摘要

A systematic methane outflow measurement experiment was conducted in coal face 301 of coal mining in No.1 colliery of Huangling. Through analysis on the data of the measurement experiment, it is concluded that: (1) the proportion of over-limited state is 7.85% and critical state reach 16.94% in upper corner of coal face 301 ; (2) the methane outflow increase sharply with the air flow rate increase suddenly in some time ; (3) Malconformation is the main characteristic of methane emission in coal face 301; (4) The ratio of methane outflow comes from gob to the methane outflow in the whole work face is 65.8%; (5) the methane emission from adjacent coal seam and adjacent rock is the main gob methane emission sources.
