Damages of Underground Facilities in Coal Mines due to Gas Explosion Shock Waves: An Overview

With coal mining depth increase, gas explosion accidents due to the high gas emission rates often occur which cause significant casualties and property damages. Among them, gas explosion shock waves not only can destroy the machines and equipment in mine roadways but also cause the failure of mine v...
