Geotechnical Aspects of Overburden Materials for Stowing in Underground Coal Mines. The existing coal mine overburden dumps might be a good alternative for sand and provide a sustainable mining practice. Geotechnical and physicoChemical characterization is required to evaluate the suitability of OB dump material to be used as an alternative.

1 Disposal of coal refuse in an active surface mine shall comply with the performance standards set forth in Chapter 87 Subchapter D relating to surface coal mines minimum requirements for operation and reclamation plan and 90.125 and 90.128 relating to coal refuse disposal construction requirements and coal refuse disposal.
2016-3-31It is important to note that guidance such as Mine Safety and Health Administration MSHA for mine tailing ponds is not applicable to the Plant Hammond ash ponds. The preface, on page iii, of the MSHA Engineering and Design Manual, Coal Refuse Disposal Facilities May 2009, states as follows emphasis added.
WATER AND SLURRY BULKHEADS IN UNDERGROUND COAL MINES DESIGN, MONITORING, AND SAFETY CONCERNS S. Harteis, NIOSH, Pittsburgh, PA D. Dolinar, NIOSH, Pittsburgh, PA Abstract Many mining operations rely on bulkheads to provide a barrier between impounded water or slurry and active mine workings.
2 articleosti20026835, title Long term subsidence movements and behavior of subsidence-damaged structures, author Mahar, J W and Marino, G G, abstractNote Surface ground movement related to sag mine subsidence has been monitored above Illinois abandoned room and pillar coal workings for periods of more than 15 years. The long term movement related to a specific mine.
2020-6-11He has led major projects involving coal refuse disposal. His experience includes fresh water dam design, landslide investigation and remedial design, floodplain evaluation and permitting, corrective action planning, highway geotechnical investigation and design, abandoned mine land projects, and mine subsidence investigation and expert witness.

The present paper mainly deals with a case study of failed dump slope in western coalfield limited, Nagpur, India. A huge mass of debris flow had happened during the routine the activity of mining. The failed dump had a height of 75 m with 43 slope angle which had slipped forward by 18m. Representative loose dump material samples were collected from the site and tested to determine the.
Archived Interstate Technical Group on Abandoned Underground Mines The removal of the coal mine was not required if all voids were removed or fully collapsed during excavation. Intact coal typically was only removed if it was within five feet of the final subgrade elevation. One particular activity addressed during was the construction.
----- SECTION 2 SUMMARY OF FINDINGS AND POLLUTION CONTROL GUIDELINES FINDINGS Construction and Operation of Slurry Ponds and Refuse Piles Slurry Ponds Prior to 1972, coal refuse slurry ponds were often formed by dumping coarse refuse across narrow valleys to create embankments behind which fine refuse was placed hydraulically. Some of these.
Also, coal refuse piles, surface mine spoils, and unsealed deep mines were abandoned and now generate acid drainage. Since the advent of State and Federal regulations and reclamation fund taxes on coal production, the conditions and impacts from mining have improved.

This paper will discuss investigation methods, risk-based evaluation techniques, and remediation strategies that are employed to manage the hazards associated with shallow room and pillar coal mines. Key issues are the size of the development and its proximity to extensive mine workings, as well as the mitigation strategies that have been employed to remediate the mine workings for a wide.
2020-6-13The mine operator continued to place coarse coal refuse CCR on the saddle dike after the stability factor of safety had fallen below 1.5, which indicated that the weight of the CCR was overloading the fine coal refuse foundation. The mine operator was made aware of this potentially hazardous condition by the high pore pressure readings from.

Mining with stowing is an environmentally friendly way for coal mine, and stowing material is the key to realize environmental protection and harmonious development. This paper focused on the stowing materials, and evaluation for the stowing material would be made. Stowing materials could be sorted as chemical reaction material, solid refuses from coal mine and natural material for stowing.
