Abstract
The utility model discloses a sloughing preventing device, which comprises a shelf, wherein the shelf is arranged erected in a tunnel, the top of the shelf is respectively and fixedly welded with a plurality of forestopes, the two ends of each forestope are respectively and fixedly welded with a skeleton which is surrounded by a plurality of steel pipes, each skeleton is fixedly provided with a steel wire net, and the steel wire nets are tightly attached on the rock wall of the inside of the tunnel and cover the cross section of the rock wall to form a sector-shaped sloughing preventing net. The sloughing preventing device has the advantages that the structure is reasonable, the occurrence of sloughing accidents in the coal mine working area is avoided, workers working on evacuating surfaces are maximumly protected, the injury to the workers due to sloughing and rock leaking is avoided, and the safety coefficient is improved.
Description
Technical field
The utility model relates to a kind of anti-wall caving device.
Background technology
Wall caving refers to that mine operation face, tunnel sidewall are out of shape under action of underground, destroy and the phenomenon that comes off.In the coal mine roadway of complex geologic conditions, its work plane has the possibility that side falling accident occurs constantly, and the personal safety when the coal miner coal mining activity is arrived in serious threat is especially when coal miner meets head on to carry out coal mining activity, in case the generation side falling accident, its consequence is hardly imaginable.
The utility model content
The purpose of this utility model provides a kind of anti-wall caving device, prevents that the coal mine working zone from the generation of side falling accident occuring, the safety factor during with raising coal miner coal mining activity.
The technical solution of the utility model is as follows:
A kind of anti-wall caving device, include the frame that is erected in the tunnel, the top of described frame is fixedly welded with respectively a plurality of forestopes, it is characterized in that: the two ends of each forestope are fixedly welded with respectively the skeleton that is surrounded by many steel pipes, be installed with gauze wire cloth on the described skeleton, described gauze wire cloth is close on the crag in the tunnel, and covers the section of crag, forms fan-shaped anti-wall caving protective screening.
The anti-wall caving device of stating is characterized in that: the mesh diameter of described gauze wire cloth is 100mm, and gauze wire cloth is not more than 3m apart from the height of frame bottom, and has the gap that is not more than 300mm between the adjacent steel silk screen.
The beneficial effects of the utility model:
The utility model is rational in infrastructure, prevents that the coal mine working zone from the generation of side falling accident occuring, and farthest for the workman in the work of meeting head on plays protective effect, has avoided because of wall caving, has leaked the injury that spoil brings to the employee, has improved safety factor.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to Fig. 1, a kind of anti-wall caving device, include the frame 1 that is erected in the tunnel, the top of frame 1 is fixedly welded with respectively a plurality of forestopes 2, the two ends of each forestope are fixedly welded with respectively the skeleton 3 that is surrounded by many steel pipes, are installed with gauze wire cloth 4 on the skeleton 3, and gauze wire cloth 4 is close on the crag in the tunnel, and cover the section of crag, form fan-shaped anti-wall caving protective screening.
In the utility model, the mesh diameter of gauze wire cloth 4 is 100mm, and gauze wire cloth 4 is not more than 3m apart from the height of frame 1 bottom, and has the gap that is not more than 300mm between the adjacent steel silk screen.
