摘要： This tunnel excavation method includes a step of excavating three first tunnels that are substantially parallel to each other in a first excavation step. Second tunnels are excavated that intersect the first tunnels in a second excavation step. A boring machine is used that performs excavation in a state in which a gripper pushes against the side wall of the tunnel.

摘要： A highwall mining equipment extraction and retrieval apparatus and method is disclosed. It includes remotely operable hydraulic cylinders fixed to the mining head and stabilizing arms which brace the mining platform against the face of a mine. Wire ropes extend from hydraulic cylinders, through channels in the pushbeams, through lockable blocks fixed to the mining platform, and onto storage spools. The hydraulic cylinders operate from an extended to a retracted position. When a mine collapse occurs, an operator can remotely actuate the lockable blocks and the hydraulic cylinders, thereby locking the wire rope to the platform and pulling the mining head and pushbeams towards the platform. If the obstruction remains, the locking blocks can be unlocked, the hydraulic cylinders extended from the retracted position, the excess wire rope pulled from the mine, and the process can then be repeated until the equipment is free from the obstruction.

摘要： A method and apparatus is provided for determining structural change in a mining operation. A first scan of gateroad surfaces is obtained and information of the scan profile is stored. At a later time a second scan of the gateroad surfaces is then obtained. Information of the scans can be registered and any difference noted. If the difference exceeds a threshold a warning can be provided indicating a gateroad structural change that may be hazardous. The scans can be made from a single sensor, or from multiple sensors (301, 303). In the case where the sensors (301, 303) are mounted on a gateroad traversing structure (109), the distance of spacing of the sensors (301, 303) can be used to determine when the sensor (303) has reached a position of movement or travel of the gateroad traversing structure (109) where the scan from sensor (301) was made. A distance sensor (309) can be provided to determine the distance of movement and where the scans coincide.

摘要： The noise spectrum in a mining chamber is captured by at least one microphone and is digitized and filtered to separate an operation-typical pattern from an operation atypical pattern. The operation atypical pattern is compared with reference patterns to establish the malfunction or vocal command or emergency and the apparatus is automatically operated in response thereto.

摘要： There is disclosed a mobile sludge handling apparatus which comprises first, second and third vehicles (2, 3, 4) which are coupled together to form a composite mobile unit. The first vehicle (2) carries a sludge-pump unit (5), and the second vehicle (3) carries a filter unit (6) which is arranged to receive sludge pumped thereto from the first vehicle (2) and to separate-out solid material from the sludge. The third vehicle (4) carries a conveyor unit (7) which is arranged to receive separated-out solid material from the second vehicle (3) and to convey such material to a discharge point for the apparatus. The apparatus is particularly suitable for use as an underground device for draining mining sludge, in which sludges or slurries of liquid and solid material underground can be processed on the first and second vehicles (2, 3), and only the solid residue is conveyed by the conveyor unit (7) on the third vehicle (4) to be collected in tubs (38) which are then transported to the surface for subsequent discharge of the solid material.

摘要： Coal is reduced to ash in place by gasification using in situ production techniques, resulting in significant void space underground, which in turn causes roof fall and subsidence. Overburden collapse is stabilized by backfilling with foaming mud cement that hardens into an expanded solid, which quenches and fills the production module and seals residual ash. Rubble volumes and subsidence cracks are sealed against water incursions and contaminated water excursions. Surface facilities above barrier pillars are protected from destructive forces of subsidence draw.

摘要： A travelling mining appliance, particularly a travelling drilling and/or bolting appliance, having a protective roof. The appliance comprises a driving station used for controlling the movement of the appliance on the ground and a separate operating station, located on the side of the appliance, for controlling the drilling and/or bolting device. According to the invention, the roof is mounted to pivot on the appliance about a vertical axis. It is thus able to move in an angular manner between a first position in which it is located above and protects the driving station, without projecting beyond the width of the appliance and a second position in which projects beyond the side of the appliance and is located above the operating station thus protecting the operator who is standing opposite this station.

摘要： Apparatus for the in-situ retorting of carbonaceous deposits includes a plurality of retorts connected to a common exhaust tunnel effectively free of broken shale into which products of the retorting are discharged. To allow simultaneous mining, rubblization and retorting of the in-situ retorts, the exhaust tunnel is provided with doorways between the retorts. Doors movable in the exhaust tunnel are adapted to seal against the doorways to prevent flow from retorts in which retorting is in progress to retorts under construction. A trench in the exhaust tunnel is provided for flow of liquid products produced in the retorting. A liquid seal under the doorways communicates with the trench to provide a passage for liquid flow past the doorways and to prevent upstream flow of gaseous products through the passage for the liquid flow.

摘要： In the sampling of a rock surface, dust that is formed by action of a compressed air driven rock cutting wheel is entrained in an air stream that is drawn into a shroud that surrounds all but a minor part of the cutting edge of the wheel and thence to a cyclone where it separates into a sample collector. High velocity exhaust air from the wheel-driving mechanism passes through an air ejector to provide a vacuum that causes the air stream to flow through the sample collecting system.
