  • Patent number: 10280749
    Abstract: A method for deformation control of large-span tunnel in chlorite schist stratum. The method divides the large deformation of large-span tunnel in chlorite schist stratum into five deformation grades according to the surrounding rock conditions of the tunnel. In response to each deformation grade, the deformation control of large-span tunnel is determined so as to ensure the safety and stability of the tunnel support structure and to avoid the clearance intrusion caused by tunnel deformation.

    Abstract: A tunnel excavation technique using a water jet. A water jet system includes a moving unit movable back and forth with respect to an area to be blasted for tunnel excavation, an articulated robot arm mounted on the moving unit, a water jet nozzle which ejects high-pressure water and an abrasive toward an area to be excavated, and a control unit which controls the moving unit, the articulated robot arm and the water jet nozzle. A free face having a predetermined depth is formed of the area to be excavated in the direction in which the tunnel is to be excavated using the water jet system. Since the blasting is performed after the free face is formed, blast vibration can be effectively restricted.

The light source in the form of a laser on the mining machine, directed toward the roof support. The roof support guide is on the roof support above the mining machine, so that when the alignment between the mining machine and the roof support is as desired, light from the light source falls in a predetermined location relative to the roof support guide. When the mining machine is not in proper alignment with the roof support, the light source does not fall within the predetermined location relative to the roof support guide.

  • Patent number: 6942301
    Abstract: A method and device for drilling and setting adhesive anchor bolts close to the mine face during the cutting operation of a tunneling or mining machine which is capable of being displaced on a traveling mechanism and includes a cutting cylinder or cutting head rotationally mounted on a cantilever arm pivotable in a vertical direction, and optionally in a horizontal direction. The method is carried out in a manner where the substantially horizontal forward movement of the cantilever arm at break-in cutting is detected and a signal is generated during break-in cutting to block commencement of a working cycle for drilling and anchoring. A controller (16) for excavation of material on the mine face is networked with a controller (15) for actuation of the anchor drilling and setting device (10) via radio, electrical or optical lines (17).

  • Publication number: 20040245843
    Abstract: A mining system for advancing and retrieving a mining vehicle such as a miner, material transfer units or, shields into and out of mines. The system includes a platform from which the vehicle is advanced into a mine by means of a pusher. Subsequent vehicles are placed onto the platform, connected to the preceding vehicle and then advanced into the mine. If desired, shields and a miner or material transfer unit may be simultaneously advanced into the mine in the same manner. To retrieve the vehicle, the pusher is reversed and pulls each vehicle from the mine in reverse order. If desired, the shields may remain in the mine and the miner and transfer units may be pulled from within the shields. The platform further includes a system for removing the mined ore from the transfer units as it is delivered from the mine.

  • Publication number: 20040245845
    Abstract: A mining system for remotely mining ores and minerals which protects against falling rock and allows evacuation of a miner and conveying system in the case of a cave in. A shield is advanced into a mine. Within the shield, the miner and conveying system are also advanced into the mine independently from the shield. The shield may be used with miners and conveying systems in common use. The cover of the shield protects the miner and conveying system from falling rock. In the event of a cave in, the shield provides a cavity for safely removing the conveying system and miner from the mine.
