炮采工作面爆破工艺及参数的合理选择

Choosing Rationally Blasting Technology and its Parameters for Blasting Face

在炮采工作面中,合理的爆破工艺及炮眼布置可明显提高块煤率,提高效益;合理确定一次起爆炮眼数量既可减轻放炮工的劳动强度,又可实现安全、高效生产。本文介绍了炮采工作面爆破的一些新工艺和参数确定。

In the working face, reasonable blast technology and shot hole arrangement can raise recovery ratio and economics benefit obviously; determining reasonably the numbers of shot hole detonated one time can not only ease blaster＇s labor intensity, but also can carry out production safely and efficiently. In the paper, some newly technology and parameters＂ choosing methods in blasting face were introduced.
