Smooth Blasting Technology in Mine Rock Roadway under Microscope Technology
Since the advent of the microscope, after more than ten years of technical improvement and applied research, it has promoted the rapid development of the seven branches of nanotechnology. Atomic force microscopy, especially in applied research in biology, life sciences and materials science, has gained high scientific value. The use of microscopy to determine the porosity of mine rocks has become the primary method for determining the porosity of mine rocks. This method is used to study the porosity of rock, the accuracy is high, and the information obtained is much. Microscopy technology to determine mine rock can effectively improve the speed of excavation. In the rock roadway boring blasting, because the boring working face is relatively small, the clip is made larger, and if the traditional blasting technology is still used, the roadway will be over-excavated seriously. The surrounding rock is disturbed and damaged, which increases the difficulty of support and the cost of support. Affecting construction quality also affects construction progress. In view of this; the following paper focuses on the application of smooth blasting technology under microscope technology in mine rock roadway excavation. The blasting parameters optimization and blasting effect evaluation of rock roadway were carried out. According to statistical experiments, the strong aquifer (porosity >10%) accounted for 43.5% of the whole stratum. Weak aquifer (porosity 15%~10%), accounting for 44.9% of the stratum. The water barrier layer (porosity <15%), accounting for 10.1% and the strong aquifer accounts for about 32% accounted for 36% the structure of the mine rock is clear and identifiable. The research results have certain reference value for improving the blasting effect of similar mine rock roadway, improving the tunneling efficiency, improving the support effect and reducing the rock tunneling cost.
