The safety monitoring system currently used in Taiping Coal Mine of Shandong Lutai Coal Industry Co., Ltd. is the KJ76N-F coal mine safety monitoring and monitoring system produced by Zibo Ruiante Automatic Control Equipment Co., Ltd. The system was installed and used in February 2005 and was launched in 2006 Upgrade the system. The upgraded monitoring system can meet the requirements of the safety production industry standard AQ6201-2006 issued by the country and meet the requirements of the “Coal Mine Safety Regulations”. The system is now equipped with 1 host, 1 standby machine, 1 modem, 1 data transmission interface, 3 monitoring stations, 3 power supplies, 26 monitoring stations, 10 wind speed sensors, 33 methane sensors, and 8 carbon monoxide sensors. Taiwan, 6 sets of air duct sensors, 12 sets of air door status sensors, 2 sets of current sensors, 10 sets of feed sensors, 1 set of hooks, negative pressure, and coal level sensors.
The safety monitoring system includes sensors, underground sub-stations, transmission equipment, and ground central station, which respectively complete the functions of information collection, information transmission, information processing, and information output. Sensors include methane sensors, carbon monoxide sensors, wind speed sensors, feed sensors, equipment start and stop sensors, air door status sensors, temperature sensors, air duct sensors, negative pressure sensors, current sensors, coal level sensors, etc., which are used in coal mine safety monitoring systems Very important part. The underground substation collects the signals of each sensor, and after signal conversion processing, transmits it through the ground center station of the transmission equipment box; at the same time, the underground substation receives the instructions of the ground center station to complete the specified tasks, such as control output. Transmission equipment is the signal transmission medium of the monitoring system, including communication cables and modems. The function of the ground center station is to display various monitoring parameters in real time, such as gas, carbon monoxide, wind speed, and temperature; important parameters can be stored and can be recalled at any time and historical data can be reproduced in a variety of ways; when the monitoring parameter value exceeds the limit value, it will automatically alarm , And automatically switch to the emergency state, so as to realize the function of analyzing the environment state, and provide a basis for the leadership decision-making.
Underground personnel positioning system
The personnel positioning system currently used in our mine is the KJ225 personnel positioning system produced by Beijing Longde Times Technology Development Co., Ltd.; the system was installed and used in March 2008. The system is now equipped with 1 host and 1 standby machine, 1 modem, 1 data transmission interface, 6 KJ225F transmission substations, 6 power supplies, 24 KJ225S wireless receivers, and 1,600 KJ225K personal identification cards.
The personnel positioning management system is developed for coal mine enterprises to strengthen personnel management and ensure personnel safety. It can realize the underground attendance and real-time area assignment of underground personnel, and provide guarantee for the safety of underground personnel. The activation of the personnel positioning and attendance system will play a positive role in ensuring the safe production of our mines, improving the level of safety management, and further enhancing the ability of disaster prevention and relief.
Wireless communication system
The wireless communication system of Shandong Lutai Coal Industry Co., Ltd. Taiping Coal Mine is a KT23 system produced by Hangzhou Beichen Tiandi Communication Equipment Co., Ltd. The system is composed of central office equipment, mine wireless central controller, mine line extender, KTW13 mine base station, UT117 mine intrinsically safe mobile phone, mine flame retardant communication cable, etc. The current system is equipped with 30 KTW13 40MW base stations, 1 KTW12 wireless central controller, 1 KDW52 mine power box, 1 ESC-M7 dedicated 500MW base station, and 200 UT117 PHSs. The signal can cover the mine area and mine area. The main underground tunnels can cooperate well with dispatching telephones, and can play a supplementary role in the absence of dispatching telephones, ensuring normal communication.
Pump room automation control system and hydrological monitoring system
The system started to be installed in May 2008 and was developed by our mine in cooperation with Shandong University of Science and Technology based on the specific conditions of our mine. At present, one industrial computer, one PLC network controller, one control cabinet, various sensors, pressure gauges and electric actuator valves are installed. A total of 3 flow sensors and cameras were installed in the central sump, the sump of the 9 mining area and the drainage point of the 8 mining area. The system can monitor all-weather related parameters of mine hydrology and can realize the on-site and remote automatic control of the main drainage pump house in the Ethernet according to the requirements; it can realize data analysis, query, statistics, chart display and storage functions in the dispatch center and the pump house. Drainage automatic control; realize the monitoring target over-limit alarm. The system can be connected with the mine ring Ethernet system to realize online monitoring of mine hydrology and remote digital control. Due to the long-term threat of water hazards in our mine, this system can ensure that our mine knows the hydrological conditions of the site at any time, and promptly responds to the water hazard threat.
16-channel industrial TV monitoring system
In March 2005, our mine cooperated with Jinan Juyang Company to install industrial TV. As of June 2008, Jining Tianyi Company has upgraded it and adopted the Guangzhou Wetron DLP system to make the system more complete. At present, the system can monitor 16 points up and down the well for 24 hours, which improves production efficiency and guarantees Safe Production.
