The thickness and burial depth of coal seams are key bases for
selecting water well drilling rig.
- For shallow thin coal seams (thickness < 3m, depth < 200m), small portable rotary rigs meet needs with flexible operation and low costs.
- For thicker seams (>6m) or greater depths (>500m), choose high-power deep-hole rigs like hydraulic power head rigs:
- They have large torque and strong drill pipe strength, adapting to complex deep geological conditions.
- Considering ground stress differences at different depths, also ensure rig stability:
- Equip suitable foundation treatment and anchoring devices to keep the rig stable during drilling for efficient construction.water well drilling rig
