水利工程施工考试复习资料（Review data of hydraulic engineering construction examination） Powdery ammonium nitrate explosive, AN-TNT explosive, ANFO ammonium, pine wax for explosive Containing nitro amine explosive: slurry explosive, water gel explosive, emulsion explosive Types of detonators: Fire detonators, electric detonators, and detonating detonators The type of detonating materials: fuse, detonating cord and relay tube, nonel tube and nonel tube connecting element Detonation method: non electric detonation, electric initiation, non electric detonation, including fuse, nonel tube, detonating fuse and detonating charge Blasting parameters: unit explosive consumption, hole diameter and hole depth, chassis resistance line, hole depth, hole hole spacing and spacing, charge calculation, detonation network Blasting construction includes rock drilling technology and blasting operation technology Procedures for blasting operations: preparation, handling of explosives, charging, network connection, explosion warning, initiation, post explosion inspection Blasting hazards: blasting, blasting shock wave and shock wave, blasting flyrocks (300m minimum safetyspacing) Grouting with grouting pressure greater than 3~4MPa is called high-pressure grouting. High pressure grouting is used in the high dam. Grouting construction procedures include: grouting hole location, drilling, drilling (fissure) flushing, water pressure test, slurry allocation, grouting slurry, grouting end, grouting quality inspection Grouting pressure is the pressure of the grout in the middle of the grouting section Drilling and grouting methods: drilling, full drilling, full hole drilling, full bore drilling, top-down method, bottom-up method, comprehensive grouting method and orifice sealing method End of grouting condition: one is residual pulp and one is pulp closing time Borehole grouting method in sand and Gravel Formations: pipe grouting, casing grouting, cyclic drilling and pre grouting Natural resources: natural
