Investigation of Subsidence along Segment of MO Rte 65, Springfield, Missouri
| 项目名称： | Investigation of Subsidence along Segment of MO Rte 65, Springfield, Missouri |
| 摘要： | Geophysical data (electrical resistivity and ground-penetrating radar) will be acquired on the mine ceiling and on the ground surface in an effort to determine the orientation, density and nature of pre-existing joints, if present. It is anticipated that the ground-penetrating radar (GPR) data will provide images of the roof rock to distances on the order of fifteen feet. The GPR tool should be capable of imaging fractures or clay-filled seams/fractures (if present) in close proximity to the mine ceiling. The electrical resistivity data will provide for significantly greater depths of investigation. Clay-filled seams/fractures (if present and sufficiently large) should be imaged on these data. |
