| 摘 要： | 通过研究顶板岩层在煤体上方倾向断裂的主要影响因素，分析了深井工作面沿空掘巷围岩的控制机理与技术对策，针对顾桥矿1116(1)综采面，结合现场工程地质条件，采用离散元软件UDEC对该工作面运输顺槽留设不同宽度煤柱进行数值模拟，得出最终的合理煤柱宽度，对今后类似条件下沿空掘巷的煤柱留设具有一定的推广意义。 |

| Abstract: | Through study on the major factor effected on the roof strata fracture along dip direction above coal, the control mechanism and technical countermeasure for surrounding rock deformation of roadway driving along goaf in deep well are analyzed, according to 1116(1) coal face in GuQiao Mine, combined with field engineering geological condition, numerical analysis about different coal pillar width of headentry of the working face was carried out with UDEC, the finial reasonable width of pillar is given. It is of extended significance for determination of coal pillar width for roadway driving along goaf with similar condition in other coal mine. |
| Keywords: | roadway driving along goaf deep well width of coal pillar numerical analysis |
