The influence of aquifers on the roof and floor of coal seams on water well drilling rig operations
Aquifers often distribute in coal seam roof and floor, whose water abundance and pressure directly affect the safety of water well drilling rig operations.
- When the borehole penetrates the aquifer, massive water inrush may occur, flooding the borehole, damaging equipment, and even causing water inrush accidents.
- Scouring of aquifer water will destroy the stability of borehole walls, increasing the risk of collapse.water well drilling rig
Before operation:
3. Find out the distribution, thickness and water pressure of aquifers by geophysical exploration, drilling and other means, and formulate waterproof measures.
4. For aquifers with high water pressure, grouting water plugging technology can be used to form a water-stop curtain around the borehole.
5. Monitor the changes of water inflow and water pressure in real time during drilling. If any abnormality is found, stop drilling immediately and take corresponding treatment measures to ensure construction safety.
