1) closure pumpage
截流抽水量
2) stopping flow and drainage
截流抽放
1.
Safe-rapid uncovering coal can be carried out, through ”stopping flow and drainage”, gas of coal around crosscut to be uncovered, and use the coal, which has no outburst danger formed after gas drainage, as resistance coal pillar against outburst, then carrying out intensified fast drainage the gas in coal to be uncovered, which has been ”no source water”, and elimination outburst.
通过对石门待揭煤体周边进行瓦斯“截流抽放”,并利用瓦斯抽放所形成的无突出危险煤体作为防突抵抗煤柱,再对待揭煤体内已成“无源之水”的瓦斯实施强力快速抽放消突,即可进行安全快速揭煤。
3) surface retention
地表截流水量
4) closure discharge
截流流量
5) intercepting sewage flow
截流量
