| Abstract: | Through the analysis of working face support data recorder, from the support working resistance fre- quency distribution, force balance of left ＆ right pillar and the initial supporting force to analysis the selection of rationality of high cutting height support in shallowly buried seam, and analyzed the reason of the partial load and the smaller support setting force, eventually come to conclusion that support can adapt the requirements of working face |
