What are the six major systems in mines?
The six major mine systems are the core components of coal mine production safety, covering key functions such as monitoring and control, personnel positioning, emergency avoidance, pressure wind self-rescue, water supply rescue, and communication. Together, these systems form a mine safety protection network, which effectively reduces the risk of accidents and ensures the safety of miners. The following are mine safety topics and related structured data that have been hotly discussed across the Internet in the past 10 days:
1. Overview of the six major systems of mines
| System name | Main functions | technical standards |
|---|---|---|
| Monitoring monitoring system | Real-time monitoring of gas concentration, wind speed, equipment status, etc. | AQ6201-2019 |
| Personnel positioning system | Track the location of miners and record their movements | AQ1048-2007 |
| emergency avoidance system | Provide temporary shelter and emergency supplies | AQ2033-2011 |
| Pressure wind self-rescue system | Providing clean breathing air during disasters | AQ2013-2008 |
| water supply rescue system | Emergency water supply and clean water source protection | AQ2014-2008 |
| communication liaison system | Real-time communication between surface and underground | MT/T1115-2011 |
2. Analysis of recent hot topics
1.Speeding up smart mine construction:AI technology has been promoted in many places to empower mine monitoring systems to achieve automatic early warning of gas overruns.
2.Controversy over personnel positioning accuracy:An accident in a coal mine exposed a blind spot in UWB positioning technology, triggering discussions on industry technology upgrades.
3.New rules for emergency drills introduced:The State Administration of Mine Safety requires that six major system linkage drills be conducted at least once a month.
3. Typical cases of technology application
| Coal mine name | Innovative applications | effectiveness |
|---|---|---|
| A mine in Shanxi | 5G+VR remote monitoring | Troubleshooting efficiency increased by 40% |
| A mine in Shaanxi | Laser Methane Monitor | Gas detection accuracy reaches 0.01% |
| A mine in Inner Mongolia | Intelligent escape cabin | Autonomous oxygen supply extended to 120 hours |
4. Industry development trends
1.Multi-system integration:In 2024, we will focus on promoting data interoperability between monitoring and personnel positioning systems.
2.Domestic replacement:The domestic production rate requirement for key sensors has been increased from the existing 75% to 90%.
3.Emergency response upgrade:The new standard requires that the hazard avoidance system must contain more than 3 days of survival material reserves.
5. Frequently Asked Questions
| question | Answer |
|---|---|
| System construction cycle | Medium sized mines usually take 6-8 months |
| Maintenance cost | The average annual investment accounts for about 15%-20% of the total investment in coal mines |
| Acceptance criteria | Must pass on-site inspection by provincial safety supervision department |
With the advancement of science and technology and the strengthening of supervision, the six major systems of mines are developing in the direction of intelligence and integration. Data from recent industry conferences show that national coal mine safety investment will increase by 12% year-on-year in 2023, of which 35% will be used for the upgrading and transformation of six major systems. In the future, technologies such as the Internet of Things and big data will further strengthen mine safety assurance capabilities.
