Abstract
A mining machine for performing a continuous mining operation in hard rock. The operating portions of the machine are mounted on substantial deck sections hingedly connected to each other to promote maneuverability of the machine in confined spaces. A mining implement capable of breaking ore from the solid is mounted on a rotatable, extensible boom and broken ore is collected by power operated means also provided on the machine. The machine may be adapted for remote operation through a remote hydraulic and/or electric control and may be provided with optional wheels or alternatively may be self propelled.
Claims11
A mining machine for underground mining in relatively hard rock formations, comprising a first section supporting a mining implement capable of breaking ore from the solid, said first section having a first deck supported on first side beam members on each side of the machine and having ground engaging skid surfaces, and a second section supporting a source of power for said mining implement, said second section having a second deck supported on second side beam members on each side of the machine and having ground engaging skid surfaces, said first and second side beam members on the respective same side of the machine being substantially alignable with each other and said first and second sections being detachably joined to each other by a pivot mounted near each side of said machine, support means associated with said first deck for supporting the mining implement on said first deck and means for moving along the ground at least one of said first and second sections.
A mining machine for underground mining in relatively hard rock formations, comprising a first section supporting a mining implement capable of breaking ore from the solid, said first section comprising first side beam members on each side of the machine having ground engaging skid surfaces and a first deck attached to said first side members so as to form a first closed channel underneath said first deck, and a second deck section hingedly connected to said first section and supporting a source of power for said mining implement, said second section comprising second side beam members on each side of the machine having ground engaging skid surfaces and a second deck attached to said second side members so as to form a second closed channel underneath said second deck, said first and second channels being longitudinally alignable, and means for moving said broken ore through said channels underneath said machine.
