摘要
传统的中深孔炮孔现场定位布置方法,是由爆破工程师采用目测与简单的量具对爆破区域地形进行粗略估量,得出相应的爆破参数,然后根据现场情况进行孔网设计和标定。由于参数采集过程的粗略,很难精确地采集到爆破台阶高度、底盘抵抗线和前排孔的实际抵抗线等一些重要的参数,由此可能产生爆破弱面和抵抗线过大等问题,为爆破安全、质量埋下隐患。哈尔乌素项目部采用现代电子测绘技术与爆破技术相结合,提出一种中深孔爆破炮孔精确定位的新方法,很好地解决了这一问题。
The traditional method of hole-location in medium and deep hole blasting were according to engineer＇s rough estimation for blasting region landform by eyenaked or with some simple measures, by tbis mean the parameters were made out and then adjusted in practice. It is difficult to precisely collect some important parameters such as bench height, bottom burden and actual burden of frontal line by rough estimation,so weak surface and larger burden would be caused and potential dangers would exist. The problem was well solved in haerwusu（哈尔乌素） project department by proposing a new method which combines the modem electronic surveying with blasting.,
