaft that does not break earth yet is advanced in order to eliminate the factor that results in shaft fracture.The measure used to prevent the fracture of shaft that does not break is put forward in order to prevent the fracture of shaft.The measure of used to control the fracture of shaft wall is given in order to resume the use of shaft. |
