| Abstract: | Controllable drawing roof coal mining method is applied either to gently inclined seam or to steep seam. The author summs up four corresponding methods according to conditions of our country, analyse the coal-recovering effects and proves applicated conditions and measures for improving by "Drawing Coal Theory of the Ellipsoid". Its conclusion basically consists with practice. |
