Book excerpt: Prior to 1977, effect of mine subsidence was not fully considered. A lack of awareness of subsidence potential, combined with urban expansion, resulted in many homes and neighborhoods being built over these old mines. Subsidence over abandoned coal mines is a potential hazard for an estimated 25,000 people and 7,500 houses along the Front Range Urban Corridor (2004 figures).

Book excerpt: As a result of more than 200 years of underground coal mining, many urbanized areas throughout Ohio, USA, are susceptible to land subsidence. Approximately 6,000 abandoned underground mines (AUMs), with a footprint of roughly 800mi2 of undermined land, have been identified by the Ohio Department of Natural Resources Geologic Hazards Division (ODNR GHD), with further estimates of as many as 8,000 AUMs beneath Ohio's legacy coal mining region. Previously, efforts to monitor subsidence have been sparse or temporally discontinuous, leading to an incomplete understanding of how subsidence in these areas occurred. We apply a robust alternative to traditional land surveying using Persistent Scatterer (PS) radar interferometry, a refinement to traditional radar interferometry techniques. Wellston, OH, which continues to be an unstable AUM area based on subsidence damage claims, was investigated because the downtown area rests above several unstable ~100 year old room-and-pillar mines at an average depth of only 10 meters, overlain by a thin layer of unconsolidated material, a more significant unit of limestone, intermittent mudstone, and sandstone. Since 1993, 8 separate subsidence claims have been confirmed by state agencies in Wellston, which have cost more than $250,000. 18 ERS-1 and ERS-2 SAR images were acquired over Wellston, Ohio covering April 1992 and February 2000, and used to monitor subsidence over that time period. Resulting PS based displacement maps show ground movement for the town. In areas of higher numbers of damage claims at the surface, the movement is generally non-uniform. In areas with uniform ground movement, damage claims are minimal. As the time since abandonment of AUMs continues to increase, subsidence related damages are expected to increase, reinforcing the need for a predictive subsidence model. Using the georeferenced AUM maps, water well logs, and geologic information for Wellston, a multivariable GIS model was developed in order to predict areas at most risk to future subsidence hazards. Variables in the model included, (1) void space, (2) thickness of mine overburden (3) thickness of unconsolidated overburden, (4) presence or absence of pillars, and (5) proximity to mined out areas, (6) standard deviation of PS results. Results from the GIS model agree well with the current subsidence claims, and high magnitude subsidence determined via PS analysis.
Book Synopsis Overview of Mine Subsidence Insurance Programs in the United States by : David K. Ingram
Download or read book Overview of Mine Subsidence Insurance Programs in the United States written by David K. Ingram and published by . This book was released on 1993 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research performed by the U.S. insurance industry has determined that mine subsidence is uninsurable. Consequently, the insurance industry has decided not to voluntarily offer mine subsidence insurance. The U.S. Department of the Interior has long been investigating the effects of mine subsidence; these investigations have resulted in Federal regulations and controls. This U.S. Bureau of Mines report generally describes mine subsidence, the development of mine subsidence insurance programs, and the eight current programs in the United States. The States that have these subsidence programs include Colorado, lliinois, Indiana, Kentucky, Ohio, Pennsylvania, West Virginia. and Wyoming. Major aspects of the programs include history, administrative and operational procedures, insurable structures, recognition of mine subsidence, major exclusions, claims, insurance premiums, and the economic health of each program. Addresses of agencies involved with mine subsidence insurance are also given. Information within this report can be useful for residential and commercial property owners and mine operators. States that are considering starting or already have an existing mine subsidence insurance program can also use this report as a model for initiating or modifying programs.
Book Synopsis Surface Subsidence Engineering by : Syd Peng
Download or read book Surface Subsidence Engineering written by Syd Peng and published by CSIRO PUBLISHING. This book was released on 2020-09-01 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Underground coal mining disturbs both the overburden strata and the immediate floor strata. The subject of surface subsidence deals with the issues associated with the movement of overburden strata, which are the layers from the seam to the surface, where structures and water resources important to human activities are located. Surface Subsidence Engineering provides comprehensive coverage of the major issues associated with surface subsidence. The chapters are written by experts on surface subsidence in the three leading coal producing and consuming countries in the world: Australia, China and the United States. They discuss general features and terminologies, subsidence prediction, subsidence measurement techniques, subsidence impact on water bodies, subsidence damage, mitigation and control, and subsidence on abandoned coal mines. In addition, the final chapter addresses some of the unique features of surface subsidence found in Australian coal mines. The book provides information on coal seams ranging from flat to gently inclined to steep to ultra-steep seams. Written for mining engineers, geotechnical engineers and students of mining engineering, this book covers both theories and practices of surface subsidence. Unlike previous publications, it also deals with the subsidence impact on surface and groundwater bodies, crucial resources that are often neglected by subsidence researchers.

Available in PDF, EPUB and Kindle. Book excerpt: Subsidence movements due to various natural and manmade activities have been attracting attention of the people all over the globe because these movements have been affecting the life in many ways due to the impacts the movements cause to the surface, sub-surface and underground properties. Among the various subsidence causing activities the author has considered the underground mining in sedimentary deposits and withdrawal of water from the underground sources as the most important from the point of view of Indian scenario. Underground mining of sedimentary deposits in India has been going on for more than 225 years and as yet there is practically no indigenous literature available for the use of the mining operators, planners, students, etc. All these people in the country have to depend on the foreign literature although the knowledge of subsidence movements and their management is not only essential for underground mine planning but also for getting the environmental clearance and ensuring the safety of the underground workings. An analysis of the indigenously available literature revealed that there is an urgent necessity of simple but effective guidelines useful to the mining operators, etc. Therefore, the author has made an effort in this book to make the operators aware of the importance of subsidence management and then of the methodology for the management so that in majority of the situations they can take their own decisions and for the complicated cases they can seek expert advice. The activity of the withdrawal of water from the underground sources in the country is many decades old as for the various purposes, e.g., agriculture, industries, and domestic uses, water from these sources is being pumped out. Although, globally the subsidence movements due to this activity have attracted attention, the concern in India has not yet come to any age as hardly any literature is available on this subject. Keeping the above facts in view the following aspects of the subsidence movements due to the two activities have been discussed in this book. 1 Causes of subsidence movements 2 Impacts of subsidence movements 3 Potential areas in India 4 Dangers to underground workings 5 Two and three dimensional prediction of subsidence movement in sedimentary deposits with suitable examples 6 Prediction of the impacts of subsidence movements in sedimentary deposits with examples 7 Subsidence management in sedimentary deposits, including optimization of the subsidence movements with suitable examples, impact mitigation, management of subsided land for various uses, and converting impacts into resources 8 Monitoring of subsidence movements in mining areas and their interpretation 9 Subsidence prediction requirements 10 Five case studies of coal mining subsidence covering the situations of the extraction below surface properties and mine planning below forest areas The above for the sedimentary strata mining subsidence have been explained in such a manner that the mine officials at the site can use the subsidence management know-how without practically any difficulty. In respect of the subsidence movements due to withdrawal of water from the underground sources the following aspects have been outlined. 1 Phenomenon of subsidence due to ground water withdrawal 2 Factors that affect this subsidence 3 Impacts of the subsidence movements 4 Land subsidence management Since, this subject is not well developed in the country it has been suggested that an urgent attention should be given to develop the know-how so that the measure required to take care of the impacts of subsidence movements due to ground water withdrawal can be taken before any major problem comes up.

Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the results from the subsidence research study completed by the U.S. Bureau of Mines at the Roadside Mine, Powderhorn Coal Co., Palisade, Co. This research was conducted from February 1981 to August 1985, with additional data obtained during July 1991, to evaluate residual subsidence. The Bureau studied subsidence at three district room-and-pillar sections at separate locations over the mine and determined the maximum subsidence values and surface subsidence profiles for each mining section. Maximum subsidence of 3.0 ft occurred over the room-andpillar sections, with overburden depths ranging from 50 to 600 ft. Surface tension cracks had occurred, and were still evident during the residual subsidence survey.
