Cutting groove is an important mining technology of sublevel caving method.The quality of groove greatly influence the effective of subsequent blasting and mining of the ore room column.It uses a conventional method of self-cutting with cutting raise for the mining area with soft and breaking orebody,but there are some great potential safety hazards,such as constructing cut well and setting up platform and alternating blasting order and so on.The method of fan-shaped medium-length hold blasting self-cutting with non-cutting raise can surmount above deficiencies which is simple to construct with high quality of self-cutting,saves the cutting patio construction and ensures people operation safety radically.The method has a broad promotion and application value.

Key words: non-cutting hole, middle-deep hole blasting, Hongqigou-Shenshuitan gold mine
