Gas Control Technology by High Level Gas Drainage Tunnel in Fully Mechanized Caving Face
Abstract：With the increasing of mining depth, the gas emission in coal face of high - gas mine will become increasingly. Hebi coal group carries out the study of gas control technology of high level gas drainage tunnel. Matching with large diameter drainaging, the gas gauge problem in single low permeability coal seam is solved, and the high yield and efficient production in fully mechanized caving face is achieved too.
