摘要(Abstract)：

为了加快岩巷掘进速度,应用准直孔掏槽和全断面一次爆破技术为河东煤矿设计了新的爆破方案,现场爆破效果超过了预期设想,爆破效率得到大幅提高,各项经济技术指标得到明显优化,成功地实现了准直孔掏槽全断面一次爆破。这2项技术为岩巷钻爆法掘进速度的提高提供了有力支持。
In order to accelerate the speed of rock drivage by drilling and blasting method,a new blasting scheme for Hedong coal mine has been designed with quasi-parallel cutting and full-face blasting technique,and the field blasting effect more than expected.Higher blasting efficiency was obtained,and various economic and technical indexes were optimized.Quasi-parallel cutting and full-face blasting technique were successfully achieved,thus indicates that these techniques could offer a powerful support for improving the speed of rock drivage by drilling and blasting method.
