专利汇可以提供Mine lining and conveyor combination专利检索，专利查询，专利分析的服务。并且The roof of an underground excavation is supported by a lining, and a conveyor extending along the mine face is reinforced at least in a section facing away from the mine face and supporting at least one cantilever beam and a hydraulic advancement assembly. A floor base of the lining is provided with recesses for guidingly accommodating the cantilever beam in the floor base, so as to permit relative movement of the conveyor and the lining in the direction perpendicular to the mine face, the lining and the conveyor alternately serving as retaining means for each other during the step-wise advancement of the combination.，下面是Mine lining and conveyor combination专利的具体信息内容。

权利要求

1. In an excavating arrangement, a combination comprising a roof support having a floor-engaging base, a shield pivoted to said base and extending over the same toward the excavation face, a roof-engaging cap pivoted to said shield and extending beyond the same toward the excavation face, and a pit prop extending between said base and said shield; conveyor means extending along the excavation face underneath said cap and also engaging the excavation floor; means for displacing said roof support and said conveyor means relative to one another and sequentially toward the excavation face; and means connecting said roof support with said conveyor means and limiting said displacement of said roof support and of said conveyor means relatively to each other to linear displacement only in direction towards the excavation face while preventing any other relative displacement of said roof support and conveyor means, so that said conveyor means acts as an extension of said floor-engaging base of said roof support and reduces the tendency of the latter to tilt toward the excavation face about said floor-engaging base.

2. A combination according to claim 1, and further comprising means for removing the material from the region of said conveyor means, said removing means being supported on the latter.

3. A combination according to claim 1, wherein said connecting means includes at least one beam rigidly coNnected to said conveyor means and extending therefrom toward said roof support.

4. A combination according to claim 3, wherein said displacing means includes a cylinder-and-piston assembly extending between and engaging said conveyor means and roof support.

5. A combination according to claim 4, comprising an additional beam spaced from the first-mentioned beam, said base comprising two base beams with provided with a channel for positive guidance of one of said beams, and transverse beam means for interconnecting said two base beams, and wherein said cylinder and piston assembly is rigidly connected to said transverse beam means intermediate said two base beams.

6. A lining according to claim 4, wherein said beam is longer than said floor base by at least the length of a stroke of said cylinder and piston assembly.

7. A combination according claim 4, wherein said beam comprises a box section adapted for accommodation of said cylinder-and-piston assembly; and wherein said base comprises two base beams parallel to said beam, and two pairs of transverse beams normal to said base beams and interconnecting the same, said connecting means including female guiding means mounted on said transverse beams for positively guiding said beam therein.

8. A combination according to claim 3, and comprising means for reinforcing said conveyor means at least along a section thereof and wherein said beam is rigidly but detachably connected to said conveyor means in said reinforced section of the same.
