摘要
为获取会泽铅锌矿准确的炮孔间距参数,在该矿深部进行了一系列多孔距同段爆破漏斗实验,测量了爆破实验数据。根据实验数据和绘制的多孔距同段爆破漏斗底圆断面轮廓线及爆破沟槽轮廓线,认为炮孔间距以0.6m以内比较合理。实验结果将对优化会泽铅锌矿爆破参数具有实际指导意义。
In order to obtain the accurate distance between the blasting holes for the deep mining of Huize lead-zinc mine,a series of experiments of multi-holes blasting crater with same detonators were carried out.The blasting crater curves were drawn accurding to the experimental data.The experimental results showed that if the distance between the blasting holes is prescribed with 0.6 m,it will occur good effects.The experiment provide effective technical support for deep mining of Huize lead-zinc mine.
