Technical scheme:In order to realize foregoing invention purpose, the present invention the processing method for having dug fall of ground, including such as Lower step:
1) cleaning caved gangue, and choose and fall to emit dead zone surface loosening coal and rock in time after roof fall terminates;
2) i-beam frame canopy is installed by 0.8~1.0m array pitch in the range of Collapsed zone and Collapsed zone and 3~5m of both sides;
3) tile one layer of plank on the i-beam frame canopy installed;
4) filling bag is placed on plank, and the bottom surrounding for filling bag is followed closely on plank;Described filling bag bottom Provided with the multiple cuffs led in it;
5) rigidity pipeline is stretched into bag from the cuff of filling bag bottom, one end of pipeline, which will be filled at the top of bag, supports to kiting Area's highest point, the pipeline for being exposed at the outer one end of cuff are connected with filling piping;
6) cuff of filling bag bottom is tightened, is extremely full of by slip casting in steel tube road direction filling bag and entirely emits dead zone;
7) after grouting serous fluid solidification, more anchor cables are set emitting dead zone, plank is compressed with pallet, and apply pretightning force, Complete the processing to having dug fall of ground.
Described i-beam frame canopy quantity determines according to roof fall situation and roadway engineering geological conditions.
It is described filling bag shape it is similar to emitting air region shape, each side size ratio emit the dead zone big 0.5m of correspondence position size~ 1m。
Multiple cuffs of the filling bag bottom are 2~4.
Described rigidity pipeline is 2~4, is matched with cuff number.
Described cuff diameter is bigger 0.1~0.3m than rigidity pipeline diameter, and cuff length is 0.1~0.5m.
The length of the anchor cable is bigger 1.5~3m than the maximum height for emitting dead zone, between anchor cable array pitch according to roof fall situation and Roadway engineering geological conditions determines.
The pipeline is rigidity pipeline or pvc pipe road.
The plank thickness is 1.5~3cm.
Beneficial effect:By adopting the above-described technical solution, the present invention utilizes the supporting role and anchor cable of i-beam frame canopy Suspension function, can also actively provide pressure to dead zone surface coal and rock is emitted by obturation while ensureing that obturation is stable Stress, elimination emit the hanging face in dead zone, and improvement emits dead zone surface coal and rock force environment, improves its stability, effectively prevent and emit Dead zone inbreak again under Engineering Disturbance effect, its method is simple, easy to operate, strong applicability, has in the art Wide applicability.
