中文摘要:为解决单一突出厚煤层下行开采下分层过上分层切眼问题,提出了下分层工作面伪斜布置的方式解决工作面过空顶或未完全跨落区域的技术方案及工作面伪斜布置参数;赵固二矿11072工作面伪斜布置现场施工后实现了安全高效回采,对类似条件矿井具有很好的示范作用。

Discussion on the influence of air flow on coal sample desorption in sampling process
Abstract:In order to solve the problem of slicing under slicing above slicing in downward mining of single outburst thick seam, the method and parameters of pseudo inclined arrangement for lower level working face are put forward to solve the problem that the working face passes through the empty roof or not completely across the falling area. the safe and efficient mining has been realized after the site construction of 11072 working face in Zhaogu No. 2 Coal Mine, which has a good demonstration effect for similar conditions.
keywords:Single thick seam  cut hole  downward mining  pseudo inclined  parameter.
