摘要
主要介绍了在盲竖井开拓掘进过程中，由于受井下平面、空间等方面条件的制约，在井壁支护的方案选择上，具体分析井筒所穿过岩体的工程地质、水文地质状况，采用合理的支护方案，灵活应用喷射混凝土、锚喷、锚喷网等联合支护型式，进行井壁永久性支护，提高了井筒施工速度，缩短建井工期，减少投资，提高经济效益。
Because of the restriction of shaft space in the blind shaft development, the engineeringgeological and hydrogeologic conditions of shaft passed are considered when shaft support plan areselected. Suitble plan and combined support of concrete spraying, bolt-spray and bolting wire meshare used to make shaft support permanent. This method can increase the pace and curtail the timeof shaft construction, reduce the investment and improve economic benefit..
