Biometric Systems for Mining Safety: Access Control, Attendance and Worker Tracking

Safety is the most crucial aspect in the mining industry because mining is one of the most critical and dangerous jobs in the world. Explosions, poisonous gases in the underground air, accidental collapse of strata, sudden increase in underground temperature, water inrush or flooding, heavy machinery or equipment crushing, rockfalls and haulage failure are the most common types of accidents that put labour safety in mines at risk.

Hence mining companies put extra focus on assessing the sources of risk within their mines, promoting 100% compliance with safety regulations, and installing mining surveillance and biometric solutions for access control within specific zones of their mines. In this article, we shall discuss the key challenges in mining safety, the need for biometric systems in mining, and the key applications and benefits of biometrics in mining.

Quick answer: Biometric systems improve mining safety by allowing only authorised, fit-for-duty workers into hazardous zones, recording who entered which zone and when, and giving rescue teams an accurate headcount during emergencies such as gas leaks, roof falls or flooding. They also stop proxy attendance and help mines meet DGMS safety and record-keeping requirements.

​Challenges in Mining Safety

While no safety aspect should be treated as trivial, we shall throw some light on the most common challenges encountered in mining safety and security for mines.

Gas Leaks and Respiratory Hazards

Monitoring gas leakages is an essential component of mine safety. Methane, Carbon monoxide, Hydrogen sulphide, Carbon dioxide and other toxic gases in the underground air in mines pose fatal risks for employees. Most gas leakages occur either due to lack of preventive maintenance or due to human blunders. Let’s take a hypothetical scenario, where an employee who is not allowed access to a restricted area, trespasses into it and makes unauthorised changes in some equipment settings. Such an action may lead to unwarranted changes in the operations of equipment, leading to gas leaks or even more dangerous respiratory hazards. Setting up biometric access control can be an effective way to avoid such situations.

Collapsing of Mine Stopes and Strata

Due to incorrect blasting practices and other geological factors, collapse of stopes and overlying strata is a frequent phenomenon in mining operations. Biometric systems in mining can enable more stringent access control at collapse-prone and dangerous zones of the mine.

Biometric solutions focussed on mining industry safety, especially facial recognition systems, also maintain accurate records of which zone of a mine an employee last checked into, so that in case of any unprecedented situation, the missing employee can be readily tracked.

Water Inrush and Flooding

Water inrush mostly happens due to crack development, following erroneous blasting or excavation. While mining biometric solutions cannot directly prevent the occurrence of water inrush accidents, they can help rescue personnel locate victims based on their last fingerprint scan or facial recognition records in the mining surveillance system.

Accidents from Heavy Machinery and Mining Equipment

Most accidents caused from crushing by heavy mining machinery are due to either unauthorised personnel handling the equipment, or due to the effects of intoxication or drowsiness of the concerned machine operator. Advanced mining biometric solutions can detect such characteristics of employees by actively monitoring behavioral patterns, as well as integration with respiratory alcohol-level sensors.

Trolley and Haulage Accidents

Trolleys used in mining activities operate in a very narrow tolerance zone of safety, and are highly susceptible to accidents due to rope breaks, entanglement with other machinery, swinging movements due to sudden drag, human errors etc. Haul trucks used in opencast mining projects are also the harbingers of many mining accidents, due to collisions with other trucks or running over employees. Mining biometric solutions restrict access to haulage machinery and trolleys to only authorised persons, and can also detect intoxication.

Underground Temperature Hazards

Underground temperatures may abnormally increase in a mine due to multiple reasons, such as latent heat sumps, ventilation failures etc. IoT sensors, combined with video feeds from surveillance systems, can activate trigger alerts to the Safety Head of the mine, while records from mining biometric systems can be used to identify which employees are stuck in the zone of danger.

Why Biometric Systems are Crucial for the Mining Industry?

The Mining Industry in India is regulated by the Mines Act, 1952, Mine Rules – 1955, Coal Mine Regulation-2017 and other statutory provisions that the Directorate-General of Mines Safety (DGMS) legislates from time to time. Safety and welfare of employees in mines is not just a regulatory mandate but is also vital for mining enterprises from a productivity perspective. Undertaking preventive mining safety involves installation of MSA or mine safety appliances, combined with AI powered mine security systems.

This is where Mining Biometric Systems come into play. By leveraging the power of AI surveillance, combined with facial recognition, fingerprint technology, and card-based authentication, mining biometric solutions help mining enterprises achieve the highest standards of labour safety, while also securing their vital physical resources.

Key Applications and Benefits of Biometrics in Mining Industry

Mining Biometric Systems have diverse applications, and their implementation yields a plethora of benefits for the mining companies. Here we shall throw some light upon the major applications and benefits of mining biometric solutions.

Access Control

Access control is the most common, and yet the most important, application of mining biometric solutions. Access control helps to strengthen security for mines by monitoring access to critical zones in the following ways:

• Regulating entry to high-security areas (such as Mine Director’s Office, Server Room etc)

• Restricting unauthorized access to Gas and Water Control Rooms, Power Control Centre, Haulage Equipment Control Room etc.

• Authenticating access to operate heavy machinery and haulage trucks, thereby preventing equipment misuse

• Alcohol and Fatigue Monitoring of mining workers, for enhanced mine security.

Biometric Time & Attendance Management

Time frauds are very common in the mining sector and hence biometric mining solutions are intended to effectively manage attendance, clock-ins and clock-outs for employees working under the mine. The key applications of biometric mining safety systems in this field are:

• Time and attendance recording

• Automated payroll processing

• ​Transaction authentication for vendor payments

• Preventing identity spoofing by mine workers

Platforms like iDONE HRMS link biometric punches directly to shifts, leave and payroll, so contractor and shift attendance in the mine stays accurate without manual registers. For remote or open-cast sites, geo-location based attendance and palm vein recognition are useful alternatives where fingerprints wear out.

Real-time Monitoring of Mine Security

Mining biometric solutions enhance labour safety by enabling the management to conduct real-time monitoring of high-risk zones in the mine, tracking victims in case of any unfortunate incident in the mine, and sending proactive alerts for violations of safety procedures. Biometric systems have, in the past, proven to be very effective in emergency response and evacuation. The mining biometric system can be configured to send alerts to the respective team leaders whenever their team members attempt to breach into an unauthorised access section of the mine.

Biometric records work best alongside AI-powered CCTV surveillance at portals, shafts and control rooms, and tools like CheckCam alert the safety team when a camera at a critical zone goes offline or is tampered with.

Equipment Theft Prevention

Mining involves usage of very high value machinery and mining equipment in remote locations, which make these susceptible to theft. By defining perimeters for machinery parking and equipment storage, and then installing mining biometric solutions at the entry and exit points of the perimeter, mining companies can control incidents of equipment theft to near-zero levels.

1. Enrolment: each worker and contractor is enrolled once with face or fingerprint, linked to their role, training and medical fitness records.

2. Entry check at the mine portal: the worker is verified at the gate or lamp room, and entry is blocked if training, fitness or shift details do not match.

3. Zone-level access: readers at shafts, control rooms and equipment bays allow only authorised people into each zone.

4. Live headcount: the system keeps a real-time list of who is underground and in which zone.

5. Emergency response: during an incident, rescue teams get the last known location of every worker within seconds.

6. Exit and reporting: exit scans close the record, feeding attendance, payroll and DGMS compliance reports.

A typical mining biometric setup follows the worker through every shift:
