The paper introduces the method for determining resonable chamber blastingparameters by the blasting funnel test in Yugou Limestone Mine. 介绍了峪沟石灰石矿的硐室爆破中通过爆破漏斗试验确定合理的硐室爆破参数的方法。
The experiment carried uot in the Wulongquan Limestone Mine expresses the determined weight is reasonable and would be used to guide the actual cavity hole-springing explosion. 在乌龙泉石灰石矿进行了现场试验，试验所确定的用药量是合理的，可以用来指导实际的爆炸扩腔。
