Directional hydraulic drilling and mining integrated mining device and method for thin coal seam

The invention provides a thin coal seam directional hydraulic drilling and mining integrated mining device and method, and belongs to the technical field of coal seam mining, and the device comprises a steam-water separator, a three-stage settling tank, a solid-liquid separation device, a circulating water tank, a drilling and mining pump truck and a drilling and mining integrated machine which are communicated in sequence. The method comprises the steps that a drill site is formed in a roadway; mounting related equipment in the drill field; drilling is conducted through holes, discharged water is filtered and separated, and dropped coal is conveyed out; and after the whole in-hole drilling operation is completed, the second extraction pipeline is communicated for pressure relief gas extraction. The whole thin coal seam protective layer working face stoping is completed through the directional hydraulic drilling and mining integrated machine, roadway-free or roadway reduction operation can be achieved, workin
