专利汇可以提供Corpuscular beam in mining and excavation专利检索，专利查询，专利分析的服务。并且There is disclosed a method and apparatus for mining and excavating through rocky terrain without a mechanical tool or machine which must be made rugged enough to withstand the forces and impacts necessary to break rocks. The excavation is carried out with an electron beam which is projected against the rock. The beam is conducted from a generator through a long tube, which may be 20 feet long or more, and is emitted at the end of the tube. The generator and tube may be mounted on the turret of a vehicle so that the tube can swing in an arc of large angle in the plane of a rocky seam or at any angle transverse to this plane. The beam bores an opening in which the vehicle moves which may be in the direction of and/or at an angle to the beam. There is also disclosed excavating apparatus, for example an auger, including a beam generator for breaking up the terrain in which the excavation takes place ahead of the pick-up edge of the auger.，下面是Corpuscular beam in mining and excavation专利的具体信息内容。
1. The method of mining a seam of rock bearing desired material which method comprises projecting on said seam, a corpuscular beam, as distinct from a beam of electromagnetic energy, typically an electron beam, said corpuscular beam being of great length, of the order of 20 feet to 100 feet, and of high energy, typically of above 7,500 watts, said corpuscular beam being produced by a corpuscular beam generator having a long corpuscular-beam gun barrel structure of relatively small cross section, said corpuscular beam operating on said seam to break up said rock and produce a correspondingly relatively narrow slot in said seam, and removing the resulting debris including said material through said slot, said slot being dimensioned of sufficient cross-sectional area throughout its length to accommodate said gun barrel structure and also to permit removal of said debris.
2. The method of claim 1 wherein the corpuscular beam produces X-rays and/or light when it is incident on the seam and the ore-bearing characteristics of the seam are determined from analysis of the X-ray and/or light produced wherever the beam is so incident on the seam.
3. The method of claim 1 wherein the corpuscular beam passes through an aperture near the exit end of the corpuscular-beam gun barrel structure, said beam producing X-rays when undesirably impinging on the walls of said aperture, the said method including the step of maintaining the beam aligned responsive to the said X-rays produced by the impingement of said corpuscular beam.
4. The method of claim 1 wherein the generator is mounted on a vehicle and the vehicle is initially moved in a position opposite the seam with the seam extending on both sides of the vehicle in a direction generally perpendicular to the anticipated direction of movement of the vehicle, the corpuscular beam then scans the rock directly ahead of the vehicle cutting out a passageway great enough to accommodate the vehicle and also scanning and cutting out material from said seam in, and on both sides of, said passageway, the vehicle advancing into the passageway and the corpuscular beam progressively deepening said passageway and penetrating deeper and deeper into said seam ahead of said passageway, the passageway and the penetration into the seam being of sufficient cross-sectional area to permit removal of the debris from the cutting out of said passageway and the material cut out from said seam, and said debris and material being removed as the vehicle advances.
5. The method of claim 1 wherein the corpuscular beam passes through an aperture on the corpuscular-beam gun barrel structure, said beam producing X-rays when undesirably impinging on the walls of said aperture, the said method including the step of maintaining the beam aligned responsive to the said X-rays produced by the impingement of said corpuscular beam.
6. The method of mining a seam of rock bearing desired material, with apparatus including a generator of a corpuscular beam, as distinct from a beam of electromagnetic energy, typically an electron beam, said beam generator being mounted on a vehicle and having corpuscular-beam gun structure, through which the corpuscular beam is emitted, projecting from said vehicle, said corpuscular beam being of high energy typically of about 7,500 watts, the said method comprising moving the vehicle into a position opposite the seam with the gun structure directed on the seam and the seam extending on both sides of the vehicle generally perpendicular to the anticipated direction of movement of the vehicle, causing the corpuscular beam to cut out a passageway in said rock of dimensions great enough to accommodate said vehicle and also to scan said seam in, and on both sides of, said passageway and cut out the material in said seam, causing the vehIcle to advance into said passageway, with the corpuscular beam progressively increasing the depth of said passageway and the depth of penetration of said corpuscular beam into said seam, and removing the cut out debris and material as said passageway is cut out and said seam is scanned, the passageway and the cut out portion of said seam being of sufficient cross-sectional area to permit ready removal of said debris and material.
7. The method of mining a seam of rock bearing desired material, with apparatus including a generator of a corpuscular beam, as distinct from a beam of electromagnetic energy, typically an electron beam, said beam generator being mounted on a vehicle area having corpuscular-beam gun structure, through which the corpuscular beam is emitted, projecting from said vehicle, said corpuscular beam being of high energy typically of about 7,500 watts, the said method comprising moving the vehicle into a position opposite the seam with the gun structure directed on the seam, causing the corpuscular beam to cut out a passageway in said rock of dimensions great enough to accommodate said vehicle and also to scan said seam and cut out the material in said seam causing the vehicle to advance into said passageway, with the corpuscular beam progressively increasing the depth of said passageway and the penetration of said corpuscular beam into said seam, and removing the cut out debris and material as said passageway is cut out and said seam is scanned, the passageway and the cut out portion of said seam being of sufficient cross-sectional area to permit ready removal of said debris and material.
