Mining environment reconstruction layering and striping medium-length hole ore removal mining method

The invention discloses a mining environment reconstruction layering and striping medium-length hole ore removal mining method comprising the following steps of: firstly, dividing a steeply inclined medium-and-thick unsteady ore shoot into stages; dividing a plurality of small divided layers in the stages; dividing a plurality of strip-shaped ore pillars in the divided layers, and carrying out mining in two circulations by taking the strip-shaped ore pillars as stoping units; in the first circulation, digging rock drilling passages in the strip-shaped ore pillars, expanding ventilating raises arranged on the tail ends of the strip-shaped ore pillars to form cutting grooves, drilling a medium-length hole, stoping in a side ore caving and retreating way, loading ores to be transported to a stage ore pass, transporting the ores to a ground dressing plant, filing high-grade filling materials to strip-shaped mined-out areas, wherein an alternate coordinated sequential stoping way is applied to the strip-shaped ore pillars inside the divided layers; in the second circulation, firstly filling the high-grade filling materials with certain thicknesses at the bottoms of the strip-shaped mined-out areas in a filling process, and filling low-grade filling materials into a residual space. The invention has safe and reliable mining environment, high ore recovery rate and production rate, low dilution loss, and the like.
