Description
Technical field
The utility model relates to colliery tunnel support technical field, specially a kind of coal mine roadway list slot single-beam gate-type supporting
Device.
Background technique
China's coal-mine is mainly underground mining, needs to dig a large amount of tunnels in underground, safety of coal mines, efficiently production depends on
The unimpeded and stabilization in tunnel.As the continuous improvement tunnel buried depth of mining depth, range and mining rate increases year by year, geology item
Part increasingly complex, high-ground stress tunnel, strong mining influence tunnel, soft and broken surrounding rocks tunnel and extra-large cross-section tunnel and cave
The appearance of the complexity hard situation such as room, Roadway Support Technology are also changed constantly.Existing support pattern have passive protecting and
Two kinds of active support, wherein passive protecting refers mainly to fashioned iron supporting, and fashioned iron supporting is by bracket to the support action of roadway surrounding rock
Backboard between country rock transmits drag, and this drag is a kind of passively support pattern.The viewpoint of this supporting is at the very start
All country rocks are all considered as load.And there is no prestressing force for contact of the backboard with country rock, passively country rocks can only be waited to carry out buckling
Shape；Anchor pole, anchor cable and bolt-mesh-spurting supporting belong to active support, can make the Bolted Rock Masses formed by bolting with wire mesh, be suspended to
In the rock stratum of top hard and steady, avoids roadway roof absciss layer and back integral sinking or be caving.Bolt-mesh-anchor support mode
It has been increasingly becoming support pattern important to Soft rock tunnel in recent years；However why anchor pole can play roadway surrounding rock
Support action is that have self bearing capacity and energy Selfstabilizing because of country rock itself, but the effect of anchor pole is limitation country rock
Rock mass makes it keep continuous modification.In the supporting construction of one Liang Sanzhu, the intensity of lateral column and beam body link position is always inadequate.Cause
This, needs research and development more preferably roadway support device, improves supporting effect, and to adapt to, task difficulty is big, working face mounting bar
The driving mining operations requirement of the poor coal mine such as part, efficiently ensures production operation safety.
