Embodiment Construction
[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0020] Such as figure 1 Shown, a kind of short-wall hydraulic coal mining method comprises the following steps:
[0021] Step 1: In the area where the inclined coal seam is to be mined, along the direction of the coal seam strike, the phase of the hydraulic coal mining face is arranged at a pseudo-incline at an angle of about 10-20° to the coal seam inclination, and the return air channel 2 and the recovery channel are formed to form a small trend stage Coal mining method, each coal seam is jointly arranged for mining, single-wing or double-wing mining of the coal seam, downward mining within the stage, the mining of the first small-stage working face 1 is completed, and then the second small-stage working face 10 is mined; the size of the working face is determined according to the coal seam assigned In general, the inclination leng...
