The situation of mine safety production remains grim and complex

Since the beginning of this year, the situation of mine safety in China has been generally stable. From January to February, there were 25 mining accidents and 40 deaths, down 46.8 percent and 43.7 percent, respectively, according to the Ministry of Emergency Management.

"However, the situation in mine production safety is still grim and complex, facing risks and challenges brought by continued high prices of mineral products, relatively concentrated resumption of work and production, increasingly serious major disasters, and tight continuation of mining and excavation." Zhang Xin, deputy director of the National Mine Safety Administration, said that the recent series of accidents in Guizhou, Yunnan and other places have exposed that some regions and enterprises do not have a strong concept of safety development, weak awareness of the rule of law, repeated violations of laws and regulations, the implementation of the main responsibility of enterprises is not in place, the safety foundation is weak, and the supervision and supervision capacity is insufficient. In this regard, the State Administration of Mine Safety Supervision requires that all levels of mine safety supervision and supervision departments should comprehensively use interview exposure, accountability, execution convergence, joint punishment and other means to punish and form a strong deterrent for all types of violations found.

Accelerate the promotion of "Internet plus regulation"

Since 2016, the number of underground coal mine operators in the country has decreased by a total of 370,000 people, the number of intelligent mining faces in the country has reached 813, and the intelligent violation control system has been applied in many coal mines. These cannot be separated from the national mine safety supervision department in recent years to accelerate the advancement of mine safety science and technology and the construction of intelligent information technology in coal mines.

According to Wang Duanwu, director of the Science and Technology Department of the National Mine Safety Administration, in order to continue to improve the level of mine safety security, the National mine Safety Administration adheres to the four aspects of "management, equipment, quality and system" and deeply promotes the construction of a standardized management system for coal mine safety production.

In terms of information construction, vigorously promote the construction of coal mine safety risk monitoring and early warning system, and all 2,611 coal mines under normal production and construction in the country are connected to the Internet, achieving full coverage of coal mine safety risk monitoring and perception data "a network"; The coal mine safety supervision and supervision business system has realized cross-level, whole-process and collaborative integration of law enforcement business applications. Last year, the whole system used the business system to produce more than 61,000 law enforcement documents, carried out more than 12,800 law enforcement activities, and the law enforcement informatization rate reached 100%. In addition, docking and sharing with the national integrated government service platform, 2,699 government service matters will be handled in 2021, and government services will be handled in one network.

According to reports, in order to accelerate the practical application of "Internet + supervision" in the field of mine safety, the construction of "electronic seals" in coal mines and the monitoring and analysis of electricity consumption index are currently being promoted to provide technical support for strictly preventing illegal and illegal organization production behaviors. In order to accelerate the application of information systems, a "daily report, weekly notification and monthly supervision" mechanism has been established for risk analysis and research. The number of national gas over-limit alarm records dropped from 1,632 in a single week to 199, and the number of over-limit alarms decreased significantly, providing a strong information support for preventing and resolving major risks in coal mines.

In addition, the Ministry of Emergency Management and the State Administration of Mine Safety have also made new progress and breakthroughs in promoting the intelligent construction of mines.

"At present, the number of intelligent mining faces in China has reached 813, an increase of 65 percent compared with 2020, and 29 kinds of coal mining robots have been applied in more than 370 mine sites." Sun Qingguo, director of the safety foundation Department of the State Administration of Mine Safety, said that there are 146 unmanned vehicles in open-pit coal mines, and the intelligent violation control system has been applied in many coal mines.

Special rectification began to tackle the root causes

"Since the three-year special rectification campaign for mine safety was launched in 2020, the special rectification of mine safety has achieved good results through the investigation and rectification in the first two years and the concentrated attack." Zhao Yuhui, deputy director of the comprehensive Department of the State Administration of Mine Safety, said.
