Full-staged combination drilling with blasting mining method

The invention discloses a full-staged combination drilling with blasting mining method. A stage haulage roadway, an ore drawing access road and a cutting undercut roadway are arranged at the bottom of a room. The ore drawing access road serves as a haulage channel of caved ores in the whole stage. The undercutting roadway serves as a construction space of a fan-shaped medium-depth hole on the lower portion, the fan-shaped medium-depth hole is drilled upwards, and after blasting, trench undercut is formed. A cut raise is formed through one-time blasting of a large-diameter deep hole, and then a cut groove is formed through the cut raise to serve as an ore caving compensation space. A drilling chamber or a roadway which communicates with a transverse drift is formed on the top of the room to serve as a construction space of the large-diameter deep hole on the upper portion. The large-diameter deep hole and the fan-shaped medium-depth hole at the lower portion are combined for drilling. After the large-diameter
