摘要
以华丰煤矿典型巷道围岩松动圈的实测资料为基础,分析了配置200MHz 天线的探地雷达用于探测巷道围岩松动圈的科学性,探测深度小于10m 、探测精度达0.05m ,满足确定巷道围岩松动圈边界的基本要求.得出巷道围岩松动圈的发育具有结构特点,其中软弱结构起关键作用。
Basing on actual datum of broken zone of typical mining roadways in Huafeng coal mine, thispaper draws a conclusion that depth and accuracy are no more than 10 meters and up to 5 centimeters respectively to probe broken zone of rock mass correctly when the ground penetrating rader is equipped with 200MHz antennas. Moreover, it finds the development of broken zone has structural feasures and soft rock is key to stability of rock mass. It is a new field using GPR and is worth extending.
