In a place in Shanxi Province, there are more than 140 coal mining enterprise operators, and each coal mine has an explosive depot. According to investigations and statistics, the current coal mine door locks basically use mechanical traditional door locks and keys. In fact, the seemingly solid door locks actually have a great potential risk, because if some illegal elements learn about the location of the explosive depot , You can copy the key, open the door lock or even use the advanced “master key” for technical unlocking, so that you can sneak into the explosive storehouse. Once the explosive is stolen, it is likely to be used illegally, such as: illegal mining, terrorist operations, kidnapping, etc., It may cause casualties to workers and innocent people. However, for coal mining enterprises, the biggest problem is the inability to control and supervise when personnel enter and exit the explosive storage. As a result, explosives are stolen and cause major economic losses in coal mines or cause coal mines to reduce or suspend production, and even cause irreversible major problems to the society. harm. Moreover, once a theft occurs, it is difficult for the public security department and coal mine management personnel to find out who has entered and left the explosive warehouse.
AXIS Intelligent Security Technology (Shenzhen) Co., Ltd. has more than ten years of experience in security access control solutions for many countries around the world. After in-depth research on Shanxi Coal Mine Explosive Depot, relevant technical personnel of the company provide the following security access control solutions , Can effectively relieve the potential risks and management problems faced by coal mine explosive depots.
According to survey statistics, most coal mines in China currently have an explosive depot, and these explosive depot door locks basically use mechanical traditional door locks and keys. The seemingly strong door lock actually has a great potential risk, because if an illegal element knows the location of the explosives library, he can copy the key, pry the door lock and even use a high-level “master key” for technical unlocking. Can sneak into the explosive depot.
Once explosives are stolen, they are likely to be used illegally, such as illegal mining, terrorism, kidnapping, etc., which may cause casualties to workers and innocent people. However, for coal mining enterprises, the biggest problem is the inability to control and supervise the entry and exit of explosives depots, resulting in explosive thefts and major economic losses in coal mines, or causing coal mines to reduce or stop production, and even cause irreversible major harm to society. Moreover, once a theft occurs, it is difficult for the public security department and coal mine management personnel to find out who has entered and left the explosive warehouse. Aiming at a coal mine explosive depot in Shanxi Province, the relevant technical personnel of Acsis Company conducted in-depth research and provided the following safe and intelligent door lock solutions, which can effectively eliminate the potential risks and management problems faced by the coal mine explosive depot.
Project requirements
To take safety precautions to prevent theft, you must first have a safe and reliable lock. Its security can be measured from the following aspects:
Ability to resist destruction
The most important thing for the safety of the lock is to prevent violent damage such as deliberate prying, smashing, and drilling. In this regard, the mechanical strength of current mechanical locks and ordinary electronic door locks can generally meet this requirement. Among all types of door locks, only intelligent electronic mechanical locks have a fully enclosed structure, and software controls the authority and access time of the key, which has the best security.
Prevent technology unlock
The ability of mechanical locks to prevent unlocking is very poor. No matter what kind of structure, almost all mechanical locks can be opened by its means. The AXIS smart electronic lock discards the traditional spring pin cylinder and adopts a special encryption lock cylinder, which can effectively prevent technical unlocking.
Prevent key duplication
Key duplication is the biggest security hazard. General users may often accidentally lose their keys, stolen keys, or secretly duplicate keys. If the key is stolen or accidentally lost, the general user will change the lock as soon as possible for safety. This will cause a lot of trouble and waste manpower and material resources. However, if the key is secretly copied by illegal elements, they may sneak into the warehouse and steal it. Explosives pose a huge threat to public order, and if it causes casualties to innocent people, the consequences will be disastrous. At present, traditional mechanical lock keys can basically be copied. In electronic door locks, magnetic cards are extremely easy to be copied because they have no password restrictions. At present, relatively safe IC cards and RFID cards are also threatened by cracking. According to the “Notice on Doing a Good Job in Responding to Serious Security Vulnerabilities in Some IC Cards” issued by the Ministry of Industry and Information Technology, the security technology of the M1 chip applied to the IC card system has been cracked. At present, there are about 140 million in 170 cities across the country. All IC cards that apply this technology are facing security risks.
In addition, while being safe and reliable, the stability of the door lock is also very important. Users who use traditional mechanical locks may have the experience that they cannot open the door when the door should be opened, and cannot close the door when the door should be closed, which will cause a lot of trouble. Generally speaking, among several electronic door locks, the stability of smart electronic mechanical locks is significantly higher than that of other electronic door locks. Magnetic cards are afraid of strong magnetic fields, and IC cards are afraid of oil, dust, and static electricity. The wireless intelligent electronic mechanical lock is fully enclosed, waterproof, anti-static, and anti-dust. From the perspective of the unlocking method, the key can be inserted into the lock cylinder, and after the verification and identification of the key authority by the lock cylinder, the door lock is powered by the key battery, no wiring, no power supply installation, stable use, long service life, convenient and fast, etc. Features. Because coal mines are dusty, traditional mechanical locks or padlocks are used. The keyholes or springs are often blocked by dust and cannot be opened after a long time of use. The European standard lock cylinder is used by Axais. The door lock has a large key hole. Compared with the traditional spring lock cylinder, even if there is a lot of dust, it only needs to be cleaned regularly and easily.
Design
To do a good job in the management and supervision of explosives warehouse personnel, it is necessary to have an effective security access control solution: the coal mine can set permissions for the keys of personnel entering and exiting the warehouse, and can modify or cancel the key permissions as needed at any time to prevent unauthorized personnel from entering explosives Library. In case the key is stolen or accidentally lost, you can delete the lost key or the stolen key authority in the management software, so the explosive warehouse does not need to change the lock frequently, which saves cost and time.
The coal mine manages warehouse keys and personnel entering and exiting. The managers can authorize the keys and locks in various forms for different time periods, different personnel, and different places. For example: Set the permission of “Zhang San” as the permission to pass through door 1 multiple times, the validity period is one month, and the effective daily use time is 8:00-18:00. Therefore, “Zhang San” can use the key multiple times within the valid time range. If the valid time is exceeded, the key cannot be used, and the key must be updated once a day before the first use. The update method is very simple, just insert the key into the encoder , You can automatically update the permissions and continue to use it. This can prevent outsiders from sneaking in illegally, as well as preventing insiders from copying keys or sneaking in at night to ensure the safety of explosives storage.
Coal mine managers can modify the entry and exit time of personnel in the software system at any time as needed, and can also clearly query when the warehouse door lock is opened by whom and when it is locked, and can download or print the door lock opening log at any time.
For unauthorized keys trying to open the door lock, an alarm can be issued. In this way, the copied illegal key, or the advanced “master key”, as long as it touches the lock cylinder, the lock cylinder recognizes the key. After the verification fails, the system can record it. If the key is updated in the encoder, the system can email Or a text message prompts to send out an alarm message.
System flow

Figure 1 is a schematic diagram of an intelligent electronic mechanical lock and its supporting solutions. The coal mine manager creates a key in the software system, and the access rights can be set to 15 minutes, 30 minutes, 1 hour, and 1 day. The key is handed over to the administrator of the explosive depot; if someone needs to enter the coal mine temporarily, the coal mine manager can set one If the key of temporary single permission exceeds the set time, the permission of the key will automatically become invalid.
When the coal mine manager creates the key access authority, the software system can generate a standard format prompt, and the report is sent directly to the mailbox of the relevant staff of the public security department. The coal mine manager gives the key to the miner who needs to enter and exit the explosive warehouse. When the miner uses his key to enter the explosive warehouse, his visit will be automatically recorded by the system, which can show when the door is opened and when the door is locked. For example: July 31st, a certain coal mine access information: someone 14:15-14:50.
After the miner returns with the explosives, the access record in the key can be automatically uploaded to the management software, and this record will be transmitted to the coal mine manager and the public security department in the form of a report.
Concluding remarks
This smart lock solution for the entrance and exit safety of explosives depots in coal mines can effectively manage the entrance and exit control of explosive depots, and understand and reflect the status of electronic keys and electronic locks, lock status, personnel who open the door and other information in real time. Of course, the current coal mine needs will consider the linkage issues with higher-level departments and public security departments. Intelligent, diversified, and integrated systems are the mainstream of the current security industry and the direction of research for access control companies.
