More Information
Summary:The invention relates to a full-section blast hole positioning device and method based on a central projection principle. The full-section blast hole positioning device is arranged in a rock stratum tunneling roadway or tunnel. Based on the central projection principle, the distance between an enhanced point light source and a blast hole positioning model plate is adjusted, and a reasonable ratioof the distance between the blast hole positioning model plate and a section is formed; meanwhile, the manufacturing mode of the blast hole positioning model plate is flexibly changed according to theblasting process, the blast hole arrangement mode, the blast hole number and the hole diameter size which are formulated according to geological conditions and the tunneling section shape, and it isguaranteed that laser beams penetrating through the prefabricated blast hole positioning model plate can completely cover the roadway or tunnel tunneling section; and all blast holes are accurately positioned in the whole secti
