text: An excavating and mining machine comprising a tubular casing formed with a coaxial housing closing one end thereof mounted for translation parallel to and for rotation about its horizontally-disposed axis, an independently power-actuated excavating head generative of a bore accommodating said casing and its mounting fixed diametrically across, extending coaxially from and rotatable with the end of said housing remote from the casing, power means in rotational driving relation with said casing, separate power means in said housing in 9 driving relation with actuable elements of said head, a spiral scoop between and rotatable with said casing and housing adapted to infeed excavated material to the casing interior as an incident of its rotation, a spiral flight fixed interiorly of and rotatable with said casing adapted to translate material infed by said scoop longitudinally of the casing to delivery through the end of the latter remote from said housing as an incident of casing rotation, abutments selectively clampable to the walls of a bore generated by said head spacedly embracing the translatable assembly, and power means pivotally connecting between and operatively intercoupling each of said abutments with the translatable assembly selectively actuable to shift the latter axially relative to the associated abutment.
