Ensure that tunneling boring protects.Meanwhile first the tip at telescopic fixing rod 10 and 20 both ends of the second telescopic fixing rod sufficiently connect with lane side
Touching, guarantees protection intensity, and the fixed device 103 of fastening first and the second fixed device 203 guarantee grafting intensity.When work of meeting head on is complete
Finish when needing drilling depth, protective net is unloaded, and properly saves, with this circulate operation.It meets head on that wall caving, fried side or bump thing occurs
Therefore when, protective net effectively or can be wrapped up largely, stop to leave coal body, and buffered coal body and left speed, strength, and guarantee leaves coal body
Will not bury meet head on operating personnel or reduce to operating personnel injure.
Liuhuanggou coal mine rock blast hazard is more serious, and especially in driving face, surrounding geological condition constantly changes,
Cause driving face stress cannot in time, be released effectively.04 belt crossheading driving face of Liuhuanggou coal mine (4-5) tunnels the phase
Between, situations such as working face dynamic phenomenon shows more frequently, wall caving of meeting head on, fried side, roof fall, happens occasionally, and personnel's operation safety is not
Energy effective guarantee, especially operating personnel is when meeting head on to construct destressing borehole, if working face stress is more concentrated, easily because construction is unloaded
Pressure drilling induces bump.By protective net of the invention after Liuhuanggou coal mine is on probation, it was demonstrated that bump of the invention
Soft protecting net effectively or can be wrapped up largely when meeting head on that wall caving or Dynamic events occurs, stop to leave coal body, and buffer coal body
Leave speed, strength, guarantee, which leaves coal body and will not bury the operating personnel or reduce of meeting head on, injures operating personnel.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
