Исполнительный орган очистного комбайна

Номер: RU0000175449U1
Автор: Виктор Васильевич Габов, Денис Александрович Задков, Кхак Линь Нгуен
Принадлежит: федеральное государственное бюджетное образовательное учреждение высшего образования "Санкт-Петербургский горный университет"

Полезная модель относится к горному машиностроению и служит для повышения эффективности погрузки угля на конвейер увеличением размеров площади сечения погрузочного окна и размеров зоны погрузки. Исполнительный орган выполнен в виде поворотной рамы, представляющей собой две боковые балки, жестко соединенные с одной стороны втулкой, а другой стороны балки жестко соединены корпусом привода исполнительного органа, при этом одна завальная балка конструктивно выполнена в виде ребер жесткости корпуса редуктора шнека и расположена над завальным бортом конвейера, а вторая забойная балка выполнена в виде дополнительной подшипниковой опоры приводного вала к шнеку и расположена над забойным бортом конвейера, при этом нижние поверхности балок выполнены вогнутыми вверх, ступица шнека выполнена конусной с уменьшением диаметра к погрузочному окну, а забойная балка выполнена с сечением, меньшим, чем сечение завальной балки. Технико-экономическая эффективность технического решения заключается в увеличении объема погруженного угля на конвейер в единицу времени как при рабочем ходе комбайна в процессе добычи, так и при холостом ходе комбайна с зачисткой почвы, т.е. в увеличении максимальной производительности комбайна, снижении измельчения угля при погрузке и удельного расхода энергии на погрузку угля.

An apparatus for acquiring repeatable and trendable performance data for monitoring the health of an articulating machine includes sensors, a programmable logic controller, a machinery monitoring system, and a display device. The sensors collect performance data as the machine performs prescribed motions. The programmable logic controller includes memory for storing motion predicate values that indicate motion conditions to be achieved as predicates to analysis of performance data as the machine performs the prescribed motions. A processor in the programmable logic controller compares the performance data to the motion predicate values to determine whether the motion conditions are being achieved as the machine performs the particular prescribed motion. A processor in the machinery monitoring system calculates analysis parameter values that indicate the health of the machine.

A method of operating coal mine machinery that protects and maintains machine operators' health and well-being removes the machine operators to a clean, low-noise environment inside a refuge chamber. Inside, are controls, cameras, audio, and informational displays needed to run continuous mining machines nearby and communicate mine-wide with other personnel. Cameras fitted to the mining machines provide straight-ahead views, ground penetrating radars fitted to the cutting drums measure the coal depths in the ceilings above, the floors below, and the coal face ahead. Guidance data is presented on informational displays, and the data from the ceilings and floors is used to drive computer graphics special effects to graphically represent the coal ceilings and coal floors overlaying boundary rock. Audio pickups on the mining machine allow the operator to hear and feel how the machine is functioning, just as operators have always employed their other senses. 1. A method of operating coal mine machinery that protects and maintains machine operators' health and well-being , comprising:removing coal mine machine operators from unlimited noise and float coal dust exposures alongside a coal mining machine to inside a less noisy and relatively float coal dust-free environment inside a nearby refuge chamber;video imaging the view ahead of the coal mining machine with a camera mounted to it and providing a video link to a user display inside the refuge chamber;engaging the coal mining machine operators in an immersive experience and virtual reality video display on a horizontally projected concave three-dimensional (3D) vision dome;preventing mining-out-of-seam by displaying to the coal mine machine operators a computer generated graphic and informational display included in the user display of a boundary-layer coal thickness computation derived from a ground penetrating radar measurement provided by a resonant microstrip patch antenna (RMPA) attached to a coal cutting drum of ...

Roof support monitoring for longwall system

Номер: US20170335688A1
Автор: Kirabo Kiyingi, Nigel J. Buttery, Paul M. Siegrist
Принадлежит: Joy MM Delaware Inc

A monitoring device and method for monitoring a longwall mining system having a roof support, the roof support including a pressure sensor to determine pressure levels of the roof support during a monitoring cycle. Pressure information is obtained for the roof support. An electronic processor then determines whether the pressure information is indicative of a first type of pressure failure of the roof support and whether the pressure information is indicative of a second type of pressure failure of the roof support. An alert is generated in response to determining that the pressure information is indicative of at least one selected from the group consisting of the first type of pressure failure and the second type of pressure failure.

SYSTEMS AND METHODS FOR MONITORING LONGWALL MINE ROOF STABILITY

Номер: US20160362980A1
Автор: Knuth Jason

Systems and methods are described for monitoring a condition of a mine roof using a longwall mining system. A plurality of powered roof supports is controlled to apply an adjustable support pressure on a mine roof. A condition of the mine roof is monitored based on the adjustable support pressure applied to the roof by a respective actuator of each powered roof support. In some implementations, the condition of the mine roof is monitored by generating and analyzing a graphical pressure map based on the adjustable support pressure applied by each powered roof support and a relative position of a shearer moving across the mine face. In some implementations, roof collapse events are detected based on temporally similar changes in the adjustable support pressure applied by multiple adjacent powered roof supports as indicated by the graphical pressure map. 1. A longwall mining system comprising:a plurality of powered roof supports, each powered roof support including a controllable hydraulic piston configured to apply an adjustable support pressure on a mine roof; and receive data from each powered roof support of the plurality of powered roof supports indicative of fluid pressure within each respective controllable hydraulic piston, and', 'monitor a condition of the mine roof based on changes in the received data over a period of time., 'an electronic control unit configured to'}2. The longwall mining system of claim 1 , further comprising a shearer configured to move across a mine face as the plurality of powered roof supports are arranged in a series along the mine face claim 1 , a plurality of parallel display lines each providing an indication of fluid pressure within a different one of the controllable hydraulic pistons of the plurality of powered roof supports over the period of time, and', 'a shearer position line indicative of a position of the shearer relative to the plurality of powered roof supports over the period of time overlaid onto the plurality of ...
