Three coal mine gob degasification studies using surface foreholes and a bleeder system 10 p. (OCoLC) Online version: Maksimovic, S.D. Three coal mine gob degasification studies using surface foreholes and a bleeder system. [Washington, D.C.]: U.S. Dept. of the Interior, Bureau of Mines, (OCoLC) Online version. The use of vertical surface degasification boreholes with bleeder systems and the use of a timbered bleeder system to degasify gob areas were studied by the Bureau of Mines. This report describes three gob degasification studies conducted in the Pittsburgh coalbed. One study was conducted to determine the number of panels degasified with one large borehole. The study showed that the borehole provided degasification for three panels. Another study was conducted during the retreat of a acre panel with a single- entry and a two-entry bleeder system and a large surface borehole. Additional Physical Format: Maksimovic, S.D.

Bleeder Ventilation System. In the U.S., most underground coal mines utilize a bleeder ventilation system to ventilate the mined out panels and the gob area of the active panel. In our study, this situation is simulated with two panels, one as a mined-out panel and the other one as an active panel, utilizing a bleeder system ventilated by.
