为了适应机械化采煤发展的需要,采区巷道布置正在作出相应的调整。而采区巷道布置的改进又导致了采区回风方式的改变,由普遍采用传统的采区中央回风方式开始出现使用采区边界回风的新趋势。如跨越多组上山(或石门)连续开采布置,“Z”形往复式开采等布置,均采用采区边界回风方式。可以预见,随着机械化采煤的发展,采区巷道布置的改进,采区边界回风方式将会被广泛的使用。因此,进一步研讨采区边界回风问题具有很现实的意义。
In order to meet the needs of the development of mechanized coal mining, mining area roadway layout is being adjusted accordingly. However, the improvement of roadway layout in mining area has led to the change of the way of return air in the mining area. The new trend of using the boundary of the mining area to return the air began to appear by adopting the traditional method of central return air in the mining area. Such as more than a group of uphill (or Shimen) continuous mining layout, “Z” -shaped reciprocating mining layout, adopt the mining area border return air way. It is foreseeable that along with the development of mechanized coal mining, improvement of roadway layout in mining area and return air return at the border of mining area, it will be widely used. Therefore, further research on the issue of return air at the mining area boundary has very realistic significance.
