Method for accurately controlling mining width of medium-length hole mining in steeply inclined thin and fine ore body

The invention discloses a method for accurately controlling the mining width of medium-length hole mining in a steeply inclined thin and fine ore body. The method comprises the following steps that S1, a stope is arranged in the direction of the ore body, ore blocks are divided, a raise is tunneled and cut, and a blasting free face is formed; s2, the ore blocks are divided into a plurality of stoping units, and according to the cutting mining technology, transverse edges of a stoping unit group are cut firstly, and then longitudinal edges are cut; s3, according to the drilling design requirement, a rock drill is adopted for drilling, and process control comprises process parameters of drilling deflection, hole depth and spacing; s4, charging blasting is carried out, and the charging mode of a downward charging device is adopted; s5, ore removal: carrying out shoveling and ore removal by using a forklift in an ore removal roadway; and S6, the step S2 to the step S5 are repeated until the whole ore block is sto
