THE ROLE OF THE MISSOURI GEOLOGICAL SURVEY IN UNDERGROUND MINING AND SPACE UTILIZATION IN KANSAS CITY, MISSOURI

The Geological Survey, which encourages the utilization of mines and underground space, recognizes the responsibility of providing basic geologic data so that mined-out space can be safely and wisely developed. Several studies have aided in the understanding of roof and surface stability in mined areas. A 1969 Geological Survey report included a discussion of the geology as well as suggestions for pillar, roof and overburden dimensions to reduce the problems of roof failure and surface collapse. Commonly used dimensions, assuming no roof bolting in the more stable mines include: roof span of 40 feet or less; pillars, 20 feet or more diameter; pillar center-to-center spacing, 60 feet or less; mine roof (back) with 5 feet or more competent limestone overburden including at least one-half, preferably all of the winter-set above the mine; removal of shale in the mine floor limited to transportation routes into the mine; and mine development so that drainage does not flow down deep into the interior of the mine. The Geological Survey also encouraged the development of underground transportation routes in the Metropolitan Kansas City area in the late 1960's. The Survey has recognized the unique setting of the Bethany Falls Limestone which is easily accessible from the surface and offers a major mineral resources and development asset to the region.
