铁矿

In combination with the blasting practice at Nanfen Open pit Iron Mine,research was made on utilizing advanced testing instrument in the main adit to supervise the open pit longhole blasting. The related data of adit blasting vibration were analyzed sysmatically and a blasting vibration formula suitable for the geological conditions of the mine was given so as to provide the mine blasting design with scientific basis.

结合南芬露天铁矿生产爆破实际，研究了利用先进的测试仪器在主平硐内对露天深孔爆破进行监测，并对平硐爆破振动的有关数据进行了系统的分析，提出了适用于该矿地质条件下的爆破振动公式，为矿山的爆破设计提供了科学的依据。

In grinding, changing the liquid of grinding dosage will improve grinding rate, and the selection of aidant grinding dosage shall start from dispersive aidant grinding dosage.
