| Abstract: | In order to solve the problem that high filling ratio was difficult to reach in flat seam cemented filling of fully mechanized coalface 2307 in Yuyang coal mine,some filling technologies were proposed,such as rational choice of location for filling head,segmentation filling of filling area,filling flow control during the operation. Engineering practice showed that the average filling ratio of the filling area was as high as more than 98. 5%,and the filling effect was very well. The filling technologies were also applicable to other kinds of cemented filling coalface,such as strip mining,continuous mining. |
