Background
At present, in the gob-side entry retaining technology, because of the limitation of technical conditions, the retained roadway is generally subjected to gangue retaining support by using I-shaped steel or U-shaped steel by adopting an engineering-like comparison method so as to prevent the retained roadway from being damaged by gangue from a goaf.
The utility model discloses before, the utility model discloses a novel let pressure formula collecting space area waste rock isolating device is published to application number 2017210846167, and the device comprises I-steel support, reinforcing bar net, adjustable vaulting pole, adjusting bolt, fixing device and card cable, can effectually prevent that the waste rock from leaping up, plays certain supporting role to the tunnel roof simultaneously, but the device can't quantitative monitoring tunnel roof to the axial pressure of keeping off the waste rock body, also can't monitor the lateral pressure of collecting space area waste rock to keeping off the waste rock body simultaneously.
Therefore, the device can monitor the pressure change, and when the device blocks the waste rock in the goaf, the device can also monitor the axial pressure applied to the waste rock blocking body and the lateral pressure from the waste rock in the goaf quantitatively, help the staff to analyze the effect of the existing waste rock blocking support, and provide data support for the waste rock blocking support design of the follow-up working face.
Disclosure of Invention
The utility model aims to solve the technical problem that to prior art not enough, provide a can monitor pressure variation's fender waste rock device, at gob entry in-process dynamic monitoring tunnel roof to the axial pressure of the fender waste rock body to and collecting space area waste rock guarantees the safe high-efficient production of mine to the lateral pressure of the fender waste rock body.
The utility model aims at realizing through the following technical scheme:
a waste rock blocking device capable of monitoring pressure change is characterized by comprising a waste rock blocking body, wherein a lateral pressure sensor is mounted at the front part of the waste rock blocking body, and a lateral pressure-bearing steel plate is arranged at the front part of the lateral pressure sensor; an axial pressure sensor is arranged at the upper part of the waste rock blocking body, and an axial pressure-bearing steel plate is arranged at the upper part of the axial pressure sensor; the back of the waste rock blocking body is provided with a control module, and the control module is powered by an explosion-proof battery.
Furthermore, in order to make the staff know the pressure that the waste rock blocking body receives in the use, the control module be provided with display screen.
Further, in order to carry out the early warning to the monitoring data, the right side of display screen is provided with the pilot lamp, and when the monitoring pressure value exceeded the settlement threshold value, the pilot lamp can twinkle.
Furthermore, in order to realize the wireless transmission of the monitoring data of the device, the control module is provided with an antenna head.
Further, in order to enhance the acid-resistant and oxidation-resistant effects of the device, the surfaces of the lateral pressure-bearing steel plate and the axial pressure-bearing steel plate are coated with organic silicone oil coatings.
