  • Microseismic safety monitoring system
    Microseismic safety monitoring system
    1. Product description Monitoring and imaging system of Wantai microseismic, the microseismic monitoring and imaging product which integrates microseismic monitoring and imaging, data processing, data analysis and early warning is mainly composed of hardware system, software system, data analysis and interpretation system, and early warning system. The system is digital, intelligent and high resolution monitoring system. The real-time waveform data of microseismic events were collected, processed and analyzed by vibration sensor, and the stability of rock mass was monitored by spatial visualization. By capturing the precursor information of rock burst and collapse disaster, obtaining the location, energy and apparent volume of fracture zone, the mechanism of rock mass damage and fracture evolution and the early warning and control of rock burst disaster are studied. Hardware components of microseismic monitoring system,It is composed of microseismic sensor, microseismic data acquisition instrument, equipment power supply system and data transmission system. The microseismic sensor is responsible for collecting high quality waveform signals, and the microseismic data acquisition instrument converts the high quality waveform signals into data signals through a / d. The power supply system ensures the power consumption of the whole system, and the data of the system is transmitted by the data transmission system. 2. Product advantage Hardware system with low background noise (less than 0.2uvrms@2ms) Software system has advanced micro-seismic location algorithm Support microseismic event double difference imaging Supporting acousto-optic early warning for microseismic systems Selection of Multi-type Channel microseismic system (combination), 3/6/12/24 Channel System supports dual system operation, windows,linux system Support customizing to customer needs 3. Application area 1)Coal mine roadway advance detection system with excavation Coal mine roadway is the throat of safety production. It has the characteristics of long length, many construction sites and frequent safety accidents. In the process of roadway excavation, adverse geological bodies in front of the roadway that may cause safety accidents, such as collapse column, water rich zone, gas enrichment area, etc. Roadway accident has become one of the most important threats to coal mine safety production, which seriously endangers coal mine safety production. Therefore, finding out the abnormal geological and fluid distribution in front of the excavation head in advance can make reasonable planning and targeted treatment in advance, and can effectively reduce or even avoid the occurrence of dynamic disasters. 2)Tunnel excavation imaging and safety dynamic monitoring system Tunnel detection can provide the coordinates, shape and water content of adverse geological bodies in front of the work, and can obtain the relevant information of possible disasters such as water inrush, mud inrush, col...
  • Mine 5G wireless communication system
    Mine 5G wireless communication system
    1. Product overview Coal mine underground communication system is an essential facility for mine safety protection and production scheduling. It is an important part of mine information, intelligence and safety production management. Applying wireless communication system technology to coal mine enterprises, improving the level of underground wireless communication, accelerating the development of underground communication, and building an effective information platform for coal mine safety production, improving production efficiency and improving the management level of enterprises has become an important task for the development of coal mine wireless communication. Due to the poor underground environment, more roadway distribution and more interference signal sources, there are great obstacles to the development of wireless. With the advanced management concept of coal mine and the design concept of unmanned and less populated coal mine, the 5g multi base station wireless communication system of coal mine aims to provide good technical conditions and guarantee for the safety production of coal mine. 2. System function The system is connected to the operator's network, connected to the base station equipment through the operator's transmission network, set up several base stations underground, extend the network in a wireless way, and realize the functions of production scheduling management and information exchange on the well and underground through wireless communication means. The application of 5g technology provides a common platform for coal mine intelligence, positioning, monitoring and management, digital video monitoring and the collection, transmission and comprehensive processing of various underground sensor data, and provides a good application foundation for the integration of voice, positioning, video and data, production scheduling, emergency rescue, safety monitoring and mining enterprise management. The system consists of underground mine flameproof repeater Z1, mine flameproof base station controller, mine flameproof repeater Z2, mine flameproof base station, mine flameproof DC regulated power supply, dispatching console and other equipment. 3. System characteristics 1)The public network and private network share a set of base station system, which has the advantages of simple configuration, convenient debugging and cost saving. 2)Support the connection of wired, 5g, WiFi 6 and other HD cameras, and realize the management applications such as underground video return and safety monitoring. 3)The unique ar glasses configuration greatly improves the pain points of industries such as the failure to effectively supervise the underground maintenance process, the cumbersome machinery of on-site inspection tasks, and the failure to effectively guarantee expert support. 4)The system is equipped with high, medium and low 5g mining intrinsically safe mobile phones to easily realize underground photography, camera, recording, emergency ...
  • The comprehensive dust removal rate of Wantai dust collector reaches over 85%!
    The comprehensive dust removal rate of Wantai dust collector reaches over 85%!
    The dust collector RESARCH & DEVELOPMENT of Wantai Group is suitable for dust reduction in excavation working faces, coal mining working faces, underground tunnels, drilling operations, shotcrete operations, blasting operations, and other places. The dust collector does not require electrical energy. It uses underground static water and compressed air to drive the impeller to rotate at high speed, forming a negative pressure to suck in the surrounding dusty air and enter the air duct for wet filtration to achieve the purpose of dust reduction. After years of practical use in mines, the comprehensive dust removal rate has reached over 85%, and the dust reduction effect is obvious. It is a sharp tool for coal mine dust control and protecting the health of miners. The KJS series mining pneumatic wet dust collector (formerly known as the KJS series mining air water linkage dust collector) is designed for dust removal in drilling operations, shotcrete operations, excavation work surfaces, and other places. The dust collector is placed next to the drilling rig and shotcrete mixer, and the machine body and belt discharge points are convenient for underground installation. Only high-pressure water pipes need to be inserted at the filter inlet, and the filter outlet is connected to the inlet joint of the dust collector through high-pressure rubber pipes, The compressed air is connected to the air inlet. Open the high-pressure water valve and air pressure valve to control the operation of the equipment.
