Abstract
The characteristics of geological conditions and mining technology at the coal mines of Coal Stock Company Vorkutaugol are given in the article. Information about longwall panel ventilation schemes and problems caused by high methane emission is also presented. The results of experiments at longwall panels using the methane emission control ventilation complex are described as well as ways of isolating gob methane removal. Other topics include the methane emission control ventilation complex consisted of drainage entry, an isolating wall with windows, mixing chambers and regulating stoppings. As results of experiments have shown, the most effective gas emission control methods were: the application of gas sucking fans for the isolated gob methane removal, and isolating walls at the line exposed to the gob. Encouraging results were obtained by use of two-entry mining system with yielding pillar between entries, homotropal ventilation and isolated methane removal from the gob.
