asked the Secretary for Mines what were the numbers for a year, up to the last convenient date, of fatal accidents occurring at the coal face where the coal is pick-hewn and there are no pan-runs or conveyors; where the coal is machine-cut but no pan-runs or conveyors are used; and where the coal is machine-cut and pan-runs or conveyors are in operation?

I regret that this information is not available.
