1985～1987年，河北省文物研究所在北镇村、涧磁村、野北村和东西燕川村发掘了七处，总面积2000平方米，发现的遗迹有窑炉20座，作坊4处，其中包含有碾槽、水井、澄池、料缸、砖墁场地、匣钵、围墙等。

The tunnels were connected with millstones, land fortress, defense works in high buildings and temples. In addition, there were also commanding room, road signs, traps, kitchens, toilets and bunkers in the tunnels, and the entrances of the tunnels were ingeniously camouflaged by walls, grounds, livestock sheds, kitchen ranges and heated kangs.
