【摘要】 随着煤矿井工开采技术的进步,不仅要求快速机械化掘进,且对井筒工程提出了新要求。采用反井钻机工艺实现井筒快速施工,充分利用反井钻机施工小直径钻孔速度快、质量好、钻爆法破岩效率高等特点。这种工艺主要包括用反井钻机钻井和钻爆法刷大,并通过实例介绍了反井施工工艺技术。更多还原

【Abstract】 Mining technology innovation not only requires fast comprehensive mechanized driving,but also makes a new demand for shaft construction.With small diameter,speedy drilling,good quality,and efficient rock-breaking,raise-boring machine could realize the fast shaft construction.This technique includes raise-boring machine and drilling-and-blasting method.The construction technology is illustrated with examples.更多还原
