Blasting Technology of Large Section Rock Roadway in Coal Mine
A coal mine in 2076 roadway mining has the problem of low tunneling efficiency,the monthly footage is less than 90 m,which seriously affects the coal mine output.Therefore,based on the original blasting excavation+fully mechanized mining technology,the blasting process was optimized,and the blasting parameters were changed according to the actual situation of the 2076 roadway.After testing,it has been found that optimizing the excavation and blasting process can effectively increase the monthly footage while ensuring safety and economy.
