摘要： The present invention relates to a warning device for a mining control module for facilitating a replacement. Accordingly, a warning device for a mining control module is suggested, which comprises a housing that is configured to be coupled with an opening provided at an outer surface of the control module, wherein the housing defines an inner cavity, and an alarm module which is arranged in said cavity and is configured to be releasably coupled to an inner control unit of the control module via said opening for receiving a control signal. The housing comprises a first portion that extends along a longitudinal axis and is configured to extend at least in part through the opening and a radially extending second portion that is configured to extend over the outer surface of the control module so as to cover the opening, when the device is coupled to the control module. The device furthermore comprises a fixation means, which is arranged on the second portion and is configured to releasably engage the outer surface of the control module so as to secure the device to the control module.

摘要： A conveyor pan for a chain scraper conveyor comprises a bottom plate and a pair of side profiles fixed to the bottom plate by welding. The conveyor pan has an increased wear resistance, in particular due to a specific geometry of a weld groove formed between the profile rails of the side profile and the bottom plate. The weld groove extends deeper into each profile rail, resulting in a more durable weld connection during use of the conveyor pan. In addition, a geometry of a pocket member for connecting adjacent conveyor pans and an inspection opening formed in the bottom plate have also been improved to result in an increased strength of the conveyor pan.

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 self-advancing roof support for a longwall mining system includes a base, a hydraulic actuator having one end pivotally coupled to the base, and a canopy portion that is connected to another end of the hydraulic actuator. The roof support also includes a load sensor disposed on the canopy portion. The load sensor generates a signal indicative of an amount of load borne by the canopy portion in abutment with a roof of an underground mine site. A controller is communicably coupled to the load sensor and the hydraulic actuator. The controller determines if the signal from the load sensor is suggestive of a cavity adjacent to a zone above the canopy portion. Based on the determination, the controller actuates movement of the hydraulic actuator such that the canopy portion is displaced into a position underlying the cavity.

摘要： A system for monitoring a condition of a pan line associated with a longwall mining system includes multiple pan segments arranged in a successive manner. Adjacently located pan segments are moveably coupled by an interconnecting joint. An underside of each pan segment defines an opening whose axis is parallel to a plane of the associated pan segment. The system also includes a fiber optic shape sensing system that has a fiber optic cable disposed along the multiple pan segments and located within the opening of each pan segment. A controller coupled to the fiber optic cable detects a shape of the fiber optic cable, identifies a position of each pan segment based on the detected shape of the fiber optic cable, and determines if a fault exists in the interconnecting joints between adjacently located pan segments based on the identified positions of respective ones of the adjacently located pan segments.

摘要： An implement system for a machine includes a boom housing a drive mechanism for a cutting implement, and having a plurality of oil outlet ports formed therein. A control mechanism is configured to receive data indicative of an expected change in location of the outlet ports relative to an oil fill line within the boom, and vary a pattern of incoming oil flow to limit entrainment of air in the oil.

摘要： A milling depth compensation system for milling rock determines a target position of a machine, an initial position of the work surface, and a target pose of the machine based on the target position of the machine and the initial position of the work surface. An actual pose of the machine is determined and differences between the actual pose and the target pose are used to determine a dynamic milling path of a milling tool. The dynamic milling path includes movement of the milling tool along a first path, a second path, and a third path. Command signals are generated to move the milling tool along the dynamic milling path.

摘要： A site positioning system for an underground machine includes a first prism coupled with the underground machine, a second prism operatively coupled with the underground machine, a primary total station, and a reference prism may be in communication with the primary total station. A positioning controller is configured to control, responsive to receiving a High Accuracy Machine Position mode, the primary total station to monitor the first prism and the second prism and transmit a first prism position and a second prism position, respectively, to the positioning controller; control, responsive to receiving a Low Accuracy Machine Position mode, the primary total station to monitor the first prism and transmit the first prism position to the positioning controller; determine, responsive to receiving a Reference Prism Measurement mode, whether a reference prism measurement has been completed, and present positioning information for the machine based on one or more of the prism positions.

摘要： A machine for cutting material includes an undercarriage including propulsion device for propelling the machine and a cutter head disposed on a tool support and positioning assembly movably supported by the undercarriage to remove material from a cutting surface. The machine further includes a plurality of ground-engaging devices connected to the undercarriage that can be simultaneously raised and lowered with respect to a ground floor. Examples of ground-engaging devices include stabilizers for stabilizing the machine when milling or cutting material and a load shield that prevents material from scattering underneath the machine.
