Helping Jiangzhuang Coal Mine to create a 'zero-accident' working environment with Hikvision's smart video technology
TENGZHOU CITY, China, Feb. 11, 2020 /PRNewswire-AsiaNet/ --

Mines are unique operating environments with highly specific health and safety 
challenges. In particular, underground mining operations typically experience 
low-visibility conditions and light pollution from flashlights, vehicle lights 
and reflective strips on equipment and clothing, making traditional 
surveillance and safety monitoring difficult.

These were some of the challenges facing Jiangzhuang Coal Mine in the Shangdong 
Province of China, which covers an underground area of 43 square kilometers, 
and produces more than 1.8 million tons of coal each year. The top priority for 
the mine's management team is worker safety, and working practices and 
production are monitored 24 hours a day to minimize accident risks. 

Kong Qingwei, Director of the Jiangzhuang Coal Mine Dispatch Office, says, "We 
need to respond immediately to unsafe situations in the mine, whether they are 
caused by environmental factors, poorly performing machines, or employees not 
following authorized work procedures."  

Although the mine invests heavily in safety training and equipment for workers, 
its aging surveillance system made health and safety monitoring difficult in 
key areas of the mine. "Our previous surveillance system required us to monitor 
around 30 screens, 24 hours a day, often with sub-optimal image quality caused 
by low-light conditions or light pollution," says Kong Qingwei. "This made our 
jobs extremely difficult and tiring, as well as impacting our ability to 
respond to safety issues quickly enough." 

Maximizing worker safety with Hikvision's intelligent video technology
To address its health and safety challenges, Jiangzhuang Coal Mine has 
implemented an intelligent video surveillance and control system from Hikvision.

The Hikvision solution supports crystal-clear video imaging, even in low-light 
conditions, or where light pollution is created by lights or reflective strips. 
This quality and clarity of imaging ensures that hidden risks can be identified 
more quickly and easily, allowing the safety team to respond more quickly and 
to protect workers in all areas of the mine.   

In addition to the improved imaging capabilities, the Hikvision cameras 
incorporate deep learning technologies to identify and respond to health and 
safety risks in the mine automatically, and in real time. Specifically, the 
cameras can identify when employees deviate from approved work procedures and 
send alerts to the safety team to ensure staff can be deployed before accidents 

For example, it is prohibited for workers to come too close to winches when 
they are working due to safety risks, but this is hard to monitor with 
traditional video cameras. "The new Hikvision system increases worker safety by 
monitoring the areas around winches and other equipment, and by sending alerts 
if employees get too close," says Kong Qingwei.

Improving worker health and safety with real-time, actionable insights
In the first three months of operation, the new Hikvision system identified 
more than 30 deviations from safe operating procedures. Zhang Liu, Deputy Chief 
Engineer at Jiangzhuang Coal Mine, says, "In the past, many of these safety 
risks could have gone unnoticed. However, the Hikvision system has allowed us 
to identify every incident in real time and to take immediate action to protect 
our workers, which is a hugely satisfying outcome for us."

Delivering continual improvement for safety procedures
As well as alerting the team to potential security risks in real time, the 
Hikvision system also records the details of any safety incident for later 

"As well as accurately capturing deviations from safe working procedures, the 
Hikvision system supports playback and download functions," says Zhang Liu. "We 
can use the insights we record to deliver continual improvement for safety 
procedures, and, ultimately, to support our vision for a 'zero-accident' mine," 
he adds.

Addressing mining-specific safety requirements 
The Hikvision solution is configured to support specific mining-safety 
applications, such as constant monitoring of surface water levels in different 
areas of the mine. 

"Constant seepage from rock formations means that surface water can accumulate 
in different areas of the mine, which is a problem in terms of potential 
flooding, damage to infrastructure, and worker safety risks," says Zhang Liu. 
"With the Hikvision system, we can manage surface-water levels constantly and 
take action to deal with any problems that arise before water levels exceed 
safe limits," he adds.

In addition to surface water management, the Hikvision solution supports 
improved safety in other potentially dangerous areas of the mine, including 
inclined tunnels that are used for transporting coal and other materials 
underground. "The Hikvision system is like an intelligent 'eye' for us in all 
areas of the mine, helping us to identify potential safety issues in a timely 
and accurate way and to protect our workers at all times," says Kong Qingwei. 

Increasing effectiveness for the safety team
With automated alerts for all manner of potential safety threats, the safety 
team can be far more effective, with no need to monitor video images 
constantly. "Instead of looking at grainy images on 30 screens, we can now 
spend more of our time responding to incidents, supporting workers, and keeping 
them safe," says Zhang Liu. "This is a classic example of how automation can 
help to improve mine safety, while also reducing the tiring workloads 
associated with manual monitoring of screens."
