| 摘 要： | 新-煤矿施工-投料孔，因钻孔偏斜，未打到大巷中，为测定其终孔位置，采用了地震直达波方法，即将地面设计的输料钻孔座标投影到-253m的大巷中，在其周围有规则的布设24道检波器，将少量炸药下到投料孔底部进行激发，根据初至波时间确定投料孔的终孔位置。

| Abstract: | A bateh charging borehole was drilled in Xinyi coalmine, had not reached to the target base road because of deviation. To locate the borehole bottom, the seismic direct wave method was used. The designed borehole coordinates were projected to -253m base road, then set 24 geophones around the projected point, shot a small quantity of powder in drilled charging borehole bottom, to determine the bottom location according to the first arrival time. |

| Keywords: | first arrival time direct wave borehole bottom location drill hole seismic method |
