History
The 1907 Engineering index annual lists this colliery as the deepest bituminous coal mine in the US, a three foot vein worked longwall fashion.

A 1907 issue of the Journal of the Iron and Steel institute gives a more detailed summary and hints at the ultimate cause of its failure:

CM Young states that the deep colliery being worked at Atchison Kansas is deeper than any other bituminous coal mine in the United States At a depth of 1126 feet a bed of coal 3 feet in thickness and of excellent quality was found In order to settle the question as to the existence of coal at a greater depth drilling was carried on until the Mississippian limestones had been reached and penetrated to a depth of 38 feet Three beds of coal were penetrated below this 3 foot bed but they are not of sufficient thickness to make working profitable under existing conditions At present the mine is operated through one three compartment shaft Two compartments of the shaft are used for hoisting and downcast and the third constitutes the upcast and pipeway The coal is taken out by the long wall method which is probably the only method adapted to the conditions The mine is very wet about 1200 gallons of water being taken out per hour The present output is about 170 tons per day An analysis of the coal is as follows Fixed carbon 46 53 volatile and combustible matter 43 29 ash 6 04 moisture 3 13 total sulphur 2 27 volatile sulphur 1 17 per cent
