Causes and Prevention for Sinkhole in Limestone Mine

  title={Causes and Prevention for Sinkhole in Limestone Mine},
  author={Ye-Jin Yang and Jin Myong Kim and Ji-Whan Ahn},
In recent, the placement of backfill in underground mines has emerged as a new paradigm in research as it not only improves safety but also allows disposal of byproducts including coal ash. In this regards, this paper addresses the backfilling challenges in limestone mine to prevent sinkhole and subsidence. Limestone mines, generally regarded as being safer than coal and metal mines, have been subject to unsupported mining methods. However, the increasing number of sinkholes worldwide has… Expand

Pot-Hole Subsidence Potentiality in Nongtrai Limestone Mine of Lafarge Umium Mining Private Limited, Shillong, Meghalaya
The Nongtrai limestone mine of Lafarge Umiam Mining Private Limited (LUMPL) is located in the East Khasi Hill district of Meghalaya. Limestone terrain is prone to solution features such as pot-holes.Expand


Systematic Selection and Application of Backfill in Underground Mines
The use of backfill in underground mining is increasing due to need for systematic backfilling of mine openings and workings. Backfill is defined as the material or materials that are utilised inExpand
Underground Mine Design and Stability Analysis at a Limestone Mine
Recently, the mining methods are changing from surface mining to underground mining because of the increment of the environmental issues and legal regulations. Therefore, the stability of undergroundExpand
Sinkhole subsidence due to mining
SummaryThis paper reviews the modes of formation of sinkhole subsidence associated with mining activities, drawing on examples in India. Sinkhole (pot-hole) subsidence is an abrupt local depressionExpand
A contribution to understanding the hardening process of cemented pastefill
Mine backfill has become a common practice in many modern mining operations around the world. Pastefill is an innovative tailings management method that returns much of this waste material to theExpand
Mining subsidence and its effect on the environment: some differing examples
Abstract The impact of mining subsidence on the environment can occasionally be very catastrophic, destroying property and even leading to the loss of life. Usually, however, such subsidence givesExpand
Property Evaluation of Tailings as the Mining Paste Backfill Material
Backfill can be classified into paste backfill, hydraulic backfill and rock backfill according to the filling materials and the transferring methods. This paper aims at using the tailings at SangdongExpand
Subsidence from underground defects is an increasing problem, and effective preventive or corrective measures depend on knowing the mechanism causing the failure. Too often, however, the mechanism isExpand
Characterisation of tailings for paste backfill system design
The focus of this work has been to investigate the status of backfill technology, in particular paste backfill, a relatively new technology. A rationale specifically for paste backfill system designExpand
Characterization of a new silica alumina-based backfill material utilizing large quantities of coal combustion byproducts
Abstract In this paper, a new silica alumina-based backfill material utilizing large quantities of coal combustion byproducts (CCPs) was investigated. The experimental results show that this materialExpand
Case Studies of a Borehole Deployable Robot for Limestone Mine Profiling and Mapping
The design of the robotic tool is discussed, its application in void assessment for prevention and response to subsidence is demonstrated, and results from a case study performed in the limestone mines of Kansas City, Kansas are presented. Expand
