Vertical comprehensive mechanical mining method for super-thick potassium salt deposit

The invention discloses a vertical comprehensive mechanical mining method for a super-thick potassium salt deposit, and belongs to the technical field of mining of potassium salt deposits. The vertical comprehensive mechanical mining method for the super-thick potassium salt deposit can reduce reservation of protective mining pillars, improve the resource recycling rate and improving the filling ratio of a goaf. According to the technical scheme, firstly, mining roadways are arranged on the upper portion and the lower portion of a mine correspondingly; secondly, vertical mining pillars are arranged at certain intervals, a plurality of mine slide holes are pre-constructed in each vertical mining pillar, and an ore conveying system is arranged on the mining roadway of the lower portion; thirdly, in the mining roadway of the upper portion, a mining machine is used for mining the mine along the arranged vertical mining pillars; fourthly, goaf filling is conducted; and fifthly, the first step to the fourth step ar
