Description

TECHNICAL FIELD

[0001] The utility model relates to big dip angle coal seam roadway support technical field, concretely is big dip angle coal seam haulage roadway surrounding rock geological support structure. BACKGROUND

[0002] The middle group coal is mined, and the coal seam spacing is small, and the upper coal seam mining has greater influence on the lower coal seam. When the lower coal seam is mined, due to the damage of the upper coal seam mining to the floor, the roof of the lower coal seam becomes more broken, and the strength of the surrounding rock is low. Even if the recovery roadway is arranged in the stress reduction area, the support is prone to appear near the coal pillar side shed leg breakage, deformation damage and bottom heave, and even the roadway collapse and other phenomena. Especially when the distance between the upper and lower two layers of coal is close, stress concentration phenomenon will appear near the bottom of the upper coal seam residual coal pillar, and when the lower coal seam roadway is excavated, it will be affected by the original rock stress and the stress of the upper mining, and the stress around the recovery roadway increases greatly, which puts forward higher requirements for the roadway support of the lower coal seam.

The drill rod is rotated into the vault, making the connection between the top rod and the vault more tight, and finally making the support more stable. However, the existing device does not solve the problem that the existing large-dip-angle coal seam haulage roadway surrounding rock geological support structure cannot adapt to different inclination angles in the haulage roadway, thereby failing to effectively support the surrounding rock geology of the haulage roadway. After supporting the surrounding rock geology of the large-dip-angle coal seam haulage roadway, the surrounding rock geology is prone to vibration during daily construction, and the vibration is prone to produce falling stones, thereby injuring the operators. When the support structure of the large-dip-angle coal seam haulage roadway is removed, the surrounding rock geology inside the haulage roadway is prone to damage, thereby causing the haulage roadway to collapse and other situations.
