摘要： There is provided a method and apparatus for upwardly excavating a shaft through destructible underground rock. The cutting operation is carried out by full face boring without relying on blasting. An operation for supporting the shaft side wall is carried out by means of frame segments loosely following the advance of the bit. The cutting operation and supporting operation are independent from one another. The diameter of the bit is contracted after the cutting operation to allow the bit to be lowered down through the frame segments.

摘要： There is provided a method and apparatus for supporting the wall of an upwardly excavated shaft. Cylindrical support frames which are successively thrust up through the shaft are respectively composed of several arcuate members and one or more disjointing members. A plurality of top supporting plates are provided on the top of the series of the cylindrical frames and are designed to fall inwardly toward the center of the shaft after the excavation of the shaft is terminated, thus constructing an umbrella like device for supporting the roof of the shaft.
