Systems for enhanced in-situ or perhaps even ex-situ biogenic methane production from hydrocarbon-bearing formations () including coal seam, oil shale, coal, coal derivates and the like are presented in embodiments such as but not limited to: increasing and perhaps even selection of microbial populations (), amending CBM water and other microbe-containing media, diminishing sulfate reduction competition, enhancing organic matter concentrations and generation of biogenic methane (), universally treating hydrocarbon-bearing formations, and introducing amendments () to hydrocarbon-bearing formations.

Biogenic methane production enhancement systems

A support member for supporting a roof of a subsurface space. The support member may include a base portion for defining a surface area to contact a ceiling of the subsurface space. One or more sockets may extend from the base for defining openings for receiving roof bolts therethrough. Accordingly, the support member may be configured to function as a washer for the roof bolts to support the roof material above the ceiling. The sockets may include covers for preventing the roof bolts from extending out of the sockets. The sockets may be oriented at angles with respect to the base such that when roof bolts are placed in the sockets, the roof bolts may extend at angles with respect to each other in a splayed configuration.

Method for supporting a subsurface material

A method of mining substantially horizontal beds of trona ore, such as are found in the vicinity of the town of Green River, Wyoming, in which substantially all the ore within a given area is extracted. Mining is accomplished by driving substantially parallel entries into the trona formation approximately 100 to 200 feet apart, connecting the entries by at least one primary passage which thereby defines a trona panel, supporting the roof of the primary passage by movable roof supporting structures, and mining the exposed short face or wall of the trona panel. The mined material is removed and the roof supporting structures are advanced so that the structures remain essentially adjacent and parallel to the panel face being mined as it recedes. The roof supporting structures are continuously advanced incrementally to effect caving of the previously supported roof and facilitate mining of the exposed short face of the trona panel.
