Recently, the hunan department of emergency management issued a circular on further strengthening the safe management of electrical and electrical equipment in underground mines, which effectively curbs accidents in the transport of mechanical and electrical minerals in underground mining enterprises and makes seven-pronged normative requirements to ensure the safety of their production。
I. Institutionalizing the security management of electrical and mechanical facilities
The principal managers of underground mines shall, in accordance with their statutory responsibilities, organize a comprehensive overhaul of the management system (procurement, installation, operation, maintenance, end-of-life) for electrical and electrical equipment, including: procurement of electrical and electronic equipment, pre-entry inspection, installation and acceptance, inspection and repair, testing, management of the training of special equipment operators, mandatory end-of-life of mechanical and electrical equipment; and the development of safety operating protocols, safety job responsibilities and standards for the management of electrical and electrical equipment of all types, maintenance personnel, operators and appraisals, as well as the organization of training for relevant practitioners in the management and operation of electrical and mechanical equipment, duties and processes for the management and management of solid equipment, and strict protection against leakages in the management of electrical and mechanical equipment. (coalmine safety protocol 4. 2, 4. 4, 4. 5, 4. 6, metal non-metallic mines safety protocol 4. 1. 2, 4. 1. 5, 4. 5. 1)
If the principal official fails to fulfil his or her responsibility for the management of safe production, he or she is ordered, in accordance with article 94 of the law on safety of production, to correct the deadline by imposing a fine of between $20,000 and $50,000, and if the delay is not corrected, a fine of between $50,000 and $100,000, and to suspend and rehabilitate the production establishment。
Specializing in the operation of mechanical and electrical facilities
Each independent production system in an underground mine shall be equipped with mechanical and electrical masters with a degree of higher education or technical qualifications of the same type as a secondary and higher technical qualification, technical staff with a degree of secondary education or technical qualifications of the same type; masters of mechanical and electrical technology shall possess and be certified as having competence in safe production and management. Personnel working on the installation, commissioning, inspection, maintenance and troubleshooting of mechanical and electrical equipment under wells, personnel operating the upgrade equipment for transport of personnel, ores, quarries and materials, personnel operating the coal mine mining machine (drilling machine), personnel operating the coal mine gas pump, and other special operations personnel must have the corresponding special operating qualifications to be on board; electric vehicles, shovels, drillers, anchors, mechanical broken-down cars, scavengers, scavengers, and non-track transport vehicles must have a motor vehicle driver's certificate (b1 and above) and must be trained by the mine company to operate the vehicle in a non-trajectorized vehicle. (coalmine safety protocol 9. 2, metal non-metallic mines safety protocol 4. 3. 1, 4. 1. 3, 4. 5. 1)
In the event that the director of the machine or electric power plant, the mechanics and mechanics and the special operators of the non-metal non-metal underground mining enterprise are not trained and qualified for specialized safety operations and are placed on duty in accordance with the provisions of article 97, paragraph 7, of the law on safe production, the penalty shall be a fine of up to $100,000; in the case of delay in the correction, the suspension of the operation shall be ordered and a fine of up to $100,000 and a fine of up to $250,000 shall be imposed on the person in charge and other persons directly responsible。
Iii. Safety signs for access to electrical and mechanical facilities
Strictly in accordance with the circular of the national mine safety inspectorate on the publication of a catalogue of mineral products administered with safety marks (2022] (123) requires the use of products with mineral-based safety signs for equipment that is included in the management of mine safety signs. The principals of the mines shall organize a comprehensive screening of the facilities of mechanical and electrical equipment in use, and shall not enter the wells if the equipment facilities covered by the security signs of the mines do not obtain the safety signs of the mineral products. The use of equipment and processes that endanger the safety of production that should be phased out is prohibited. The blast-proof electrical equipment should be subject to blast-proof inspection and a certificate of access to the well should be issued. (coalmine safety protocol 10. 1, 10. 4, 448, metal non-metallic mines safety protocol 4. 1. 7, 4. 7. 5)
Equipment facilities under mines that do not obtain safety marks for minerals (2022] article 99, paragraphs 6 and 7, of the safety of production act imposes a fine of not more than $50,000 and not more than $200,000 on persons who use equipment, materials or processes that are prohibited by state order. If they are overdue, the penalty shall be a fine of not less than $50,000 and not more than $200,000 on the person directly responsible and on the other persons directly responsible。
Periodicization of testing of mechanical and electrical equipment facilities
Strict implementation of the metal non-metallic mines safety protocol, coal mine safety protocol, is regularly tested by professionally qualified inspection agencies for vital equipment related to personal safety, such as main ventilation systems in use, main drainage systems, air compressors, lifting of winch systems, anti-aggressors, ramps and main liftings, unorbited transporters, lifting of steel cords, pit cantons and connectors, mine lifts, empty man-loading devices, belt-carrying and radio resistance. The head of mechanical and electrical equipment in the mine is required to use security clearances for the electrical and mechanical installations and to conduct a quarterly security check of the mechanical and electrical installations for the upgrade, transport, ventilation, drainage and distribution systems. Equipment facilities meeting the end-of-life standards should be replaced immediately and problems identified should be addressed immediately; test reports, replacement records and disposal results should be recorded and archived in a timely manner. Inspection agencies should conduct tests of electromechanical equipment in strict compliance with inspection norms, prohibit missing items, alter data and issue false reports. (coalmine safety protocol 37, 158. 7, 314, 374, 383. 9, 410, 411, 416, 429, 483, metal non-metallic mines safety protocol 4. 7. 51. 2, 4. 5. 1)
Failure to carry out regular inspections of facilities of vital equipment in connection with physical security is punishable by a fine of up to $50,000 under article 99, paragraph 3, of the safe production act, and by a fine of between $50,000 and $200,000 for those who have not yet done so, as well as a fine of between $10,000 and $20,000 for those who are directly responsible and others who are directly responsible; and, in serious cases, a fine of less than $10,000 and less than $20,000 for the suspension of work。
V. Account of material and equipment facilities maintenance and maintenance posts
Underground mines shall establish a full life cycle archive management process for critical equipment such as “procurement, installation, use, maintenance, repair, inspection, end-of-life” and record the records of electrical equipment, starting with the acquisition of equipment, recording the name of the equipment, specifications, date of purchase and price, manufacturer, technical parameters, mine marking, product certification, maintenance of product usage statements, installation and debugging, pre-entry inspection, periodic maintenance and inspection. Equipment, facility periodic inspections and maintenance systems are to be strictly enforced, equipment is to be inspected, tested, repaired, maintained and maintained in a timely manner, and detailed records of inspection, testing, repair, maintenance and maintenance content, time, are to be confirmed and archived by the co-signing of the maintenance staff and equipment managers to improve the efficiency and security of the equipment. (coalmine safety protocol 4, metal non-metallic mines safety protocol 4. 7. 4)
If no regular maintenance, maintenance or management information and records are available for critical equipment facilities, the penalty shall be a fine of up to $50,000, in accordance with article 99, paragraph 3, of the law on safe production, and if the delay is not corrected, the penalty shall be a fine of between $50,000 and $200,000 and a fine of between $10,000 and $20,000 for the person in charge directly and other persons directly responsible, and, in serious cases, a fine of between $10,000 and $20,000。
Vi. Routine check of placarding of mechanical and electrical equipment facilities
Underground mines are to be constructed in conjunction with a dual preventive mechanism, organizing annual risk identification and special identification of electrical and mechanical equipment, conducting a comprehensive screening and identification of safety risks in the use of electrical and mechanical equipment, identifying control measures for the various types of equipment, graded responsible persons, developing risk plate boards for electrical and electrical equipment, hanging in the vicinity of mechanical and electrical equipment (or concentration areas), conducting shift confirmations, day check confirmations, weekly check-ups confirmations to ensure that the equipment is operated without disease。
If no security risk classification system has been established or no corresponding control measures have been taken in accordance with the security risk classification, article 101, paragraph 4, of the law on safe production provides for a penalty of up to $100,000 for correction and, if it has not been corrected, a fine of between $100,000 and $200,000 for suspension and a fine of between $20,000 and $50,000 for the supervisor and other persons directly responsible
Vii. Early warning of security risks to electrical and mechanical facilities
Underground mines use new applications of new internet technologies, such as upgrading, transportation, power supply, drainage, air-voltage machines, major ventilators, hydrogeological mains, electrical equipment, etc., to adapt all aspects, angles, and chains, to develop action plans for essential security upgrades and to achieve the full coverage of critical equipment sensor data collection, analysis and sound warning. By the end of 2024, a fixed-duty unmanned and alarm system, such as a central pump house, a power station and a main wind pump, will have been fully established. On-line monitoring of early warning systems is to be established with wire ropes and lift machines; in accordance with the “video-free” requirement, there is a timely warning of unsafe behaviour by underground workers at points of entry and exit of personnel, such as wellhead signal rooms, uplifting rooms, boreholes, pony doors (truck yards) and stop points for electric cars and specialized equipment under wells. The major equipment control system and the ai video monitoring centre are to be established at the mine command centre to send sound warning messages and on duty personnel are to notify evacuations through the broadcast system at the first time。
The installation, use, testing, modification and end-of-life of safety equipment does not meet national or industry standards and, in accordance with article 99, paragraph 2, of the law on safe production, a fine of up to $50,000 shall be imposed on the installation, use, testing, modification and end-of-life of safety equipment, and, in cases of delay, a fine of between $50,000 and $200,000 shall be imposed on the person directly responsible and other persons directly responsible, and, in serious cases, a fine of between $10,000 and $20,000 shall be imposed on the person in charge and the person directly responsible。
