I get what you're saying, but the regulations were put in place to protect the miners. I think the level of anal-retentiveness of the inspectors should be examined!
Devil's Advocate:
You own a manufacturing company that operates machinery and kids are necessary to climb inside to clean, etc. It's a dangerous job and many are injured and sometimes killed. It's your property and you can do what you want without regulation and oversight?
Do you want your kid working there when you aren't sure if the owners have safety in mind?
