Coal Mine Roadway Driving
Coal mine roadway driving is a crucial part of any underground mining operation. The roadway is the main way to access the underground coal seams, and it must be carefully maintained and driven with extreme caution. Each mining company has its own procedures for roadway ......
degassing of steel
Steel degassing is the process of removing entrained gases from liquid steel. This is accomplished by holding the steel at a temperature, below the critical temperature of the alloy components, in order to dissolve the entrained gases into the steel. The gasses are then removed through controlled......
