Technical field
The invention belongs to coal mine timbering field more particularly to a kind of auxiliary branch that back inclination angle is adaptive
Protection unit and method for protecting support.
Background technique
Supporting coal mine underworkings are mainly the following form: (1) building arch supporting, this support pattern is by masonry shape
At the harder shell of ratio country rock protect country rock.This mode belongs to passive protecting, and not only support cost is high, speed of application
Slowly, large labor intensity, and it is unable to the large deformation of suitable for surrounding rock.It is unobvious to be currently mainly used in stress phenomena, geological condition
Relatively simple tunnel.(2) bolting and rope support is made the body of rod with metalwork, polymer member or other materials, squeezes into earth's surface rock
In body or the pre-drilled hole of chamber surrounding rock body, the special tectonic using end or the lane Anchor Agent Deng Jiang with cohesive action
Road surface country rock is combined together with deep rock mass, to achieve the purpose that supporting.This is that China's coal-mine tunnel is preferred, safe
Efficient main support pattern, significantly improves supporting effect of roadway, ensure that coal working face safely, quickly propel, promote
Into increasing substantially for coal production.But to the tunnel of certain complicated conditions, the effect of suspension roof support is undesirable.(3) U-shaped steel
Supporting, full name are the supporting of U-shaped steel compressibile support, divide the forms such as arch, circle and square annular.Belong to one kind of passive protecting.One
As be applied to pressure it is larger, the unstable tunnel of country rock, construct it is relative complex.(4) H-shaped steel supporting, full name I-steel contractibility
Trapezoid support, it is more stable suitable for country rock, it is influenced slightly by dynamic pressure, the small tunnel of deflection.It is generally used for gib, forever
Long supporting is relatively fewer.
Currently as the increase of coal mining depth, Tunnel Pressure are gradually increased, supporting is more and more difficult.Using single
Anchor shaft anchor cable or U steel supporting are difficult to meet the needs of production.
Summary of the invention
Since currently as the increase of coal mining depth, Tunnel Pressure are gradually increased, supporting is more and more difficult.Using list
