Ordos Hengtai Coal Co., Ltd. was established in 2005. It is one of the important coal production enterprises in Ordos City. Since its establishment, it has maintained a good safety production record. Recently, due to the update and upgrade of the production management and safety guarantee system, the company has conducted a unified bidding and procurement of equipment for the market, and the entire bidding process is open, transparent and fair.

Golden Samurai UPS power supply finally won the highest score in UPS power supply item with its product technical advantages, high cost performance and customized service plan. It is an honor to join Hengtai Coal Industry to escort Hengtai Coal Industry's safe production.

In addition to normal lighting, excavation, transmission, oxygen supply, and water supply, coal mine production must be equipped with the following six systems in accordance with the national coal mine safety production regulations: monitoring and monitoring, personnel positioning, emergency avoidance, self-rescue by pressure, water supply and rescue. Correspondence.

1. Coal Mine Safety Monitoring System

It is mainly used to monitor and early warning of gas, fire, and rock bursts and other serious accidents. The coal mine safety monitoring system monitors methane concentration, wind speed, wind pressure, feed status, damper status, air duct status, local ventilator start and stop, main ventilator start and stop, etc., when the gas exceeds the limit or the local ventilator stops running or tunnels into the tunnel When the wind stops, the power supply of the relevant area is automatically cut off and locked, and an alarm is issued at the same time.

The system also has functions such as coal and gas outburst warning, fire monitoring and warning, and mine pressure monitoring and warning.

The coal mine safety monitoring system generally consists of sensors, actuators, substations, power boxes (or electric control boxes), master stations (or transmission interfaces), host computers (including displays), system software, servers, printers, large screens, UPS power supplies, It is composed of remote terminal, network interface and cable. Sensors, actuators, sub-stations, power boxes (or electric control boxes), etc. are set in the well, and other equipment is set on the ground.

2. The position monitoring system of underground personnel in coal mine

The position monitoring system of underground coal mine personnel is also known as underground coal mine personnel positioning system and underground coal mine operator management system. The position monitoring system of underground coal mine personnel generally consists of identification card, position monitoring substation, power box (can be integrated with substation), transmission interface, host (including display), system software, server, printer, large screen, UPS power supply, remote It consists of terminals, network interfaces and cables.

The position monitoring system of underground coal mine personnel is used in the aspects of curbing over-capacity production, preventing personnel from entering dangerous areas, emergency rescue of accidents, timely detection of personnel who fail to raise the well on time, leading down-pit and shift management, special operation personnel management, underground operation personnel attendance, and certificate-holding management, etc. Plays an important role.

3. Mine communication system

The mine communication system is an important tool for coal mine safety production scheduling, safety avoidance and emergency rescue. The mine communication system includes the mine dispatch communication system, the mine broadcast communication system, the mine mobile communication system, and the mine disaster relief communication system.

Coal mines should be equipped with mine dispatch communication systems, and actively promote the application of mine broadcast communication systems and mine mobile communication systems. The rescue team shall be equipped with a mine disaster relief communication system.

4. Underground emergency avoidance system

Coal mines must equip personnel entering the well with self-rescuers with a rated protection time of not less than 30 minutes. The personnel entering the coal and gas outburst mine must carry an isolated self-rescuer, and the personnel entering the high gas mine should carry an isolated self-rescuer. The isolated self-rescuer should be a compressed oxygen isolated self-rescuer.

Coal and gas outburst mines should build refuge chambers (also known as hazard chambers) in the mining area. When the length of the excavation roadway of the outburst coal seam and the strike length of the coal mining face exceed 500 meters, the refuge must be built within 500 meters from the working face. Chamber or set up a rescue cabin.

For high-gas and low-gas mines, where within the rated protection time provided by the self-rescuer, it is impossible to safely evacuate to the ground from the mining face on foot, a refuge chamber or rescue cabin must be built within 1000 meters from the mining face.


V. Self-rescue system of mine compressed air

Coal mining enterprises must establish a compressed air system in accordance with the requirements of the "Coal Mine Safety Regulations", and on this basis, further improve the compressed air self-rescue system in accordance with the requirements of all mining and excavation sites to provide compressed air supply during disasters.

The air compressor of the compressed air self-rescue system should be installed on the ground. In deep multi-level mines, when the air compressor is installed on the ground and it is difficult to ensure effective air supply to the underground operation point, the air compressor can be installed in a safe and reliable position at the bottom of the air intake shaft at two levels above the air supply level. Protective measures should be taken for downhole compressed air pipelines to prevent catastrophic damage.

6. Mine water supply and rescue system

Coal mines must build a complete dust-proof water supply system in accordance with the requirements of the "Coal Mine Safety Regulations"; also set up water supply valves at all mining working faces and other places where people are concentrated to ensure that emergency water supply can be provided to each mining operation site during the disaster. . It is necessary to strengthen the maintenance of the water supply pipeline, ensure that the valve switch is flexible, and it is strictly prohibited to run, leak, drip, or leak.

The design and construction standards of Hengtai Coal Industry’s safety production management and guarantee system are strictly implemented in accordance with relevant national requirements and standards. The UPS power supply selected must have the ability to meet the harsh environment. At the same time, it must also meet the digitization of the coal mine safety production management system. For the need of intelligent upgrade, UPS power supply must have the following functions: advanced DSP digital control technology, large LCD+LED display screen, high-guaranteed dual AC power input function, frequency and phase sequence adaptive system, intelligent charging system , Excellent electrical performance, expandable parallel function and remote monitoring function.

Golden Samurai UPS power supply power frequency online series products can fully meet the functional requirements of Hengtai Coal Industry's power security system transformation and upgrade, and the excellent technical development and service team can ensure the product function upgrade required by Hengtai Coal Industry in the next few years. Expansion, such personalized service and high cost performance of the product, finally Golden Samurai UPS Power successfully joined Hengtai Coal Industry as its power supply for the transformation and upgrading of its power security system.
