2018, etc.).
The product has passed the technical testing of "National Safety Production Fushun Mining Equipment Testing and Inspection Center", and the product has been obtained.
Coal safety mark certification, reliable explosion-proof performance.
On December 27, 2018, the product technology passed the appraisal of China Coal Industry Association, and the conclusion was international advanced water.
Ping. This is the latest authoritative technical conclusion for borehole trajectory measuring instruments in China, which proves that the product technology has
Some originality, advanced nature
.
2. Applicable environment and application comparison
2.1 applicable environment
Used in the underground high gas, high dust, high humidity environment, all types of coal mine short geological drilling.
(Geological exploration hole, gas drainage hole, water exploration hole, grouting reinforcement hole, etc.).
2.2 Application Comparison
At present, the following three methods are mainly used to measure the trajectory of short and shallow holes in coal mines:
hand drawnRig positioning measurement outside the hole: measuring the drill pipe positioning before drilling, and estimating the drilling trajectory based on the positioning value;
hand drawnPost-drilling secondary push measurement: after the drill pipe is withdrawn at the end of drilling, the measuring instrument is pushed to the drill with a push rod.
In case of hole collapse, the whole hole trajectory measurement cannot be completed;
hand drawnMeasurement while drilling: install the instrument and drill pipe in an integrated way, measure while drilling, and measure how deep the drill is, and finish it at one time.
Drilling and trajectory measurement.
After the product passes through the matching non-magnetic drill pipe or push rod, it can realize the measurement while drilling or the secondary propulsion measurement after drilling.
