| 1 | Analysis of roof and pillar failure associated with weak floor at a limestone mine显示文摘A limestone mine in Ohio has had instability problems that have led to massive roof falls extending to the surface. This study focuses on the role that weak, moisture-sensitive floor has in the instability issues.Previous NIOSH research related to this subject did not include analysis for weak floor or weak bands and recommended that when such issues arise they should be investigated further using a more advanced analysis. Therefore, to further investigate the observed instability occurring on a large scale at the Ohio mine, FLAC3 D numerical models were employed to demonstrate the effect that a weak floor has on roof and pillar stability. This case study will provide important information to limestone mine operators regarding the impact of weak floor causing the potential for roof collapse, pillar failure, and subsequent subsidence of the ground surface. | Murphy Michael M.

| 2 | Determination of volumetric changes at an underground stone mine: a photogrammetry case study显示文摘Photogrammetry,as a tool for monitoring underground mine deformation,is an alternative to traditional point measurement devices,and may be capable of accurate measurements in situations where technologies such as laser scanning are unsuited,undesired,or cost-prohibitive. An underground limestone mine in Ohio is used as a test case for monitoring of structurally unstable pillars. Seven pillars were photographed over in a 63 day period,punctuated by four visits. Using photogrammetry,point clouds of the mine geometry were obtained and triangulation surfaces were generated to determine volumes of change over time. Pillar spalling in the range of 0.29–4.03 m^3 of rock on individual rib faces was detected.Isolated incidents of rock expansion prior to failure,and the isolated failure of a weak shale band were also observed. Much of the pillars remained unchanged during the monitoring period,which is indicative of proper alignment in the triangulated surfaces. The photographs of some ribs were of either too poor quality or had insufficient overlap,and were not included. However,photogrammetry was successfully applied to multiple ribs in quantifying the pillar geometry change over time. | Slaker Brent Westman Erik Ellenberger John Murphy Michael | 2016 | International Journal of Mining Science and Technology2016，26，1： | 2 |
