By the end of June next year, the number of staff in high-risk places will be reduced by more than 30%.
For a long time, in key industries such as coal mines, metallic and nonmetallic mines, and dangerous chemicals, some enterprises have used a lot of labor in key links and key parts, and the degree of mechanization and automation is low, and the risk of mass casualties is high. The task of preventing serious accidents is arduous. "Development cannot be at the expense of safety. Mechanized substitution and automatic reduction of people are necessary for high-risk enterprises. " State administration of work safety Publicity and Education Center said. In 20 15, the state administration of work safety launched a special campaign of "mechanized substitution and automatic reduction of staff" in key industries, replacing manual operation with mechanized production and reducing manual operation with automatic control. By the end of June, 20 18, it is planned to reduce the number of staff in high-risk workplaces by more than 30%.
Replacing the first rope is an important work often carried out in friction hoisting mine. In a mine with a well depth of 760 meters in Erdos, Inner Mongolia, it takes 58 people to manually change ropes, which takes 102 hours. The service life of the first rope is 1.5 years, and the average annual cost is 2.4 million yuan. Intelligent rope changing and mechanical rope changing need 9 people and take 37 hours. The service life of the first rope is 2.5 years, and the average annual cost is 6.5438+0.3 million yuan. "In addition to saving time and efficiency, more importantly, through intelligent technological innovation, all workers in dangerous areas are replaced by machinery, and workers only need to do the work of connecting rope ends at the wellhead. The labor intensity is low, which eliminates the hidden dangers of workers working in the wellbore. " Jia, the relevant person in charge of Jiangsu Xuzhou University of Technology Sansen Technology Co., Ltd. introduced.
Mechanized substitution and automatic attrition require a certain amount of investment. However, now the company knows how to calculate the big account. "I can't afford the security problem. In recent years, I have been under great pressure and my hair has turned white. Now the company's underground drainage, ventilation and filling are all automatically controlled, and some posts are unattended. With the support of science and technology, there is no need to send so many employees to high-risk positions, which is a lot of peace of mind. " Wang Youyuan, general manager of Hubei Sanxin Gold & Copper Co., Ltd. told the reporter that the company now needs to withdraw 10 yuan per ton of ore as a safety fee. "The normal operation of the enterprise has a profit of about 6.5438+0 million yuan a day, and there are many peak periods. If safety is not done well, stopping production will delay efficiency. This is the biggest cost, and the vision is still long-term. "
Establishing archives of major hazard sources in mines based on big data
For non-coal mines, major hazards mainly exist in tailings ponds, dump sites, high and steep slopes and mined-out areas. What they have in common is large volume, many risk points and complicated inducing factors. When safety supervisors go to mines to check potential safety hazards, they often feel "blind people touch the elephant". How to build a more efficient risk management and hidden danger investigation mechanism?
The Institute of Safety Science and Technology of Sichuan Provincial Administration of Work Safety will make overall use of high-scoring satellites, photogrammetry, three-dimensional lasers, underground geophysical exploration and other technologies to establish health records of major mine hazards based on space, surface and underground big data, form an early warning mechanism for hazards, and improve the foundation of major accident prevention and control system. "A few years ago, we conducted a risk analysis on the planning of the proposed farmer's market in Yanbian County, Panzhihua City, and found that this location is just downstream of a tailings pond. The analysis believes that once the tailings dam breaks, the whole farmer's market will be flooded. The preventive measures we proposed were adopted, avoiding major hidden dangers and risks caused by unreasonable planning and site selection. " Examples of technical experts from Sichuan Institute of Safety Science and Technology.
Based on big data, there is also "smart electricity". Abnormal electric leakage, current overload, abnormal temperature ...... "Smart Power Use" collects and uploads real-time operation data of electrical lines through intelligent sensing terminals, which can timely find these electrical fire hazards and push the information to users; The management platform provides the government supervision department with the risk assessment report of electrical fire hazards; Then, through the development of offline professional governance comprehensive services, the hidden dangers of governance are investigated. "This has formed an effective closed loop of electrical fire hazards from discovery, supervision to governance. In 20 16, nearly 20,000 sets of' smart electricity' equipment were installed in Zhejiang province, and 20,252 hidden dangers were found, including 994 key hidden dangers, and the incidence of electrical fires dropped significantly. " Zhengping Fang, chairman of Hangzhou Jiahe IOT Technology Co., Ltd. said.
The emergency management platform promotes the effective implementation of corporate responsibility.
Safety production enterprises bear the main responsibility, but it is also inseparable from government supervision. "Some local regulatory authorities think that it will be okay to send a rectification notice, but it will be nothing if it is not urged to implement it." A safety supervisor in a western province said this. How to achieve strict supervision and make the main responsibility of enterprises "difficult to implement"?
Yubei District, Chongqing promotes the informatization of safety production, builds an emergency management platform and adds a hidden danger management module. According to the difficulty and time span of hidden dangers rectification, the hidden dangers are divided into red, orange and Huang San. The red problem is "daily cleaning and weekly progress", the orange problem is "weekly cleaning and monthly progress" and the yellow problem is "monthly cleaning and quarterly progress". Zhao Bing, director of the Safety Supervision Bureau of Yubei District, introduced that through the monitoring and analysis of platform data, hidden dangers of various units were reported regularly every month, which forced the problem to be solved. In 20 16, 8,820 hidden dangers were investigated and 8,694 were rectified in Yubei district, with a rectification rate of 98.6%.
"Accident is the biggest cost, and safety is the biggest benefit. Vigorously promoting scientific and technological progress in safety production and improving the level of safety and security are powerful barriers to prevent accidents. " He Guo said.
Looking forward to the development of science and technology for the benefit of the people.
