There is also provided laterally horizontally extending conveyor belt mechanisms and rock fragment-removal mechanism for retrieving rock fragment to the conveyor belt which in turn delivers the same to collection vessels for conveyance to earth surface locations.，下面是Diamond drill and rock fragment excavation device专利的具体信息内容。

权利要求

1. A rock drilling device comprising in combination: a tubular element having inner and outer tubular surfaces and defining a plurality of coolant-flow apertures through the tubular walls of the tubular element with the apertures defining a coolant flow path from within the tubular element to laterally exterior thereof, the apertures extending substantially radially outwardly from the longitudinally axially extending tubular coolant flow path within the tubular element, there being diamond cutting bits arranged along the outer tubular surfaces with the apertures substantially adjacent the diamond cutting bits, and bevel gear means and drive shaft means with the drive shaft means extending along its longitudinal axial axis at an angle laterally relative to the tubular element''s longitudinally axially extending axis and the shaft means being operatively connected through the intermediate bevel gear means for driving rotatably the tubular element around the tubular element''s longitudinally axially extending axis as a result of force transmitted by the drive shaft means to and through the bevel gear means, and the tubular element being supportable by the bevel gear means and the bevel gear means being supportable by the drive shaft means.

2. The rock drilling device of claim 1, in which said diamond cutting bits are arranged substantially helically in a longitudinally axially extending direction along the outer tubular surfaces, and a plug drilling shaft means including a diamond drilling face rotatably revolvable with and fixedly secured to a terminal end of the longitudinally extending drive shaft means with the diamond drilling face extending in a direction substantially transverse to the tubular element''s longitudinally axially extending axis, the diamond drilling face having an area of drilling effectiveness at least as great as a cross-sectional area of the drive shaft means, and a second drive shaft means and a second bevel gear means and a second diamond drilling face each mounted at an opposite end of the tubular element operatively substantially the same as the other drive shaft means, the other bevel gear means and the other diamond drilling face.

3. The rock drilling device of claim 2, and vaporizable coolant and tubular means for channeling the coolant to the tubular element, and in which the tubular means for the coolant extends concentrically within at least one of the drive shaft means and through the bevel gear means operatively to communicate with the tubular element''s coolant flow path.

4. The rock drilling device of claim 3, and power drive means for driving the drive shaft means, and extension support means for supporting the drive shaft means and for extending the same downwardly as drilling proceeds, and encasing means for segregating vaporized coolant from surrounding human being-inhabitable environment and for channeling the vaporized coolant to a location away from the drilling site, and rock fragment-removal means for collecting rock fragments from rock-drilled sites and conveying the same to a rock elimination location away from the drilling site, and substantially horizontally extending Subterranean passage-defining cavern means defining space and horizontal floor structure and conveyor means extending substantially horizontally along the cavern means'' space, the conveyor means being for receiving rock fragments from the rock fragment-removal vessels, and including removal vessel means with removal vessels transportable of rock fragments contained therein from the cavern means to a location at substantially the earth''s surface.
