Actually, it is possible to transplant lung, but sure, this is not solution of real problem, people for some reason cannot fulfill safety considerations.
In reality, what I seen myself, in such cases, all adequate people work with respirator or gas mask, they are now extremely affordable.
And yes, I many times hear, they feel discomfort, it is usually really hot in coal mine, so people frequently take off mask, and for short moment of slight comfort, sacrifice their health.
Unfortunately, after covid I understand them. Yes, psychology don't like wear mask, even when it is not really limiting breath.
I few times have to just sit in mask for 2-4 hours, this was extremely hard.

In New Jersey which also has lots of stone cutting, doesn’t allow dry cutting and has entirely different advice.

> New Jersey law (N.J.S.A. 34:5-182) requires that employers provide workers with full-face air-purifying respirators when engineering controls cannot be used. Use of respirators should be part of a complete respiratory protection program.
While the CA page says
Respirators should only be used:
• As a last resort for
protection when local
exhaust ventilation or
water controls are not
feasible or do not
adequately control
employee airborne
exposures.
• Where exposures
exceed the permissible
exposure limit (50 μg/m3,
8-hour TWA) while installing or implementing feasible
engineering and work practice controls.
• When the employee is in a regulated area.
I.e., both say that other measures must be applied first.
