Division 1 explosion proof light in coal mine safety lighting applications
First, why do you have to choose professional Division 1 explosion proof light in coal mines?
In the special environment of coal mining, explosion-proof lights have become a rigid demand to ensure production safety. According to the International Mine Safety Association [IMSA] 2023 annual report shows that 35% of the world’s underground accidents and lighting system failure there is a direct correlation.
Traditional lighting equipment in the methane concentration of more than 5% of the confined space, only 0.02 Joule electric spark can trigger an explosion, which is the fundamental value of the existence of professional explosion-proof lights.
Coal mine Division 1 explosion proof light must be approved IECEx/ATEX double certification, its explosion-proof structure using triple protection mechanism:
Explosion-proof shell: 8mm thick aluminum alloy shell can withstand 15MPa explosion pressure
Intrinsically safe circuit: limit the circuit energy below the minimum ignition energy
Increased safety protection: the fundamental joint surface precision machining to 0.05mm tolerance
Second, intelligent Division 1 explosion proof light technology breakthrough: from the cornerstone lighting to digital mining
Modern explosion-proof lights have broken through the traditional lighting category, in Shanxi Yangquan Coal Group intelligent transformation, equipped with 5G module Division 1 explosion proof light and lanterns to implement:
Real-time collection of temperature and humidity in the working face, gas concentration data automatically adjust the 3000-6500K color temperature to adapt to different operating scenes approved Mesh networking to build underground positioning system [accuracy of ± 0.5m].
Third, the golden rule of coal mine Division 1 explosion proof light selection: 5 fundamental indicators
1. Explosion-proof grade certification: must hold Ex d I Mb certification [China Coal Safety Mark + international certification].
2 optical performance configuration: advocating the choice of 120 ° wide-angle lens + anti-glare design machinery
3. Protection: Impact resistance must reach IK10 [5 Joule impact test]. 4.
4. Emergency lighting system: automatic switching of lithium iron phosphate battery power supply after power failure.
5. Convenience of maintenance: modular design helps high-speed disassembly and assembly underground [average maintenance time <15 minutes].
Inner Mongolia Ordos a coal mine measured data show that the use of new LED explosion-proof lights:
Lighting energy consumption reduced by 67% [annual electricity savings of more than 2.8 million yuan] equipment failure rate decreased by 82% roadway inspection efficiency increased by 45
Fourth, Division 1 explosion proof light installation and maintenance of the whole process specification
According to GB 3836.15-2017 guidelines, explosion-proof light installation must be followed:
Pre-embedded parts load-bearing test [1.5 times the safety factor] cable introduction device secondary blocking [using Ex special sealant] regular maintenance of explosion-proof surface [quarterly detection of the gap between the joint surface].
Common Maintenance Mistakes Warning:
× Wiping the explosion-proof glass with ordinary cleaners.
× Replacement of non-original light source modules without authorization
× ignore the grounding resistance test [should be <4Ω].
Fifth. Global coal mine lighting development momentum: Division 1 explosion proof lamp technology revolution
The International Mining Complex 2024 [IMC] reveals three major directions of innovation:
Self-supply energy system: integrated vibration power generation device, using the energy of the passage of mine cars
Digital twin application: each Division 1 explosion proof light laying 3D operation and maintenance models
Intelligent Spectroscopy: Approving light wavelengths to detect changes in gas concentration.
A multinational mining group measured cases show that the adoption of AI explosion-proof light system:
Equipment lifecycle extended to 80,000 hoursPreventive maintenance accuracy increased to 92%Accident rate related to underground lighting zeroed out
