Once upon a time…
Before and after workers went underground, they would do headcounts to if know everyone came out. They would also rely on the social aspect of the workers to know who was still underground that day. Mining was not a safe job.
After the booming Gold rushes in California, BC and Ontario, workers started to band together and form unions. Companies and governments started to band together and form associations. All of this resulted in mass changes across the industry, improving things like safety, pay and working conditions.
One of the most important improvements to worker safety was the brass board. A brass board was a safety tool that represented how many workers and whom was underground.
Miners used the brass board. They would take a piece of brass off the board and put it in their pocket. This left a hole on the board, which meant someone was underground. It also had a unique number, which allowed them to identify the person if something bad ever happened to them.
This became a standard practice in the industry. Unions, corporations and industry associations all liked it. Then in the 1960s, the government regulators made it mandatory for all mines. This spread across the world and is now regulation in almost every country with an operating mine.
Corporate culture and employee morale became a thing for success. Someone realized that the piece of brass that every worker keeps in their pocket symbolizes their chance of dying on the job.
Management decided to modify the brass board into a tag board. Instead of workers removing a brass and putting it in their pocket, they would instead place a card on the board with their name on it.
An un-intended consequence…
Now that workers didn’t have a piece of brass in the pockets, they didn’t feel the weight reminding them to tag out of the mine. Workers began to forget their tags on the board. But this didn’t matter because in the 1970s, mining had one of the biggest bull-runs in history. Gold went from $35/oz to $900/oz.
There was a flat market from 1980 to 1999, where commodities stayed relatively stable and profitable. But then from 1999-2011, the mining industry had another massive run in commodity prices, sending Gold from $250/oz to $1,900/oz.
Everyone in the industry wanted to cash in on this trend. From the workers underground to the executives in the boardroom, everyone wanted to maximize their bonuses. So, no one cared about optimizing efficiency. They only cared about maximizing production.
From 2008-2011, most of the industry went after the high-grade areas of their mines to produce the most amount of ore in the shortest time frame. This left lower-grades from 2011 onward and then prices started to decline… a lot.
Responding to the profitability crunch...
Management started cutting expenses. First, the unnecessary expenses like jets and parties went. Then, the high-priced consultants and contractors. Finally, they started doing large layoffs of their workforce. This had a bad effect on morale and on company culture.
The industry took a long time to get there, but they finally looked at improving operational efficiency. As a part of that, companies are turning to innovation and in particular digitization.
One common goal of underground mining companies is eliminating unexpected production setbacks. In particular, unplanned delays to the blast schedule can cause production gaps that are hard to make up. For many mines, a simple human error is still causing production delays that cost their mines more money than they realize.
When a worker forgets to remove their tag from the tag board at the end of the day, the safety team can't give the all-clear to the blasting team. In a worst-case scenario the miner that forgot their tag is already on their way home, and it costs the mine 1-2 hours of production while they track them down.
An Innovative Solution
By creating a digital "back-up" of the brass board (aka Tag Board) mines can remind their crews to tag-out before leaving the mine. The board can be integrated with mine security to all-out prevent a miner from leaving the operation if they are still tagged-in underground. In addition to preventing blast delays, a Smart Tagboard can also:
- Ensure that anyone in the mine can see the current state of the brass board from any computer.
- Reduce confusion during emergencies by quickly reconciling the brass-board status with other location tracking systems.
- Get an affordable way to digitize a 100 year old safety procedure and create new metrics for your management.
