Efficient And Comprehensive Drilling Technology Alternative Air Dth Hammer


Technical Parameters:

Comparison of liquid-driven hammer drilling process and air DTH hammer drilling process
DTH-HAMMERCOMMAND liquid-driven hammer
Applicable strata
Complete bedrock formation, or hard rockLike the DTH-hammer, the crushing efficiency is extremely high for hard formations.
Unsuited StratumThe mud acts as a medium for the impactor, essentially mud drilling. Mud drilling is suitable for a variety of formations. And the wall protection ability is strong, it is not easy to collapse, and the fractured formation can also be processed by filling.
Sandy soil layers, fractured strata and other loose formations, when loose formations will blow up the walls of the holes, or blow into small "big bells", if the air compressor model is not well matched, it will cause drill cuttings at the bottom of the hole. Suspended in the wellhead, can not blow out, resulting in buried bottom and other hole bottom accidents.
Matching equipment
Drilling rigDrilling rig
Generally hydraulic power head drillThe rig can be in various forms, and the COMMAND uses a truss structure, which is a high-strength square tube welding, has a high load and good torsion resistance, and is suitable for various aperture construction. The drilling diameter is 505MM.
The rig is a combined I-beam or channel steel structure that is lightweight but does not have torsion resistance. Therefore, it is only applicable to the air DTH hammer drilling process which does not require a large torque, and the general aperture can only reach within 200MM.
Air compressorMud pump
Selection basis:Selection basis:
Air flow: annular gap between drill pipe and hole wall (aperture)Flow: Ring gap between drill pipe and hole wall (aperture)
Wind pressure: depthPressure: Depth
Commonly used air compressors can only reach a depth of about 280 meters, the deeper the cost is, the higher the cost is.Mud pump is the basic component of drilling rig. Because of the ever-changing strata, mud drilling must be used to solve complex strata.
The selection of mud pump only needs to be based on the depth and aperture of normal mud drilling.

describe

1. drilling rig is a kind of medium and high efficient full hydraulic multifunctional water well drill rig for drilling up to 300m and is used for water well,monitoring wells, engineering of ground-source heat pump air-conditioner,blasting hole, bolting and anchor cable, micro pile etc.

2. Compactness and solidity are the main characteristics of the rig which is designed to work with several drilling method: reverse circulation by mud and by air, down the hole hammer drilling, conventional circulation. It can meet the drilling demand in different geological conditions and other vertical holes.

3. The rig can be either crawler, trailer or truck mounted and it can be personalized according to the various customers’ requirements.
