Preferably, the distance between described two neighboring perforating bullet mounting groove axis is less than 105mm.
Preferably, the described first zinc-plated pipe connections and the second zinc-plated pipe connections are the zinc-plated pipe connections of taper, instead of
Square endplate, it is possible to reduce friction of the perforating bullet firing mount installation process middle hole wall to firing mount, convenient for powder charge.
Preferably, the of length no more than 1m of the firing mount can overcome influence of the drilling construction process there are degree of skewness.
Compared with prior art, the advantageous effect of the utility model acquisition is：
A kind of coal mine down-hole drilling perforating bullet firing mount provided by the utility model, the of length no more than 1m of perforating bullet firing mount,
Influence of the drilling construction process there are degree of skewness can be overcome；Perforating bullet firing mount both ends use the zinc-plated pipe connections replacement side of taper
Shape end plate, it is possible to reduce friction of the perforating bullet firing mount installation process middle hole wall to firing mount, convenient for powder charge；Perforating bullet mounting groove axis
Between angle be 45 °, can be with multi-faceted pressure break coal seam.
A kind of coal mine down-hole drilling perforating bullet firing mount provided by the utility model, frame body both ends are welded the first galvanized pipe and are connected
Fitting, the other end weld the second zinc-plated pipe connections, the first zinc-plated pipe connections and the second zinc-plated pipe connections respectively with it is zinc-plated
Pipe connects, and firing mount can be accurately sent into the predeterminated position of drilling；Detonator wire is worn mouth from detonator wire and is passed through, and from zinc-plated
It passes through in pipe and is connected with blowing out busbar, the generation of blind race accident can be led to avoid because pulling apart payment to a porter when powder charge and hole wall friction.
