8/1/1999 - Technology NewsAn apparatus is described that advances the state of the art in gas content testing of coal or rock core samples. The design goals were to improve sensitivity/accuracy, durability, and ease of operation.
-
1/1/1995 - Reports of InvestigationsMany mines rely on toxic gas sensors to help maintain a safe and healthy work environment. This report describes a prototype monitoring system developed by the USBM that uses light to power and communicate with remote toxic gas sensors.
-
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.
-
9/18/2015 - Catalogs and indexes, Research areasNIOSH Mining Program page on blasting and explosives.
-
3/4/2014 - Contracts and cooperative agreementsA contract to evaluate the role of gas desorbing on the failure of coal and the resultant influence on dynamic failures such as bumps, bursts, and outbursts.
-
1/1/2011 - Book chaptersGases and fumes are generated as a result of explosives detonation at a blast site. This chapter discusses only those gases produced by the detonation of commercial explosives.
-
3/1/2010 - Peer reviewed journal articlesThis work presents a fractal porous medium model to predict gob porosity and permeability for controlling methane flow and to predict air leakage into the gob.
-
12/1/2009 - Peer reviewed journal articlesIn this paper, the production rate-pressure behaviors of six gob gas ventholes drilled over three adjacent panels were analyzed by using conventional multi-rate drawdown analysis techniques.
-
6/1/2009 - Peer reviewed journal articlesThis paper presents data on the limiting (minimum) oxygen concentration in the presence of added N2, methane, propane, ethylene, carbon monoxide, and hydrogen and some of their binary mixtures, and addresses flammable concentration limits.
