| 摘 要： | 在立井施工中,掘、砌混合作业是一种快速施工方法。采用的施工段高合理与否直接影响围岩稳定,作业安全,横板型式,循环工作组织和凿开设备选择,施工段高是一组重要工艺参数。通过对伞形钻架钻孔分析,得出确保最佳边眼角和最佳边眼开口位置的合理施工段高为3.1至8.4m。

| Abstract: | In the construction of a shaft,the mixed operation of coalling and sinking is a fast sinking method.
It has direct influence on stability of wall rock, operation safety, the type of model plate,circular working organization and the choice of sinking equiment whether the adopted section height of construction is reasonable or not. The section height of construction is an important technical parameter.
Through the analysis of drilling on the umbrella-type boring frame, the reasonable section height of construction obtained is 3.1 to 8.4 meters under the ensured sinking condition of optimal skew angle and the position of the optimal opening of the surrounding bla-stholes. |
