摘要
根据张集煤矿1213(3)工作面的地质条件,应用大型有限元程序ANSYS对不同尺寸煤柱条件下掘巷及回采时围岩应力、变形进行了分析,指出厚煤层沿空掘巷锚杆支护合理的煤柱尺寸以5m左右为最佳。
According to geology conditions of the 1213 （ 3 ） face of Zhangji coal mine, By ANSYS the paper analyzed dint and displacement of round rock of roadways driving along next gob supported by bolting and meshing under the different size coal pillar condition, and points out that the rational width of small coal pillar is 5 m or so.
