Geological Problems Reported

A 1911 gas explosion near the sealed connection to the O’Gara No. 4 Mine resulted in the suffocation of eight men. Several faults, trending northwest-southeast, cut through the northeast portion of the mine. The roof in the center part of the mine was 1.5 feet of crumbly shale that tended to come down, overlain by a good roof of hard gray shale. The western part of the mine had poorer roof conditions, with boney coal and carbonaceous shale that contained partings and horizontal slip planes. The northern and southern parts of the mine had many slip planes in the roof that made for dangerous conditions. The coal contained pyrite balls and streaks; the lower half of the coal was cleaner than the upper portion.

Sources of Data

Source Map Map Date Original Scale Digitized Scale Map Type
Microfilm, document 352793 9-1923 The legend on this source map stated that the map was prepared in September 1923 and the last extensions were surveyed January 10, 1923. However, several entries have the date “4-14-1923" inscribed on the furthest extensions, implying that this map is final or very nearly so, but this outline is not consistent with the final outline shown on the 1931 map, which shows approximately 15 additional acres. The mined area shown on the accompanying map is the approximate size expected for the production reported. This suggests that the mine outline is complete. 1:2400 1:4138 Not final
