1/1/2000 - Conference papersThe practical application of the "advance and relieve" method is discussed. A trial of the method was conducted for a room and pillar coal operation that was experiencing roof cutters and long running roof falls caused by high horizontal stresses.
-
1/1/1991 - Reports of InvestigationsThis report details the results of a series of large-scale experiments where small coal fires were used to ignite the conveyor belt at specific air velocities, and showed conditions required for early detection of conveyor belt entry fires.
-
9/9/2024A partnership between the NIOSH Mining Program and its stakeholders to investigate the use of existing stability/subsidence monitoring technologies.
-
5/30/2024 - Contact informationContact information for the NIOSH Mining office.
-
1/13/2023 - Research projectsA project to build the framework for expanding pillar design criteria into challenging environments by undertaking pillar response investigations in representative conditions at case study mine sites.
-
11/29/2022 - Research projectsA project to determine the need for improved bench design guidelines and develop slope monitoring radar guidelines for application to open pit mines.
-
11/8/2022 - Research projectsA project to increase the safety of open pit mines through improving upon or developing new rockfall catch bench design guidelines and improving slope performance monitoring capabilities at open pit and quarry sites.
-
9/18/2020 - Research projectsA project to address the lack of information on longwall-induced subsurface strata deformations and stresses and their effect on shale gas well casings by conducting detailed analysis and instrumentation on unconventional shale gas wells.
-
9/16/2020 - Research projectsA project to evaluate and quantify subsurface overburden deformations in longwall abutment pillars under shallow overburden depths, and to employ field instrumentation results and 3D numerical modeling to identify critical parameters.
-
9/1/2020 - Peer reviewed journal articlesAn article presenting an analytical model of gas transport through fractures in a low permeable stratum.
