It’s spring now, so I ask myself what I want.
Su Nuan Xie white wine, milk and rehmannia glutinosa porridge.
Not only does it relieve cravings, it can also regulate a sick stomach.
There is dry fish to help drink, and it is also used as a meal.
Don’t recite the previous philosophy, you will feel ashamed when you are drunk and full.
Don’t you hear that Mr. Jingjie’s bottle is in the sky and Mr. Guangwen’s rice is not enough.
Question: What are the components of the surrounding rock loose zone measuring instrument?

Answer: The surrounding rock loosening circle measuring instrument consists of a host, a probe, a power supply, etc. The host is explosion-proof, intrinsically safe for mining, the power supply is ~, the weight is gram, and the resolution is. Dimensions: ** Probe main frequency
Wire: RF wire, drilling diameter: ~Power battery: No. Working voltage of ordinary alkaline dry batteries: Working current:
Question: How to use the surrounding rock loosening circle measuring instrument?
Answer: Before use, please check the power supply voltage and probe insulation resistance before use: Power supply voltage: After turning on the machine, the red power indicator light will be on. Each battery pack can measure ~ 1 drill hole. Probe insulation resistance: The positive electrode of the transducer should meet the insulation resistance, otherwise the transmitting and receiving capabilities of the instrument will be affected, and it may even fail to work properly. Simple identification method: Connect the two transducer wiring nuts to the transmitting terminal on the left side of the instrument respectively. After turning on the power switch, there should be a snapping sound every second. If there is no sound, it means there is a problem with the transducer, and the wires need to be checked. Is there any open skin short circuit or other phenomena or replace it.
Test work
Scan the borehole to remove rock (coal) powder and gravel (coal) ballast in the hole
Check the recorded data, decide whether to retest, and initially determine the loosening range of surrounding rock fissures
br/>Send the probe to the bottom of the hole, insert the hole sealer into the hole and fix it (no hole sealer is needed when drilling holes downwards with both sides)
Inject water. When there is continuous water flowing out from the end of the measuring rod, it indicates that the water has been filled
To test the reading, twitch the probe outwards one by one, and time the reading
Q: What are the main functions of the surrounding rock loosening zone measuring instrument?
Answer: It is used to detect the looseness of surrounding rock and the scope of cracks, and provides scientific basis for the design and construction of tunnels. The instrument is intrinsically safe for mining. It can be used for qualitative analysis of surrounding rock in gas mines, metal mines, tunnels and underground projects.
