Ensure that whole medium-length hole is in ore body；
5), cutting groove molding: during explosion, well array is expanded in elder generation's explosion, after expanding well array explosion, explosion Ore is all gone out sky, then starts
Cut blasting is just being arranged and medium-length hole, and point 2 ~ 3 separate explosions complete.
Described cutting groove free of losses is without dilution process for stoping, it is characterised in that comprise the steps:
1), cutting lane arranges: cutting lane is arranged on stope in the ore body of dish end, and according to orebody strike, move towards layout and cut
Cut lane, and ensure that whole cutting groove is all in ore body；
2), construction cutting lane: according to orebody trend, construction drill chamber and cut well；Rig chamber arrangement is in side, stope border
Place, and near ore body thicker end, construct along stope border, ore removal i.e. stops construction；Cut well and be arranged in cutting lane and rig chamber
Infall, cuts well for construct vertically upward；
3), well array construction is just being arranged and is being expanded in cutting: cutting is just being arranged and constructed towards boundary line of ore bed and rock direction along stope route mouth, multiple cuts
Cut just arrange parallel and spaced apart；Expanding well array along parallel with it outside well constructing vertically upward cutting, multiple expansion well arrays are parallel
And it is spaced apart；
4), prepare before medium-length hole construction: after tunneling construction completes, prepare construction medium-length hole, for ensureing construction safety, well need to cut
Temporary preventive measure is done in lower section；
5), medium-length hole construction: expand well array, cutting is just being arranged and all medium-length hole rock junction, ore deposit of constructing stops construction immediately, and
Ensure whole medium-length hole in ore body, multiple medium-length holes interval be arranged to fan beam shape, the bottom-up construction of medium-length hole；
6), cutting groove molding: during explosion, well array is expanded in elder generation's explosion, after expanding well array explosion, explosion Ore is all gone out sky, then starts
Cut blasting is just being arranged and medium-length hole, and point 2 ~ 3 separate explosions complete, cutting groove explosive forming.
The invention have the advantage that
The present invention effectively reduces ore loss ratio, the rate of dilution, it is possible to reduces row's rock expense, improves mine grade, it is achieved upgrading increases
Effect, extends mine life.
