郑家坡铁矿深孔爆破参数优化

Research on the optimization of deep- hole blasting parameters in Zhengjiapo Iron Mine

为了更好的运用深孔爆破,对其参数进行优化尤为重要.根据郑家坡铁矿的实际情况,通过正交试验法,采用扇形垂直深孔逐排起爆技术,对比分析了优化前后深孔爆破几个主要技术参数,并确定了合理的深孔凿岩爆破参数.该技术对类似矿山具有一定参考价值.

In order to better use the deep - hole blasting, to optimize the parameters is especially important. According to the actual situation of the Zhengjiapo Iron Mine, this paper, through the orthogonal experiment method, adopts the fan vertical deep hole by row blasting technology, and analyzes several main parameters of the deep hole blasting before and after optimization. The relative blast parameters for deep - hole blasting are confirmed. This technology is of referential values for other similar iron mines.
