Who says there is no sky underground? Safe production is the sky-"nickel capital", "safety economy" of Jinchang, Gansu mining underground
As soon as it was bright, 35-year-old Yang Guohui led the production team of the Second Mining Area of Jinchuan Group to finish the task for the day, and then all stood up and swore: "Construction in accordance with the standard, operation in accordance with regulations, personal self-discipline, to prevent 'three violations' and ensure safety".
The mining area with 24-hour production ushered in another day in the severe cold. Workers wore work clothes with silver reflective strips, and the commuter car traveled up the mountain to a wellhead with an altitude of more than 1,800 meters. Every day, more than a thousand workers took the cage down to a mining operation area nearly a thousand meters above the ground.
Jinchuan Group, located in Jinchang City, Gansu Province, has the third largest copper-nickel sulfide deposit in the world. In the past 60 years, Jinchuan Company has grown into the largest nickel-cobalt production base in China. The second mining area is the main mine of Jinchuan Group. It is estimated that 4.25 million tons of underground mining will be completed in 2019.
The safety production protection measures here are in the leading position in the industry, but the safety protection awareness has never been lax. "Underground is changing at all times. Now it looks good. Once blasting, there will be changes in safety." Yang Guohui once again stressed the need to operate safely. The first step in safe work on site is to “check the skid”. Workers held aluminum crowbars to beat and search for cracks and knocked loose ore to prevent accidents.
Under the mine in the second mining area, the roadways criss-cross, just like the urban road network. Rock drilling rigs drill holes, load explosives, detonate, and scrapers pull the ore to the chute-the mining area will follow this process to mine out, day after day. Surveillance can be seen everywhere in the aisle, just like electronic police capture traffic violations.
13 years ago, Yang Guohui went down for the first time and was arranged to drill a rock platform. Everything there was strange, "I felt dangerous at first and had a psychological burden." He saw the winding coiled tubing and the various operating handles, thinking it was too complicated, just a monster.
To tame a "monster," you must first understand it. It took Yang Guohui almost two years to learn to independently operate the rock drilling rig and master the drilling technology. The "monster" is no longer ferocious. "Knowing where it is dangerous, we have precautions," he said.
During his ten years as monitor, Yang Guohui spent more than 280 days in the well each year. In 10 years, there was no safety incident in the team he led. Since 2015, he has led the production team to accumulate more than 3.29 million tons of underground mining. The mobile step counting software showed that he took at least 20,000 steps per shift.
To all security measures, Yang Guohui is treasured. For example, the scraper body and bucket are too large, affecting the driver ’s sight. In order to prevent injuries to the vehicle, all personnel must be evacuated when the mine is out; Whistle flashing warning first; steel plates are mounted on the boots to prevent falling stones from hurting the insteps ...
Walking through the lane, Yang Guohui's bracelet suddenly shook. He reminded everyone to pay attention to avoiding. At this time, a scraper also stopped at a short turn and the alarm light flashed. Yang Guohui raised his wrist and said that this is the anti-collision device that has just been equipped this year. In the past, when the car rang, pedestrians relied on flashlights to shake the lane to remind the driver. Now the electronic bracelet can sense the warning in time, which is more convenient.
Yang Guohui's team has a consensus: When it comes down, safety is heaven. With the "1" of "security", the following "0" is meaningful.
There is no sunlight downhole, the environment is closed, and the noise is loud. Yang Guohui was used to speaking loudly, his voice was too low to hear, and his voice was loud when he returned home.
"No one thinks you care much, it's all for everyone to go to work safely and safely," he said.
At 8 o'clock in the evening, Yang Guohui was still cleaning up the job site with colleagues. "The scene must be kept clean, and the tail cannot be reserved for the next shift." He had to get up to work again at 6 am, and there was something he was worried about at the thousand-meter underground operation site. For this reason he has never been able to send his 8-year-old daughter to school.
