Presplit Blasting Technique in Treating Hard Overlying Strata: From Numerical Simulation to Field Practice
The potential dynamic risk of the mined underground space with hard overlying strata is one of the main concerns for coal operators. This paper presents a comprehensive study on treating the hard overlying strata upon the coal seam through the presplit blasting technique. The properties of the overl...
