In order to change the high risk, high construction cost, and low production efficiency of the manual cuttingshaft slotting technology in Pingquan Xiaosigou Mining Co., Ltd., by analyzing the characteristics of various slottingtechnologies and considering the mining characteristics of the Xiaosigou Copper Mine, such as high ore chambersublevels, long slotting lengths, and medium‑hard rock, the upward bundle medium‑long hole blasting and micro‑differen‑tial sublevel single blasting technology were utilized to achieve the non‑cutting shaft slotting technology of upwardbundle medium‑long hole micro‑differential sublevel single blasting slotting and multi‑time blasting slot expansion.Based on this technology, slotting tests for upward bundle medium‑long hole slot initiation and slot expansion wereconducted in the molybdenum mining area from the middle Exploration Line 10 to Exploration Line 12 at the 630 mlevel in the Xiaosigou Copper Mine, achieving good test results, solving practical problems in the mine and promotingthe technology at the 630 m, 598 m, and 581 m levels. This technology not only changed the current situation of cuttingshaft and slotting roadway in the mine, but also showed high applicability and controllability in high sublevels of medium‑hard rock, effectively ensuring the safe, efficient, and stable production of the mine.
