摘要： A Tunnel Digging Machine (TDM) is a shield machine to excavate tunnels with almost any desired cross sections including rectangular, square, sub/semi-rectangular, sub/semi-square, horseshoe/U-shaped, elliptical, circular, sub/semi circular and such sections through a variety of soil and rock strata. The TDM can be designed to dig through anything from hard rock to sand with large range of width and height configurations. The TDMs can limit the disturbance to the surrounding ground and produce a tunnel lining. The TDMs may be used as an alternative to the current conventional Tunnel Boring Machines (TBM) or continuous miners. The major advantage of the TDMs over the TBMs will be their higher speed (higher advancement rate), fully sealable face, flexibility in the desired cross-section and reduced construction costs due to the mentioned higher speed, efficiency and optimized cross-section.

摘要： A cutting assembly for a mining machine includes a central hub having at least one arm extending radially outwards from the central hub. The arm includes at least one cutting means carrier movably arranged for radial movement along the arm and a primary actuator configured to control the radial position of the cutting means carrier. The cutting assembly further includes a locking means movable between an unlocked and a locked position, wherein the locking means in its locked position locks the cutting means carrier to the arm such that radial movement of the cutting means carrier is prevented. The locking means includes at least one locking member provided on the arm such that the locking member is movable between an extended position and a withdrawn position. The locking member in the extended position extends to engage the cutting means carrier such that movement of the cutting means carrier is prevented.

摘要： A rapid construction method of pipe jacking for underground rescue tunnel with large section is disclosed. The present invention realizes rock breaking through the cutting head of a roadheader cutting unit, and pushes pipe jacking forward through a pushing thruster. During the process, a protecting bush fixedly connected with a stretchable part is adopted for circumferential support; and since the cutting head and the protecting bush occupy the rock breaking space, and the pushing thruster pushes pipe jacking forward to push the coal rock in the annular space to the circumferential direction, the effect of moving forward without slag discharge can be achieved. The present invention can establish a rescue tunnel quickly and effectively, which saves rescue time and greatly reduces the threat to the life safety of trapped people. The present invention can establish a fast and safe underground rescue tunnel with large section for the rescue of people.

摘要： A tunnel boring machine includes: a shield body; a cutterhead assembly, a first drive mechanism; a second drive mechanism; and a third dive mechanism. The cutterhead assembly includes a main cutterhead and a plurality of auxiliary cutterheads. The main cutterhead is rotatably arranged at a front side of the shield body and defines a soil chamber between the main cutterhead and the shield body, and is movable along an up-down direction. The plurality of auxiliary cutterheads are rotatably arranged in the soil chamber, and adjacent to a bottom of the shield body and arranged at left and right sides of a vertical central line of the main cutterhead. A rotation diameter of the main cutterhead is greater than a rotation diameter of the auxiliary cutterhead, and the rotation diameter of the main cutterhead is the same as a maximum width of the shield body.

摘要： A longwall mining system includes at least one face end roof support having a longitudinal length, and at least one near end roof support adjacent the face end roof support. The near end roof support has a longitudinal length substantially shorter than the face end roof support longitudinal length. There is also at least one face roof support adjacent the near end roof support, and the face roof support has a longitudinal length substantially shorter than the near end roof support longitudinal length. There is also a forward conveyor extending forward to and attached to the face end roof support, the at least one near end roof support, and the at least one face roof support, and a rearward conveyor extending rearward of and attached to the face end roof support, the at least one near end roof support, and the at least one face roof support. This creates an effective cave line at an angle to the coal face, that helps reduce the goaf pressure on the face end, thereby increasing the stability of the main gate roof support.

摘要： The present invention provides a door arrangement for a tunneling machine. The door arrangement is for location at the front of the tunneling machine adjacent to the digging end of the machine. The door arrangement allows for the interior of the machine to be sealed off from the tunnel face, while also allowing for the door arrangement to be opened and allow complete access to the tunnel face. The door arrangement comprises door sections for hinged connection to a tunneling machine, the door sections being pivotable about the hinged connection between a closed position sealing the tunneling machine and an open position allowing the tunneling machine access to a tunnel face.

摘要： 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.

摘要： An arrangement for detecting the state of rotation of cutting rollers (2) of a shield tunneling machine has at least one cutting roller (2) comprising a generator unit (12) that generates electrical energy when the respective cutting roller (2) is rotating, a signal-generating unit (16) connected to the generator unit (12), and an antenna unit (17) connected to the signal-generating unit (16). The signal generating unit (16) serves to generate transmission signals characteristic of the state of rotation of the respective cutting roller (2). An antenna (20) of the antenna unit (17) is disposed over at least one outer circumferential portion of the respective cutting roller (2) and is equipped for the wireless transmission of the transmission signals. The arrangement further comprises a receiving unit equipped to receive the transmission signals and interpret them regarding the state of rotation of the respective cutting roller (2). In this fashion, given the autonomous nature of the energy supply to the signal generating units (16) disposed in the cutting rollers (2), the state of rotation of the cutting rollers (2) can be monitored wirelessly from, for example, a control booth of the shield tunneling machine.
