大直徑藥包爆破是苏联的一项先进經驗。在我国許多矿山大断面坑道掘进中推行的結果是比較好的。但在小断面探矿坑道掘进中,尚缺乏試驗研究。本文对此问題作了初步試驗,但有些問題的論据尚不足,如在小断面坑道中减少炮眼数目有限,不能节省总鑽眼的时間問題:采用大直徑藥包爆破,不能采用直線掏槽問題等都需进一步試驗。希大家对这一經驗的应用发表意見,以便作出相应的結論,提高爆破技术。
Large-diameter cartridge explosions is an advanced Soviet experience. The results of many large-scale mine tunnel excavation in our country is better. However, in the small-section prospecting tunnel excavation, there is still no experimental research. This article made a preliminary test of this issue, but some of the arguments are not enough, such as reducing the number of small holes in small tunnels limited number of drilling can not save the total time of the problem: the use of large diameter drug bag blasting can not be used straight to dig Trough problems need further testing. Let us express our opinions on the application of this experience in order to make corresponding conclusions and to improve the blasting technology.
