| Abstract: | How to improve blasting efficiency, improves blasting effect, increase footage, ensure roadway molding, still rock roadway blasting work should address the main issues. In combination with crushed rock blasting theoretical and practical experience in engineering, from the influence of various factors such as drilling and blasting effect starting. Affecting rock roadway in deep hole blasting speed and roadway excavation quality borehole depth, undercutting blasting and smooth blasting, directional fracture controlled blasting some technical issues such as more detailed analysis and research. Made more reasonable undercutting form and undercutting arguments, light burst charging structure and optical burst parameters and directional fracture controlled blasting technology and construction management organization. |
