Summary: | The invention provides a shed and cable collaborative anchor protection method and device for asymmetric deformation control of a dynamic pressure semi-coal rock roadway. The shed and cable collaborative anchor protection method comprises the following steps that S101, a U-shaped shed is built in the formed semi-coal rock roadway through limiting clamping cables; s102, after the U-shaped shed is built, mixed concrete is used for conducting guniting and filling on the half coal rock roadway supported by the U-shaped shed through a slurry pump to form a behind-wall filling body, the U-shaped shed and the half coal rock roadway are fixedly connected through the formed behind-wall filling body, and then the coal rock interface position is positioned and marked on the half coal rock roadway subjected to guniting; s103, the marked coal and rock boundary position of the half coal and rock roadway is drilled; and S104, a layer-penetrating pre-stressed anchor cable penetrates into the drill hole in the coal-rock bound |
