Blasting drilling space state testing device and method

The invention discloses a blasting drilling space state testing device and method, and the method comprises the steps: obtaining the stress of a stress piece on each segment, calculating the coordinates of the cross section where the stress piece is located and the axial intersection point of each segment according to the stress, connecting the coordinates of all segments, and obtaining the blasting drilling space state. The three-dimensional space state of the axis of the blasting drilling detection rod is obtained, existing straight line segment description is replaced, and therefore errors are reduced, and guiding of actual construction of a tunnel is facilitated. 本发明公开了本申请提供了一种爆破钻孔空间状态测试装置及测试方法，测试方法包括：获取每一个节段上应力片的应力大小，根据应力大小计算应力片所在的截面和每一个节段轴向交点的坐标，将各个节段的坐标连接起来，即得到爆破钻孔检测杆轴线处的三维空间状态，替代现有的直线线段描述，从而减小误差，有利于指导隧道的实际施工。
