摘要：">According to the mountainous shallow-buried coal seam mining engineering geological conditions in Guizhou Fa'er coal mine, it researched the slope breaking and displacement characteristics when mountainous shallow-buried coal seam mined with similar material simulation method. The results showed that: (1) based on the slope movement characteristics, the mountainous coal seam overlying strata could be divided into two regions -"breaking movement area" and "common movement area". "Breaking movement area" belonged to shallow-buried coal seam and "common shift area" belonged to common depth coal seam. (2) When mountainous shallow-buried coal seam mined, its overlying strata could turned to be "multilateral structure". They were relative to slope morphology and tensile cracks. Its movement characteristics were dumping to the goaf behind the working face, and then slide along the fracture surface. Its trajectory was "S" type. (3) When mountainous coal seam mined, overlying strata would produce lateral displacement with direction to the free surface. © 2013 Taylor & Francis Group.
