Embodiment Construction
[0036] The above-mentioned technical features and advantages of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some embodiments of the present invention, not all embodiments.
[0037] see Figure 1 to Figure 10 , shows the coal seam horizontal well hydrodynamic jet reaming coal digging and bag support forming roadway pressure relief method of the present invention.
[0038] The coal seam horizontal well hydrodynamic jet reaming hole coal removal and bag support forming roadway pressure relief method may include the following steps:
[0039] Step 1: Construct an L-shaped horizontal well in the coal seam 1, and lower the front end of the horizontal wellbore into a casing 4 made of non-metallic (such as: glass fiber reinforced plastics) for hole protection (see figure 2 ).
[0040] Preferably, the well location of the L-shaped horizontal well fully considers fact...
