Book excerpt: This report presents the results of field inspection and evaluation of the Black Tailings Dam. This dam has been classified as unsafe, emergency by the St. Louis District as a result of the application of the following criteria: (1) This dam which has no spillway will not contain a 10-year frequency flood without overtopping occurring. The storage capacity of this dam is, therefore, considered to be unusually small and seriously inadequate; (2) Overtopping could result in dam failure; and (3) Dam failure would significantly increase the hazard to life and property downstream.

Download or read book National Dam Safety Program. Old Mines Tailings Dam (MO 30706), Mississippi - Kaskaskia - St. Louis Basin, Washington County, Missouri. Phase I Inspection Report written by Kenneth B. King and published by . This book was released on 1980 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the inspection was to assess the general condition of the dam with respect to safety. The assessment was based on an evaluation of the available data, a visual inspection, and an evaluation of the hydrology and hydraulics of the site to determine if the dam poses hazards to human life or property. The purpose of the dam is to impound tailings from a barite separation and beneficiation operation. The results of the inspection and evaluation indicated that the spillway does not meet the criteria given in the Guidelines for a dam with the size and hazard potential of Old Mines Tailings Dam. As an intermediate size dam with a high hazard potential, the Guidelines specify that the discharge capacity and/or storage capacity should be capable of safely handling the Probable Maximum Flood (PMF) without overtopping the crest. The PMF is the flood that may be expected from the most severe combination of critical meteorological and hydrologic conditions that are reasonably possible in the region.

Phase I Inspection Report written by Kenneth B. King and published by . This book was released on 1979 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of Dresser No. 4 Dam is to impound tailings from a barite separation and beneficiation operation. The dam completely encircles the impoundment except for a 300-foot wide breach at the north (up-stream) end where the structure failed in 1975. The dam cannot retain water in its present state because of this breach in the dam. This dam is classified as large. The U.S. Corps of Engineers has classified it as having a high downstream hazard potential to indicate that failure of this dam could threaten life and property. The damage zone, estimated by the U.S. Corps of Engineers, extends about 6 miles downstream of the dam. Since the embankment cannot retain water, the overtopping potential of the embankment was not analyzed. Instead, studies were made to estimate the amount of flow that could occur in the diversion ditch (located to the west and south of the impoundment) under different flood conditions. It was calculated that the diversion ditch could pass a 100-year flood probably without significant erosion of the ditch or adjacent embankment toe. However, it was estimated that the ditch cannot pass 50 percent of the Probable Maximum Flood without significant erosion of the ditch and adjacent embankment materials.

Phase I Inspection Report written by Richard G. Berggreen and published by . This book was released on 1981 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Old Viburnum Tailings Dam was constructed over a rock-fill starter dam. The main embankment was constructed of cyclone-deposited tailings, apparently maintaining a constant dam crest centerline over the starter dam. The decant system which passed water from the reservoir to the downstream toe was sealed with grout when operations on this dam ended in 1972. The embankment was covered with a thin mantle of soil, and grass was planted to control erosion. However, the vegetation has not become well established and substantial erosion gullies have developed. The most prominent gullies are along the abutments where overland runoff flows onto the tailings embankment. The spillway is about 900 ft southwest of the dam axis and consists of a cut through the ridge which forms the southeast side of the reservoir and right abutment of the dam. The excavation for the spillway extends into weathered bedrock and little or no erosion in the spillway is anticipated during flood flows. Hydraulic and hydrologic analyses including multiple dam analyses of the significant upstream dams indicate the dam will not be overtopped by 100 percent of the PMF.

Book Synopsis National Dam Safety Program. New Viburnum Tailings Dam (MO 31231), Mississippi - Kaskaskia - St. Louis Basin Iron County, Missouri. Phase I Inspection Report by : Jean-Yves Perez
Download or read book National Dam Safety Program. New Viburnum Tailings Dam (MO 31231), Mississippi - Kaskaskia - St. Louis Basin Iron County, Missouri. Phase I Inspection Report written by Jean-Yves Perez and published by . This book was released on 1981 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dam is being constructed of lead tailings on top of an earth starter dam. It impounds lead tailings. The St Louis District (SLD), Corps of Engineers, has classified this dam as having a high hazard potential. The SLD estimated damage zone length extends approximately 15 miles downstream of the dam. Within five miles downstream are several dwellings, a church, a quarry and the town of Courtois. The contents of a portion of the damage zone were verified by aerial reconnaissance. New Viburnum Tailings Dam is classified large size based on its present height of approximately 110 ft. The present storage capacity to the spillway crest is approximately 4750 ac-ft, of which approximately 4000 ac-ft is tailings. The large size dam classification includes dams higher than 100 ft, or having storage capacity greater than 50,000 ac-ft, whichever gives the larger classification. On the basis of the visual inspection, review of available data, and inspection of aerial photos, the dam is judged to be in poor condition. This judgement is based on observation of uncontrolled seepage and associated slumping at the downstream toe of the dam, the presence of a large, 20 to 30 ft diameter sinkhole on aerial photos of the dam taken in November 1980, and lack of knowledge on the remedial measures taken to repair the sinkhole. No evidence was noted of cracking, extensive erosion, deep seated slope instability, or settlement of the crest. During the field inspection in February 1981, we did not detect the presence of the sinkhole, but did observe a drain pipe flowing at the rate of about 125 gal/min, a zone of wet tailings, and uncontrolled seepage and slumping, in the area where the sinkhole existed in November 1980.

Phase I Inspection Report written by Kenneth B. King and published by . This book was released on 1979 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of No Name 587 Dam is to impound tailings from a barite separation and beneficiation operation. The dam completely encircles the impoundment. Runoff from the watershed is diverted around the impoundment via diversion ditches. This dam is classified as intermediate size. The U.S. Corps of Engineers has classified this dam as having high downstream hazard potential to indicate that failure of this dam could threaten life and property. The damage zone estimated by the U.S. Corps of Engineers extends approximately eight miles downstream of the dam. Information provided by the Corps of Engineers and the inspection indicates that about five dwellings, two railroad bridges, a highway bridge and the town of Mineral Point with about eighty dwellings are within this damage zone. The results of the inspection indicate the absence of facilities for discharging floodwater and inadequate freeboard and that the dam does not meet the criteria given in the Guidelines for a structure with the size and hazard potential of No Name 587 Dam. As an intermediate size dam with a high hazard potential, the Guidelines specify that the discharge capacity and/or storage capacity should be capable of safely handling the Probable Maximum Flood (PMF) without overtopping the crest.

Berggreen and published by . This book was released on 1981 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: The St Louis District (SLD), Corps of Engineers, has classified this dam as having a high hazard potential. The dam is classified intermediate size based on its height of about 45 to 50 feet. The downstream face is steep, on the order of 33 to 35 degrees, is constructed of cohesionless sand gravel, and could be severely eroded if overtopped. Scattered large trees up to 12 in. diameter are growing on the downstream face of the dam. The reservoir storage volume is completely filled with fine tailings and storage of water is limited to two small ponds at the upstream end of the impoundment, and shallow, intermittent ponds on the surface of the tailings. Hydraulic/hydrologic analyses indicate the dam and informal spillway will pass the 1 percent probability-of-occurrence event (100-year flood) without overtopping the embankment. These analyses further indicate the dam will be overtopped by a storm which produces greater than 55 percent of the Probable Maximum Flood (PMF). Based on the inspection of the Dam, it is recommended that further study be conducted without undue delay, under the guidance of an engineer experienced in the design and construction of tailings dams.
