| Abstract: | In order to solve the problem of a great quantity gas gush of 14#,the Second Level of Left Second Spools of Pinggang Mine,this paper discusses the application of Gas Drawing and Releasing Technology of Empty Roof Mining Space.The concrete way is:to assign 4 drill field on the operation surface and 4 holes of every field are divided into parts and operated by relays assignment.The drill hold of effective drawing and releasing is assigned on the lower part of rock crack belt.After on drill hole is finished,polyurethane is used to seal the hold.Then two YS280SK4 drawing and releasing pump is used to alternately draw and release gas which can control exceeding return gas and make safe for production. |
