Study on the disaster reduction mechanism of presplitting blasting and reasonable blasting parameters for shallowly buried remnant pillars
Abstract Disasters such as support crushing easily occur at the mining face under a shallowly buried remnant pillar; therefore, a method for presplitting blasting remnant pillars to relieve stress concentrations and reduce disaster occurrence is proposed. Based on the geological conditions of Nanlia...
