The influence of coal seam thickness and burial depth on the selection of water well drilling RIGS

The thickness and burial depth of coal seams are key bases for selecting جهاز حفر آبار المياه.

 

  1. For shallow thin coal seams (thickness < 3m, depth < 200m), small portable rotary rigs meet needs with flexible operation and low costs.
  2. 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.
  3. 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
