  • Summary: [−]
    Loose-dumped mine spoil has been proven to successfully promote tree growth. By understanding the hydrological and water quality characteristics of loose-dumped mine spoil, this practice can be incorporated into alternative head-of-hollow fill designs options to address these environmental concerns.

  • Summary: [−]
    A comparison of the runoff curve numbers for southeastern Kentucky Appalachian forest to reclamation using loose-dumped mine spoil was completed. Based on this preliminary data it appears that loose-dumped mine will reduce peak flow and runoff volume below forested conditions.

  • Abstract [−]
  Head-of-hollow fills have gained national attention due to increasing environmental concerns, particularly with regards to headwater stream loss. Researchers at the University of Kentucky in conjunction with outside scientists and consultants in the fields of stream restoration, wetland restoration, and mined land reclamation have developed new design methodologies for creating a headwater stream system for a head-of-hollow fill located on University of Kentucky property in eastern Kentucky. The design was largely built on the Forestry Reclamation Approach, which encourages a non-compacted spoil medium to promote tree growth, in an effort to address concerns related to water quantity and quality as well as habitat development. Prior water quantity and quality monitoring at the head-of-hollow fill in conjunction with controlled experiments of the hydrologic characteristics of loose dumped spoil material were utilized in the design process. The major components of the design included 1) modifying the head-of-hollow fill crown geometry, 2) compaction of portions of the crown to control infiltration, 3) creation of a clay under-lined, two-stage channel across the crown, 4) use of loose-dumped to promote tree growth, 5) development and/or enhancement a variety of ephemeral channels utilizing rock and/or wood materials, 6) creation of vernal ponds for energy dissipation and habitat enhancement, and 7) modification of an existing wetland to improve water quality. To determine the ability of this design to improve both water quality and habitat, which are both key goals of the project, the monitoring program will focus on comparing the implemented design to other head-of-hollow fills that were constructed by typical means as well as to an un-mined neighboring watershed.

Prior water quantity and quality monitoring at the head-of-hollow fill in conjunction with controlled experiments of the hydrologic characteristics of loose dumped spoil material were utilized in the design process. The major components of the design included 1) minor modifications to the head-of-hollow fill geometry, 2) compaction of portions of the head-of-hollow fill to control infiltration, 3) creation of a two-stage channel across the crown of the fill, 4) use of uncompacted spoil to promote tree growth, 5) development and/or enhancement of a variety ephemeral channels using different design that utilized rock and/or wood materials, 6) implementation of vernal ponds for energy dissipation and habitat enhancement, and 7) modification of an existing wetland to improve water quality. To determine the ability of this design to improve both water quality and habitat, key goals of the project, the monitoring program will focus on comparing the implemented design to other head-of-hollow fills that were constructed by typical means as well as to an un-mined neighboring watershed.

Presented at: Stream Restoration Conference in the Southeast: Accomplishments and Opportunities, October 2-5, 2006, Charlotte, NC.
  
  
  • Abstract [−]
  The mining technique of mountain top removal, and subsequently valley filling, is a common practice in Appalachia. The development of practical stream restoration/rehabilitation techniques for post-mined lands, specifically head-of-hollow fills is needed to regain lost headwater stream system value. Important to note is that these techniques must be 1) all encompassing of the valuable functions of headwater stream systems and 2) economically feasible for the mining companies to implement for both currently constructed and future head-of-hollow fills. Recognizing the need for such techniques, the University of Kentucky has led the effort to develop new methods for restoring headwater stream systems on head-of-hollow fills. Using monies secured through the Commonwealth of Kentucky’s mitigation bank, the University of Kentucky in partnership with outside scientists and consultants in the fields of stream restoration, wetland restoration, and mined land reclamation have designed a headwater stream system for a head-of-hollow fill located on University of Kentucky property in eastern Kentucky. Once fully constructed, this site will function not only as a research laboratory, but also as an outdoor classroom promoting technology transfer to consultants, mining personnel, regulators, educators, and environmental groups. If a paradigm shift in head-of-hollow fill design is to occur, education of the public must play a central role.

  • Abstract [−]
  Head-of-hollow fills have gained attention due to increasing environmental concerns. Researchers at the University of Kentucky are exploring alternate head-of-hollow fill design options that build upon the Forestry Reclamation Approach and address these concerns. To better assess the hydrologic characteristics of loose dumped spoil material, a research effort was undertaken in eastern Kentucky. Water quantity and quality from six one-acre plots consisting of two replications each of 1) brown weathered sandstone, 2) gray un-weathered sandstone, and 3) mixed brown weathered sandstone, gray un-weathered sandstone, and shale are being monitored. Preliminary results suggest differences are present between the spoil types.
