Parameters of explosion-proof facilities to avoid air-blast in the context of underground ore mining

Abstract

The monograph concerns problems of explosion-proof facilities parameters substantiation to avoid air-blast while underground ore mining with the help of drill-and-fire systems. Strength and deformation features of bulkhead protective element have been tested; dependence of its carrying ability on perforation degree and structural component strength features has been determined. Results of theoretical, laboratory, and field research make it possible to substantiate parameters of air-proof bulkhead and develop recommendations concerning its application under specific mining and geological conditions. The monograph is for students, engineers, experts of higher educational institutions, research institutions, and design offices of ore mining branch.
