自七十年代我矿全面推广使用喷锚支护新技术以来,一直取得了良好的经济效果,使用范围从平巷、竖井发展到大断面硐室,实践表明,这项新技术的实施质量可靠、节约人力物力,施工简单、劳动强度低、速度快、同时还能收到减少开挖量的效果,因此它确能为井巷的快速掘进提供良好条件,在总结经验的基础上现将其实践及理论初步探讨分述于后。 Since the seventies of the mine to promote the use of Spray and Anchor Support new technology has been achieved good economic results, the use of range from the drift, the shaft to the development of large cross-section chamber, the practice shows that the implementation of this new technology reliable quality , Save manpower and material resources, simple construction, low labor intensity, high speed, and also receive the effect of reducing the amount of excavation. Therefore, it can provide good conditions for rapid tunneling. On the basis of summarizing the experience, Practice and theory of the initial discussion divided in the post.
