摘　　要：某煤矿在2076巷道开采中存在掘进效率低的问题,月进尺不足90 m,严重影响了煤矿的产量。为此,在原爆破掘进+综采掘进开采工艺的基础上优化了爆破工艺,根据2076巷道实际情况改变爆破参数。经测试,优化掘进爆破工艺后,能在保障安全和经济性的前提下有效提高月进尺。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.

关 键 词：爆破掘进 工艺优化 月进尺
