| 摘要： | The Abandoned Underground Mine Inventory and Risk Assessment process, as documented in a recently adopted Ohio Department of Transportation (ODOT) manual, is a proactive response to the need to locate and assess the risk of all roadway sites beneath which abandoned underground mines exist. The overall purpose of this inventory and risk assessment effort is to enhance the safety of the traveling public by minimizing the possibility of a sudden roadway collapse that could result in fatalities or bodily injuries. Most of the abandoned underground mines in Ohio range in age from 50 to 150 years. Detailed abandonment maps are available for approximately 4,600 underground mines; however, for an estimated 2,000 mines, no detailed maps are available. The process comprises four basic activities: establishment of an inventory of all roadway sites beneath which abandoned underground mines may exist; assessment of risk; remediation of sites, if necessary; and permanent monitoring of sites. During development of the process, three notable mine remediation projects on interstate highways were undertaken by ODOT in response to roadway conditions suggesting mine-related subsidence activity: I-70 in Guernsey County, I-70 and I-77 interchange in Guernsey County, and I-470 in Belmont County. Cooperation in the development of the manual and subsequent workshops has led to the formation of a 13-state technical working group to continue sharing information and to cooperate on related research. |
