详细介绍了邢东煤矿副井井筒深孔光爆施工情况。所采用的光爆参数经施工证明是合理可行的 ,爆破深度和质量都达到了较高水平。施工速度快 ,掘砌成形好 ,基岩段施工连续 5个月月进尺达上百米 ,最高月进达 190 8m ,平均月进达14 3 0 6m。
Described in detail Xingdong coal mine shaft borehole light burst explosion construction situation. The light burst parameters adopted by the construction proved to be reasonable and feasible, the blasting depth and quality have reached a higher level. The construction speed is fast and the excavation and formation are good. The construction of bedrock sections reaches a succession of 100 meters for 5 months in a row, with the maximum reaching 1908m and the average monthly reaching 14,300m.
