Bore construction method by bore explosion

The present invention provides a deep shaft one-step explosion well-forming construction method, and it is characterized by that three types of blast-holes can be drilled on the full face of the deepshaft, first type is of rock presplitting holes which are distributed along periphery of circular well to make peripheral smoothwall blasting, second type is of rock breaking holes which are distributed on the inner side of peripheral presplitting holes, and third type is of pulverizing holes with are distributed in the axis zone of shaft. The presplitting hole adopts non-coupled air column spaced charging powder, and the breaking hole and pulverizing hole adopt conventional non-coupled continuously-charging powder.
