From a novice electrician
to a model worker of Shendong Coal Group
In 15 years
he has been working closely with electromechanical equipment
and has become a ‘diagnostic expert’ in electromechanical equipment
Today, let’s get to know
Shendong Buritai Coal Mine
Electromechanical Team Leader
Yang Jing
Yang Jing’s ‘Sixth Sense’
In his daily work
Yang Jing actively participates in the maintenance
and repair of electromechanical equipment
During a routine inspection
Yang Jing and his teammates
entered the Ming’anmu independent air shaft
main fan substation
As they passed the variable frequency drive in the main fan substation
a sudden sound
interrupted everyone’s actions
“At that time, we measured the data three times, and the instruments showed everything was normal. But Team Leader Yang stood on the insulated platform, constantly scanning the cooling fan of the variable frequency drive, touching the equipment and saying that the fan speed was unstable and the temperature was noticeably higher than last time. Sure enough, after disassembling and inspecting, we found slight metal fatigue cracks at the fan bearing,” recalled repair team leader Li Zhigang.
“Team Leader Yang’s ‘sixth sense’ has always been accurate!” said an employee nearby.
“What ‘sixth sense’? It’s all muscle memory accumulated over more than a decade.” As he spoke, Yang Jing was still simulating the arc of the fan’s rotation.
Identifying Problems and Solving ProblemsSticking to the old ways can only preserve for a moment
Innovation is the key to long-term preservation
Yang Jing takes this sayingas his motto
The key to safety production innovation in the team
lies in technological breakthroughs
Yang Jing’s technical determination is his distinctive label
Employees need to conductmultiple leakage tests
which consumes a lot of man-hours
and poses safety risks
In response,
Yang Jing secretly resolved
to break this situation with technological innovation
After repeated observation and contemplation
Yang Jing set the breakthrough point
on the control equipment
So he led everyone
to repeatedly study the
working principles, write programs, and test data
After multiple program rewrites and on-site debugging
they finally overcame the technical bottleneck of the control equipment
When the parameters reached the ideal state
and the entire system began to operate stably
everyone’s anxious hearts finally relaxed
However,
what makes Yang Jing truly proud
is still the “crystal palace” of cables
in the 12 upper three plate area
During the day and night of creating standardized cable trenches
Yang Jing led the technical team
to work overtime designing plans
expanding the traditional 1-meter-wide cable trench
to 1.3 meters
This seemingly simple change
finally gave various lines a neat ‘home’
When they eagerly tested the acrylic cover of the cable trench, a new problem arose – although the transparent material made the line conditions clear at a glance, the slight elastic deformation caused by walking made the maintenance personnel feel as if they were ‘walking on cotton.’
After observing, Yang Jing proposed replacing the acrylic board with tempered glass.Three days later, at the acceptance site, the tester stood on the glass cover for testing, and the sturdy cover remained motionless.
Through the glass cover
a row of high-voltage cables, low-voltage cables
and communication lines appeared neatly
with clear and visible labels
creating convenient conditions for troubleshooting
effectively avoiding safety hazards
From youthful years to the age of understanding
Yang Jing has dedicated his youth
to every piece of equipment and every cable
The light of coal miners
is not only underground
but also in their hearts
This light not only illuminates
Yang Jing’s path of progress
but also becomes the lamp that lights up the mine
