Case study of sinkholes over a Nebraska limestone mine Authors Siekmeier JA; Triplett TL; Powell LR Source developed within a 90 m by 105 m area on agricultural land overlying an abandoned section of an underground limestone mine It was determined that the subsiding area could enlarge due to three mechanisms: (1) caving and sliding of soil into the existing sinkholes, (2) new roof falls

Sinkhole formation above underground limestone quarries:

Historical records were used for the compilation of a database of sinkholes resulted from collapses of abandoned shallow underground limestone quarries (mines) in two villages in Belgian South Limburg During the last 350 years the formation of such sinkholes caused at least 38 casualties, but more often it caused a change in topography and damage to public and private property The objective

Foundation Problems In Limestone Areas A Case Study

Site investigations have time and again revealed the existence of numerous underground solution channels, cavities, sinkholes, etc that are associated with the limestone bedrock, as is typical of advance karst development in tropical terranes This paper presents a case study of foundation problems in limestone in the Kuala Lumpur area

Sinkhole hazard case histories in karst terrains

Collapse sinkholes, formed by failure of bedrock over a cavity, are rare in natural karst landscapes, but may be induced by excessive loading imposed on limestone that lies above an open cave; the risks associated with this geohazard should be eliminated by implementation of an appropriate site investigation that includes proof drilling Case studies to demonstrate the karst geohazard concern

from a case study performed in the limestone mines of Kansas City, Kansas 1 Introduction The existence of subterranean void spaces, such as the cavities created by mining, is a hazard to active mining operations and a constant threat to surface developments When abandoned, these underground spaces can accumulate tremendous quantities of water and threaten to flood encroaching active mines

The description of an effective sinkhole investigation

such as limestone, dolostone and gypsum) Sinkholes occur in various sizes, shapes (bowelshaped or vertical wall) and depths The development of sinkhole can be very gradual with continuous and gradual depression of the surface and can as well develop as a catastrophic event Most sinkholes are formed from a process in which carbon dioxide in the atmosphere

Investigation of Sinkhole Formation with Human Influence

Oklahoma is home to numerous sinkholes due to mining activities prominent in the area, Concerns over additional sinkhole development, and ways to predict them, have become a primary research topic within this area Several studies have investigated at the impact of early oil and gas activities in the Hendrick Field, which surrounds the Wink sinkholes along with sinkhole

Understanding Sinkholes and Their Solutions

Similar to solution sinkholes, these sinkholes occur gradually over long periods of time and appear as a gradual depression of the ground surface Cover collapse sinkholes generally occur where the overburden provides some limited stability, usually in clay soils, where limited surface drainage exists Over time, the rock dissolves in ground water leaving a significant void
