| 摘 要： | 根据“内外应力场”理论，建立了济三煤矿1301综放工作面沿空掘巷的结构力学模型，在此基础上确定了沿空掘巷的煤柱尺寸，预计了巷道围岩变形量，进而确定了巷道断面形式与参数。最后设计了巷道的支护型式及支护参数。

| Abstract: | On the basis of theory of internal-external stress fields,the structural mechanical model of NO.1301road driving along next goaf with fully mechanized top-caving in Jisan coal mine was established.The width of coal pillar of gob-side gateway was determined and the deformation of the surrounding rock was also calculated.Meanwhile,the type and size of gateway were given.At last,the supporting type and parameters of gateway were designed. |

| Keywords: | internal-external stress fields gob-side excavation supporting parameters |
