    摘要: The present disclosure relates to a mining machine adapted for extraction of material from a deposit and a method for controlling operation of such a mining machine. According to an embodiment, the mining machine includes a data handling unit and a control unit. The data handling unit is arranged to receive, from an external storage medium, a data file representative of a user-defined cutting path, and to send, to the control unit, data corresponding to a cutting path selected among the user-defined cutting path and one or more machine-predefined cutting paths. The control unit is configured to control operation of the mining machine using an automatic cutting cycle in accordance with the selected cutting path corresponding to the data received from the data handling unit.

    摘要: Various examples are provided related to methane detection in harsh environments. In one example, a method includes drawing a sample of air from at least one first location; delivering the sample to a volume within a sensor block at a second location, where the sensor block includes a gas concentration sensor in communication with the volume; and where a vacuum is applied to the volume within the sensor block to facilitate delivery of the sample to the second location. In another example, a system includes a sampling unit that houses a sensor block, where a sample tube is coupled to an inlet of the sensor block, which includes a gas concentration sensor; an ejector that facilitates delivery of a sample of air from the first location via the sample tube; and a control unit that can receive a gas concentration sensor output from the sampling unit for processing.

    摘要: A cable handling system for a longwall mining machine is disclosed. The longwall mining machine includes a shearer configured to move along a pan line to mine material along a mine face. The cable handling system includes a service line configured to carry one or more supply lines to the shearer for facilitating shearer operation. Further, a plurality of interconnected trays accommodates the service line. Moreover, a controller is configured to determine a profile of the pan line; detect one or more parameters associated with the service line in relation to the profile of the pan line; and determine a likelihood of at least a portion of the service line dislodging from the plurality of interconnected trays based on the one or more parameters exceeding a predefined threshold.

    摘要: A roll of grid material for mine roof support, and a mining machine in combination with such a roll, in which the roll has bands of adhering material injected or otherwise forced into the roll in spaced locations along the roll's width. The adhering material interconnects the overlapped layers within the roll and is sufficiently strong to hold the grid material in the rolled configuration for transport and storage, and yet is readily pulled apart in response to sufficient manual or mechanical pressure applied against the roll, or tension applied to the unwound portion thereof, so as to enable the grid material to be incrementally unwound and installed in the mine. The rolls can be installed using a range of mining machines without need for any specialized dispensing or other apparatus mounted on the machine and without the need for any mechanical device to control unwinding.

    摘要: A method and apparatus for preventing the unexpected loss of heavy mining equipment by detecting the separation of heavy metal parts at an early stage in the separation process, and providing a warning signal in response to which the particular machine that is having the difficulty may then be shut down in a timely manner. A spring-loaded switch is sandwiched between the heavy metal parts, which upon partial separation of the parts then expands and turns on an electrical switch to activate a radio transmitter, sending an alarm signal to a receiver at a remote location.

    摘要: A pre-bolting system for underground mines which comprises narrow, deep slots in the working face and in drilling through at an angle and bolting from inside these slots with equipment specially designed for this purpose. The drilling, bolting equipment uses high pressure water to assist drilling by water jet. The bit can also be driven by an axial water turbine of small diameter located at the bit. The equipment includes a ventilation system to dilute gas inside the slot when drilling or bolting.
