| 摘 要： | 大断面深井施工由于其施工工艺复杂、施工安全风险高,一直被视为矿山企业高危作业工程之一。为了探究大断面深井施工成井技术,通过介绍一种大断面深井施工工艺,以施工导井为自由面,通过合理的爆破方案一次性将40m垂深的导井爆破扩井成型,极大地简化了工艺,降低安全风险,并在实践中取得了良好的效果。

| Abstract: | Construction of large section deep well has been regarded as one of the high-risk operation projects in mining enterprises because of its complicated construction technology and high construction safety risk.In order to explore the well completion technology of large section deep shaft excavation, this paper introduces a construction technology of large section deep well, taking the construction direction guidance shaft as free surface, and blasting the 40m vertical guide shaft at one-step by a reasonable blasting scheme, which greatly simplifies the process, reduces the safety risk, and achieves good results in practice. |
