Embodiment Construction
[0021] The present invention will be further described below.
[0022] Such as Figure 1 to Figure 4 Shown, concrete steps of the present invention are:
[0023] A. Select a position in the high-level drainage roadway 3 above the coal seam 1 to drill down the anti-reflection borehole 4, and the deepest part of the anti-reflection borehole 4 penetrates the rock layer and extends into the coal seam 1 without passing through the coal seam 1;
[0024] B. According to the depth of the anti-reflection drilling 4, select the required number of PVC pipes 9 to connect end to end to form a transmission line protection tube. One end of the transmission line protection tube is fixed with an ultrasonic vibrator 6, and this end of the transmission line protection tube is extended into the anti-reflection drilling 4 The other end of the transmission line protection tube is fixed at the opening of the anti-reflection drilling 4 through steel bars; the transmission line protection tube is pro...
