| 摘 要： | 地震波在不同状态的岩层中传播的速度不同,根据这一原理,利用KDZ1114-3型便携式矿井地质探测仪,接收岩层中传播的震波信息,解析得到震波速度,分析巷道围岩持征,而后确定巷道围岩松动圈范围,进而为巷道支护提供参考依据.

| Abstract: | The spreading spreads in the different rock are different. According toabove - mentioned principle, the information of earthquake vave spreading in the rock are received by the KDZ1114 - 3 portable surveying instrument and the spreeds of the earthquake vave are obtained after the information are analyzed. Then we analyze the characters of the rock around the tunnel and make sure of the slack circle of the rock around the tunnel. Finally the evidence are provided for the safequarding of the tunnel. |
