(Coal) Mine Security Defense

On the evening of March January 29, I read the coal mine information and the security status evaluation report. There are a lot of content, 50 pages of paper. I wanted to finish writing it in one breath and make up for it tonight.

The risk factor of underground mining is relatively greater than that of open-air mining, and there are more security construction prevention problems.

With the development of automation and information technology, enterprises with wings fly faster and fly higher.

(Yesterday, I talked to a friend about a coal mine. He worked in a coal mine and talked about it for one night. One of the words he often said was "Dizzy" and "your thoughts are too naive ")

After reading the conversation last night, I am adding some content today. Let's sum up my thoughts on the big questions. (Word and trustworthiness)

A coal mine is a fundamental task in production, and safety is a basic guarantee. Put security first, and discard "not afraid of sacrifice, not afraid of bloodshed" (there are many Chinese people, it will be your turn that day, over ).

Evaluation basis of coal mine security status quo: labor Law of the People's Republic of China, Safety Production Law of the People's Republic of China, Mine Safety Law of the People's Republic of China, coal mine safety regulations, coal mine safety supervision regulations, general principles of security evaluation, and coal mine safety evaluation guidelines, other laws and regulations applicable to security evaluation, security standards, technical standards, security rules, security regulations, and the document requirements of the State coal mine security supervision bureau and the provincial coal mine security supervision bureau. For example, the coal mine water control work regulations, mine ventilation safety equipment standards, the People's Republic of China mine safety law implementation regulations, and the coal and gas outburst prevention rules.

The main instruments of coal mines are as follows: main Ventilator, Local Fan, drainage pump, drainage equipment, winch lifting equipment, belt conveyor, gas drainage system (Optical Gas measuring instrument, portable methane measuring instrument, CO measuring instrument, oxygen measuring instrument, self-rescue device, harmful gas tester) locks power-off devices and underground fixed high-voltage cables.

Main systems: production system, mining system, ventilation system, gas, coal dust explosion prevention and control system, coal and gas outburst prevention and control system, fire suppression system, water control system, monitoring system, blasting equipment storage and transportation system transportation and lifting systems, air pressure and its transmission systems, electrical systems, ambulance systems, security management systems, health and health care and health monitoring systems. I will add several more seismic defense systems and information control systems.

(Using the above system, we will discuss it with automation and informatization)

1. Production System: the fundamental system, with emphasis on safety production systems. (Omitted)

2. Mining System

The mine must have at least two independent security exits that can walk directly to the ground. Real-time Monitoring of egress and trunk roads and timed understanding of branches are required.

3. Ventilation System

An Intelligent ventilation system is required to achieve real-time monitoring and notification of Air Quality in the underground, and to provide a device for timely extraction of toxic gases from the Branch section, and intelligent and selective gas supply for the ventilator. Real-time Control Quality Assurance, long-term underground operations will not be harmful to the body.

4. gas and coal dust Explosion Prevention and Control System

The fixed Smart terminal Monitoring Instrument tracks the air quality in real time and works with the ventilation system to adjust the underground environment to eliminate non-safety problems caused by air quality and composition.

5. coal and gas outburst prevention and control system

The workers carry portable Smart terminal monitoring instruments and underground positioning devices, and send data to the Information and Communication Server in real time to monitor whether the jobs within the scope of the workers are dangerous.

6. Fire Suppression System

Deploy the fire prevention facilities of the main road, including smart terminal monitoring equipment, Smart terminal fire extinguishing equipment, and isolation zone. Requirements: automatic detection, server-side command, and manual operation to enable fire extinguishing devices. At the intersection of the main hegan Road, there should be well-configured isolation areas with wall-mounted equipment. Workers must have a certain degree of self-help consciousness and carry certain survival devices.

7. Water Control System

First, do a good job of detection to avoid water hazards;

Second, we should do a good job of defense and deploy Smart terminal monitoring equipment, Smart terminal pumping equipment, and isolation tape.

Third, enable server-side command and manual operation.

4. Prepare rescue items for each road section.

8. Monitoring System

(Omitted) In my opinion, this system disappears and is no longer necessary. The information control system is replaced.

9. blasting equipment storage and transportation system

Record the items and personnel at the warehouse receiving and entrance; locate the blasting items during underground transportation. Once dangerous conditions occur during transportation, determine the road section and make a rescue plan; real-time Monitoring of the surrounding road sections to be cracked in real time. Once there is any danger, the personnel of the road section are immediately notified to take timely measures (the running of the road and the stopping of the road section ).

10. Transportation and Lifting System

Real-time Monitoring and Data feedback, fault defense system, and smart elimination of dangerous situations; leave a first-hand escape plan for link time.

11. Air Pressure and Its Transmission System

You have enough solutions to achieve real-time monitoring and data feedback. Update the devices. The new devices are equipped with automatic diagnostic devices and timed diagnostics to ensure security.

12. Electrical System

Key. Prepare a two-way solution to achieve continuous electricity. Even if production is not guaranteed, the Information Control System on the ground should maintain data exchange with the underground systems, so as to achieve real-time control and command scheduling.

13. Ambulance System

Positioning personnel underground location, wireless communication, limited self-help facilities, wall mounted rescue equipment, and forecasting rescue team. Unified Information Control System Command.

14. Security Management System

Manage personnel information, simulate training and prevent acting regularly. It is unnecessary for other systems to replace it, mainly information control systems.

15. Health and health care systems

It is not guaranteed later. Tip: strive to improve the underground environment (natural and psychological environment) and prevent various diseases (physical and psychological.

16. Earthquake Prevention System

Earthquakes are a hot topic that must be considered. The above-ground earthquake forecasting system and the preparation of underground bunker (long-time survival) should be implemented. prior to the occurrence of the earthquake, the ground personnel should be notified in time, and personnel should be able to flee to the underground bunker in time, waiting for ground rescue.

17. Information Control System

Control Centers of all systems. Able to process all data sent from other systems, and make solutions in a timely manner based on symptom patterns (average) and expert analysis (special. Can contact all job employees in real time to maintain communication and positioning with them. It can control the operation of all instruments and monitor the running status of some instruments. Manages personnel and items in and out of the warehouse.

To sum up, a people-oriented, human-based terminal, real-time communication between people, timely response to road conditions, real-time health of air quality, and timely implementation of escape routes and rescue of underground Positioning System system.
