Through the centralized control room monitoring screen, it is clear that the rolling coal flow begins to stretch on the kilometer belt. This is a vivid portrayal of the new technology for the remote monitoring and monitoring of belt transportation in the mine. The geological conditions under the Tian Chen mine are complex and the belt transport front is long. In order to save human resources and improve the efficiency of belt transportation, the technical backbone of the belt belt work area and the Beijing University of Mines jointly tackled the problem. Using PLC programmable control technology, the remote centralized control scheme for the downhole strong belt was successfully implemented, saving human resources and improving belt transportation. Work efficiency. In order to solve the problem that the underground coal bunk cannot be remotely monitored and the belt spray device relies on manual control, the mine uses the original remote data transmission line and PLC programmable control technology to install the coal level sensor and automatic solenoid valve on site. There are 3 new technologies, such as remote monitoring and alarming of underground coal bunker, remote automatic control of belt head spray, and voice safety prompt before belt start. This year, the vertical tear protection device for the downhole belt was invented. With the remote alarm function of the existing coal control, smoke, over-temperature, low-speed and deviation protection of the centralized control system, the safety monitoring and monitoring of the downhole belt was comprehensively improved. The belt is safely operated with a thousand eyes and a windy ear, which effectively restrains the unsafe factors such as belt full warehouse, silt coal, deviation, tearing caused by manual decentralized control. The centralized control driver can monitor the running status of the belt at any time in the ground control room, check the safe operating parameters of the belt, record the running log of the belt, and truly realize the warning of hidden dangers of accidents, so as to achieve advanced prevention. By implementing a new technology and model for remote monitoring and monitoring of belt transportation, it not only improves the safe running coefficient of the belt, but also greatly saves human resources. At present, the mine has promoted the application of this technology in 13 kinds of powerful belts in the underground, with a total length of more than 10,000 meters.
PPGI/PPGL(prepainted galvanized steel /prepainted galvalume steel )is also known as pre-coated steel,color coated steel, coil coated steel, color coated steel,pre pianted steel sheet,The PPGI steel coil/sheet made of cold-rolled steel sheet and galvanized steel sheet, subjected to surface pretreatment (degreasing, cleaning, chemical conversion treatment), coated in a continuous manner, and baked and cooled to form a product. Coated steel has light weight, beautiful appearance and good anti-corrosion performance, and can be directly processed.

New technology for remote monitoring and monitoring of underground belt transportation in Tianchen Mine
Night 11:06 27, dates Mining Group in Shandong Energy Tian Chen coal mine belt floor control room work area, industrial computer display: This area is responsible for the northern belt head fifty-three strong coal bunker coal-bit more than a third. Sun Xiujuan, the night-time centralized control driver, immediately called the underground patrolman Wang Cisu, and in real time issued a control command that “the coal bunker has reached the starting position and ready to start the transportâ€. Then she clicked the mouse and entered the running program, the ground. Simultaneously, the fire alarm signal is issued synchronously, and the belt head spray device of each belt is automatically opened 10 seconds ahead of time. After the entire north five strong belt system is started in sequence, the coal feeder starts to run...
